Super Natural or Super Tanker?

Northern Resident Killer Whale R12 (male born in 1967) in Caamano Sound – part of the proposed tanker route that would carry bitumen crude along B.C.’s fragile coast. Photo by James Pilkington taken during the time he spent 3 seasons at a remote outpost documenting the biodiversity of the area for the North Coast Cetacean Society. http://www.cetacealab.org/

August 8, 2012: Last night and this afternoon concerned Northern Vancouver Islanders resolutely, passionately, creatively, eloquently and unequivocally said “NO” to the Enbridge Northern Gateway Project. Below, is the text that I used to guide my testimony to the Joint Review Panel:  

My name is Jackie Hildering and I speak from the perspective of a marine educator who has lived in this area for 13.5 years. I moved here after a 14-year international teaching career choosing B.C.’s Coast specifically because of its extraordinary marine biodiversity and what I perceived to be the potential to leverage this biodiversity to motivate people to undertake positive environmental change.    In my years here:

  • I have worked as a whale watching naturalist for a company serving some 10,000 guests a year of which a conservative estimate is that 65% come from outside British Columbia;
  • For 8 years, I was DFO’s Education Coordinator for this area;
  • I am a humpback whale researcher; and
  • I am a very avid cold-water scuba diver using my underwater experiences and photographs, in addition to the marine mammal engagers, in my education and conservation efforts.

I am the 2010 recipient of the Vancouver Aquarium’s Murray A. Newman Award for Excellence in Aquatic Conservation and have received written commendation for my work from DFO’s Director of Oceans, Habitat and Enhancement. I share this depth of personal background with you to fortify my testimony:

  • On how extraordinary the marine biodiversity of this area is;  
  • The value of the resources being put at risk; and
  • That this risk is simply too great to allow the marine transport of bitumen in the proposed area.

It is an inescapable conclusion that the transport of bitumen crude along our Coast constitutes a massive gamble where human ingenuity is being pitted against the resilience of Nature and our dependence on it. I can testify that this marine ecosystem is extraordinary on a global scale. I have photographed invertebrates that were previously unknown to science, and have participated in documenting rare organisms such a corals and glass sponge reefs at depths much shallower than what had been previously documented.   I acknowledge however, that when there is such absence of knowledge, it is more difficult to make the case for how the life hidden below the surface may be impacted by this Project. Therefore, I will use the marine mammals and what we do know about them as ambassadors for the fragility of the other life below the surface. The marine mammals that have been acknowledged to be at risk in the area are the:

  • Species of Special Concern – the harbour porpoise, gray whale, Steller sea lion, and sea otter;
  • Species recognized as being Threatened – humpback whale, fin whale, northern resident, and transient killer whales; and
  • The Endangered southern resident killer whales and potentially, blue whales and sei whales.

In fact, bitumen transport would take place through what has been acknowledged by government to be critical habitat for humpback whales, and what is candidate critical habitat for northern resident killer whales and fin whales. The marine mammals, to varying degrees, have survived culling and whaling but continue to experience the treats of reduced prey availability, bioaccumulation of toxins, ocean acidification and further impacts of climate change, noise, vessel strike, entanglement, and more. The anthropogenic impacts on these species’ survival would indisputably be amplified further by this Project due to chronic noise and increased risk of ship strike. As a humpback researcher, I can attest to how oblivious this species can be to boats. I have watched them surface directly in front of motorized vessels after previously having been 400 plus meters away. When one considers the size of the tankers, how narrow the inlets are, the difficulty in adjusting the course of these large vessels, the density of humpback whales, and the potential weather conditions – vessel strike of humpbacks is a very real risk and one that cannot be mitigated by the presence of marine mammal observers. The humpbacks are going to be there.  Then what? Outside of concerns about the noise and further traffic impacts to the marine life, and what this means to their survival, the potential losses that would result from a spill are simply the stuff of nightmares.  When something goes wrong – then what?  It is my understanding that, at best, when there is a spill there would be 15% recovery. And we can’t hope for “at best” – seen Enbridge’s performance record; the likely wind and wave action that would be associated with a spill; that the federal government is closing B.C.’s command centre for emergency oil spills and centralizing operations in . . . Quebec; and that the closure of a Coast Guard base and three marine communication centres in B.C. will leave only two marine communication centres to monitor B.C.’s 27,000 kilometres of coastline.  And after the spill, with irreversible and catastrophic loses, what mechanism is there to hold industry accountable? What is there when, concurrent with the review of a Project such as this with the potential for devastating impacts, the government is atrophying or removing the checks and balances the would allow appropriate assessment of risk? The latest Harper statement is that science, not politics, will drive decision making around such projects. How?

  • The ocean contaminants program will be all but be shut down;
  • Government researchers, whose work has been paid for by the taxpayer, are stifled in their communications;
  • Bill C-38 has gutted Canada’s Fisheries Act, undermined the Species at Risk Act and repealed the Canadian Environmental Assessment Act and it was done in such a way that even the Conservatives could not vote against it since, to defeat an omnibus budget bill is to defeat one’s own government;
  • Testimony at the Cohen Inquiry into the Decline of Fraser River Sockeye has made clear how government bodies are made to work with industry rather than safeguard our natural resources – even a keystone species; and
  • Environmental governmental organizations are more overwhelmed than ever as a result of these many attacks against science and the environment in addition to now struggling under the needless scrutiny and vilification by our federal government.

This current government climate is the epitome of decision-making based on short-term economic gain over long-term environmental health. I solidly believe there is another economic path that does not put our resources at risk in the way that marine bitumen transport would and where there is so much to lose economically, socially, and culturally. As a result of my work, I believe we have not come close appreciating nor maximizing the economics of the international attraction of British Columbia for its natural splendor. Outside of the First Nations, our culture has largely been one of being gold-rushers, and I think we, the keepers of paradise, often don’t know that we are in it. We don’t fully recognize how extraordinary B.C.’s Coast is and therefore don’t understand adequately what is being put at risk.   There is certainly an element of taking our resources for granted, and increasingly, that society does not appreciate our connection and dependency on them. Therefore, we fall short in our ability to attract and capitalize on B.C.’s international wild appeal and we are not inclined to move toward a greener economy nor to adequately protect our environment. I can testify to the potency of our Coast to attract those looking to connect to the wild, to view giants, and breath in the sense of space and raw beauty of this area and how I believe this can be capitalized upon economically, while creating societal good. It is of course so difficult to measure, but I will also dare state, based on my experience in the trenches of conservation, that the connection to the wild positively impacts, inspires, fortifies and empowers humanity in a way that cannot be achieved in an urbanized setting. [And this is where I virtually lost it and needed to choke out the remaining words.] We simply need places like this and can’t expose them to this kind of risk. My position on the decisions Panel should make is:

  • The potential of environmental impact is too great and cannot be mitigated for;
  • There is too much at risk – environmentally, economically, culturally and socially; and
  • That therefore, transport of bitumen crude cannot take place along B.C.’s fragile and extraordinary coast and the Enbridge Project must not be approved.   

Simply, we should be capitalizing on this being Super Natural British Columbia, not Super Tanker British Columbia. 

 

Rockfish Barotrauma

Update: September 2022
New paper – Hailey L. Davies, Shane Gross, Dana R. Haggarty, Francis Juanes (August, 2022)- PHOTO DIARY – Conserving Rockfishes: Barotrauma and Descending Devices in the Northeast Pacific, Fisheries Magazine.

Get the app that alerts you when you enter a Rockfish Conservation Area.

Update: Fisheries Notice March  25, 2019
The use of a descending device is now required by condition of licence to assist in the conservation and survivability of rockfish being returned to the water. Because of their closed swim bladders, rockfish brought to the surface suffer barotrauma, causing the swim bladder to inflate and reducing the probability of their survival upon release. Handle catch as little as possible, using wet hands to preserve the protective slime coat, and return to the water at depth of capture as quickly as possible (under two minutes). To avoid catching rockfish, move to another fishing location.”

_______________________________________________

This photo is of a Yelloweye Rockfish that has died from barotrauma, also known as “pressure shock”. 

Yelloweye Rockfish that has died of barotrauma. Reduced water pressure causes the air in the swim bladder to expand and push out the esophagus and eyes. BUT this is a reversible condition whereby the fish can survive through use of a “fish descender”. Photo: Hildering. 

Many rockfish species are particularly sensitive to reductions in pressure since the air in their swim bladders expands substantially. The swim bladder is a buoyancy control organ and even when slowly reeled in from a depth of only 20 m (60’), a rockfish’s swim bladder can expand to three times its size, putting pressure on the fish’s organs.

As is the case with the Yelloweye Rockfish in the photo, the swim bladder can expand to the point of causing the fish’s eyes to bulge out of their sockets and its esophagus to be pushed out of its mouth (the esophagus is the first section of the digestive tract). I know this is likely a sight that may not enhance your appetite for your rockfish catch but please read on since, contrary to the thinking of many, this IS reversible whereby the rockfish stands a good chance of survival.

Colossal “management” errors were made with overfishing slow-growing rockfish. Many species are extremely long-lived, slow to sexually mature, and the big, old females are the most fertile – producing the most eggs and hatching the largest number of healthy young.

For example, Yelloweye Rockfish are believed to have a lifespan of up to 118 years. They don’t reproduce until they are at least 12 years old, and the old females can incubate up to 2.7 million eggs! Know that there are 38 species of rockfish off the coast of British Columbia. 

This means that species are very slow to reproduce whereby, if you catch lots, especially the big females, you can devastate populations very quickly.

Another nail in the coffin of rockfish is that many adults also have high site fidelity so that by fishing one area, you can wipe out a community of fish. Click here for my blog on having found back the SAME individual rockfish in the SAME spot after EIGHT YEARS. This is why Rockfish Conservation Areas (RCAs) are essential, where it is most often illegal to do any hook and line fishing (see restrictions here). 

But, what is you accidentally catch a rockfish outside these areas?

There are studies that support that if you were to quickly recompress the fish, it would stand a very good chance of survival, even where it appears dead at the surface. The fish could be brought back to depth with barbless weighted hooks, or commercial “fish descenders”.

This video make the life-saving potential of fish descenders very clear.

From Island Fisherman Magazine: “Common types of descending devices include a simple, inverted barbless hook, a spring-loaded clamp, and a pressure-release clamp. Of the different devices available, the most effective and simplest to use is a depth pressure activated release device, the Seaqualizer . . . Automatically opening at preset depth, the motion of the boat or the actions of the rockfish as it descends will not prematurely release the fish.

Examples of fish descenders:
Seaqualizer Fish Release Tool (~ $60 CAN)
(Recommended by various fishing organizations and publications)
Shelton Fish Descender (~$8 CAN) 
SeaQualizer SeaYaLater Fish-Release Hook (~$20 CAN)”

If you can act quickly enough (which is essential) you can even use and inverted, weighted milk crate. See clip below AND this link for making your own descending device.

How wonderful it would be if more people would undertake the effort to recompress the fish, knowing how dire the situation is for many rockfish species. Imagine the further positive impact if people would choose to return the depleted species to depth even when they haven’t reached their catch limit, especially the big, highly productive females.

But, even if there was to be such enlightenment, many rockfish populations are so depleted that they need far more protection.

Again, Rockfish Conservation Areas (RCAs) are essential. These should be areas known to be the territory of depleted rockfish populations. Since these are no-fishing zones, there is no chance of barotrauma and the rockfish populations that live in the area are given the time to rebuild to have more sexually mature fish and more big old super mamas.

In summary, it’s so easy to contribute to rockfish conservation:
(1) Respect Rockfish Conservation Areas knowing that you usually cannot do ANY hook and line fishing there; and
(2) Invest in a fish descender for rockfish caught outside RCAs.

Long live rockfish!

An Honour – Pacific Northwest Diver “Featured Photographer”

Something made me clap my hands and giggle in glee today.

Of course I want to share the cause with you but, first, a bit of context. 

I am 49 years old.

I only started diving in 1999 at age 36.

I resisted taking underwater photos until 2006, not wanting to take my above-the-ocean marine photo addiction underwater with me.

Then I was gifted an underwater camera and very soon discovered the huge conservation power of sharing these photos with others, especially when coupled with my teaching.

In 2010, “The Marine Detective” erupted, better unifying my teacher, whale researcher, photographer, and  conservationist selves and making it just a little easier to answer “So what is it you do?!”

Then there was that amazing Murray A. Newman Aquatic Conservation award  from the Vancouver Aquarium . . .

And now, I feel another milestone has been reached in whatever path The Marine Detective is on.

I am this month’s “Featured Photographer” in Pacific Northwest Diver Magazine. 

I have had the great privilege of my photos getting used for a variety of conservation purposes prior to this but this magazine is put out by peers in the Pacific Northwest Underwater Photographic Society.  The calibre of these underwater photographers humbles me, so it is a really big deal!  

Please check out the write-up and my photos in Pacific Northwest Diver at this link. 

The direct link to the e-magazine is right under my dolphin cover shot. Ooh, an additional draw for you to go to the website – the promise of a dolphin photo! 

You can subscribe there too. 

My huge thanks to editor Dan Clements for the honour, the opportunity to expand the reach of The Marine Detective, and this additional push to keep me going.

My huge thanks to you for giving me further reason to believe these efforts are worthwhile.  

Clap! Clap!  Giggle! Giggle! 

The Marine Detective honoured to be the “Featured Photographer” in Pacific Northwest Diver.

When a Giant Falls . . . and people care.

© 2012 Caitlin Birdsall

This photo is of the juvenile male humpback whale that died in the early morning hours of June 12th on a beach in White Rock (some 40 km south of Vancouver).

Fellow Marine Education Research Society (MERS) director, Caitlin Birdsall was on site in her capacity with the British Columbia Cetacean Sightings Network and I have been haunted by her photos ever since she shared them with me.

While the images stir deep despair, they are also achingly beautiful and fill me with a great depth of hope.

People cared enough to place flowers on the deceased little whale.

People cared enough to stand in awe and respect.

People  . . . cared.

With this little whale dying on a beach in an urban centre, great public concern and national media attention were attracted, creating a potent opportunity for education.

The death of this whale illuminates how little we know about marine life, even the ocean’s giants.

Had anyone seen the whale before?  To date, no one has been able to identify this whale as an individual and thereby determine where he might have come from. We at MERS were not able to find this whale in our catalogue nor in that of the Department of Fisheries and Oceans.

How did the whale die?  The whale had an excruciatingly slow death from starvation due to entanglement in fishing gear. The gear had lacerated into the whale’s skin and had cut deep into the whale’s mouth. Ultimately, the young emaciated humpback became stuck on the beach at low tide and died there.

What type of fishing gear killed the whale? Fishing gear that was unfamiliar to local experts. Scott Landry, from the Provincetown Centre for Coastal Studies in Massachusetts, is one of the world’s foremost experts on entanglement and he shared with MERS director Christie McMillan that the line was very likely from offshore longline fisheries and was more difficult to recognize because the hooks had been in the water so long, they had corroded off the lines. Let’s truly absorb that for a moment – the whale may have been entangled so long that he outlasted the hooks on the fishing line.

Do humpback whales get entangled often? Entanglement is identified as a threat in the Recovery Strategy for the North Pacific Humpback Whale in Canada but the threat is very poorly understood.  Therefore, we at the Marine Education and Research Society have undertaken an entanglement scar study to determine how often humpback whale entanglement might occur. British Columbia’s vast coastline and relatively new Marine Mammal Response Network unquestionably lead to many undetected and unreported entanglements. Even in the Gulf of Maine where there is a well-established reporting network, studies have determined that less than 10% of large whale entanglements are witnessed or reported and only a fraction of deaths are detected. Scar studies in Southeast Alaska suggest that up to 78% of humpbacks are entangled at some point in their lives.

Are there solutions?  Humpback whales of the North Pacific must continue to receive protection under the Species at Risk Act. They are currently listed as “Threatened” but a 2011 assessment suggests they could be down-listed to being of “Special Concern”.  This is premature. Not enough is known about the population structure of the North Pacific humpbacks, let alone about threats such as entanglement.  With a better understanding of the incidence of entanglement, fisheries regulations could be adapted including gear modifications that allow nets and lines to break-away.

But the lessons here go beyond those relating specifically to humpbacks and to entanglement.

This “case” of an unidentified juvenile humpback dying in on a beach in an urban centre after months of agony, undetected and unreported, testifies to how little we know about our oceans and how easy it is to kill a giant, even with a bit of stray human-made fishing line.

The key to saving whales and the ecosystems for which they are ambassadors, is to retain the humility and connectedness we feel when we see pictures like this, letting it impact our consumer and electoral choices and our value systems.  We too often act as if we know it all; that we will be able to “manage” even unknown human impacts; and therefore, we relentlessly assault the oceans in favour of short-term economies.

Thanks to the efforts of many volunteers, coordinated by Jim and Mary Borrowman, this little humpback’s skeleton will come to hang in Telegraph Cove’s Whale Interpretive Centre. Maybe the powerful photograph will hang life-size behind it, adding to the potential of this whale’s death leading to some sort of positive gain for the environment and therefore . . . for ourselves.

For You For Oceans Day – for you love her as I do.

Dear “The Marine Detective” Community,

An Ocean Day reflection for you. 

If you can’t read the text, please click the image to enlarge.

May we continue to work together to raise awareness about the great beauty and importance of our Ocean. For life on land cannot survive without the Ocean. The Ocean is the “circulatory, respiratory, and reproductive organs of our planet” (from “The Fate of the Ocean” by Julia Whitty).

The Ocean produces about half of the oxygen we breathe. It feeds us and helps regulate climate by absorbing roughly 30% of carbon dioxide emissions and about 90% of the excess heat generated by greenhouse gases.

We depend on her for transportation, food, water, disposal, recreation, energy, oxygen, climate regulation and … inspiration.

Happy, healthy Ocean Day to you.

Blacked Out – June 4, 2012

“Speak out in defence of two core Canadian values: Nature and Democracy”. See http://www.blackoutspeakout.ca

As a very wise man recently said, I too am “profoundly disturbed by the current political atmosphere.”

From where I sit, I see steamrollers coming in, clearing the way for short-term economic gain by systematically eliminating the environmental checks and balances that safeguard the health of Canada’s environment.  Environmental regulation is being weakened; scientific research is being silenced or eliminated; and the activities of environmental non-profits are being thwarted. 

For example:

  • Bill C-38 is a 452 page “budget implementation bill” which amends more than 60 diverse social and environmental acts including gutting the Canada’s Fisheries Act, undermining the Species at Risk Act, and repealing the Canadian Environmental Assessment Act. Ecojustice references this as “the most far-reaching and devolutionary reform of federal environmental governance attempted in any one bill ever”. See their analysis of the top environmental concerns of Bill C-38. The Bill also designates $8 million over the next two years to fund “education and compliance activities with respect to political activities by charities” – charities that Natural Resources Minister Joe Oliver has referenced as “environmental and other radical groups”. 
  • Bill 37, the B.C. Animal Health Act, has now been withdrawn due to public outrage but this appears to have been an attempt to prevent the public release of information related to disease outbreaks like infectious salmon anemia. The Act contained the language that “a person must refuse, despite the Freedom of Information and Protection of Privacy Act, to disclose . . . information that would reveal that a notifiable or reportable disease is or may be present in a specific place”. Furthermore, the Act would have made the reporting on such outbreaks punishable by fines of up to $75,000 and two years in prison.
  • Despite the knowledge that marine organisms will testify to the effects of chemical pollution first, 75 scientists are to be laid off from Canada’s ocean contaminants program. This will leave only 5 junior scientists to do ocean contaminants research in the country with more coastline than any other in the world.  In the words of Dr. Peter Ross, who is world renown for his work on the bioaccumulation of contaminants in killer whales, this move by government qualifies as a “wholesale axing of pollution research” in Canada. 

This is why I supported the BlackOutSpeakOut campaign on June 4th, 2012, wanting to do what I can to provide a powerful signal to government that we, the keepers of paradise, will not allow short-term economic “growth” to be at the cost of long-term environmental devastation.

Of Sea Whips and Sea Pens

[Last updated November 15, 2023]
This blog is about Sea Whips and Orange Sea Pens, the predators that stalk them, and how they can defend themselves.

These are the most surreal-looking organisms. Both species are octocorals – colonies of 8-tentacled polyp-like animals. The polyps filter feed on plankton.

Sea Whips can reach a height of 2.5 meters (Balticina willemoesi).
Close-up on the feeding polyps of a Sea Whip.
Orange Sea Pens can be up to 48 cm tall (Ptilosarcus gurney).
Close-up on the feeding polyps of an Orange Sea Pen.

Information on Orange Sea Pens from the Monterey Bay AquariumA graceful creature of the seafloor, this sea pen resembles a plump, old-fashioned quill pen. Its colors range from dark orange to yellow to white. Each sea pen is a colony of polyps (small anemonelike individuals) working together for the survival of the whole. The primary polyp loses its tentacles and becomes the stalk of the sea pen, with a bulb at its base—the bulb anchors the sea pen in the muddy or sandy bottom. The various secondary polyps form the sea pen’s “branches” and have specialized functions. Some polyps feed by using nematocysts to catch plankton; some polyps reproduce; and some force water in and out of canals that ventilate the colony.”

Orange Sea Pen Defences

When confronted by sea star and nudibranch predators, Orange Sea Pens can:

1) Deflate, “shrinking” down and into the sand.
2) Inflate, to drift away.
3) Create bioluminescence – making a greenish-blue light that is assumed to somehow deter predators.
4) Produce a toxin but this is poorly understood.

And you thought humans were special! 😉

Deflated and retracted Orange Sea Pen. This can happen within about a minute of first contact from the predator (Wyeth & Willows, 2006 ). From “A Snail’s Odyssey: “A sea pen withdrawn into the sediment does not necessarily mean that it has been attacked or otherwise stimulated.  Studies in Puget Sound, Washington show that sea pens Ptilosarcus gurneyi may inflate and deflate several times a day, and at any given time as few as one-quarter of all individuals are up and feeding.”

From the excellent blog from the Washington State Department of Ecology:

“The orange sea pen is surprisingly mobile, inflating its siphonozooids with water and drifting like a leaf on the wind when it wants to relocate. It can also deflate, partially retracting into its fleshy base when predators come calling. The amount of retraction has been shown to be specific to the approaching predator, which suggests that the pen can actually sense who is creeping up on it . . . Young sea pens are especially vulnerable to predation. They are incredibly slow-growing, taking over a year to reach about an inch tall. Orange Sea Pens increase their chances of survival with sheer numbers — a single pen can produce about a million eggs during its 10-year lifetime.”

Orange Sea Pen having a bad day?  There are 4 predators here and it looks like the Orange Sea Pen was trying to inflate and drift away! But, there was a LOT of current whereby it kept being pushed down. Predators here are a Vermillion Star, two Diamondback Nudibranchs and one Orange Peel Nudibranch.

Diamondback Nudibranch approaches its prey, the Orange Sea Pen. From the Washington State Department of Ecology: “The rows of feeding polyps on the feather-like structures “wave their 8 tentacles in the water to catch drifting plankton. These polyps [are] also responsible for producing eggs and sperm that get released into the water column. The siphonozooids, or pumping polyps, are found in the orange regions on the sides of the rachis [central stalk]. Their function is to take in or expel water, allowing the colony to inflate or deflate.”

The following BBC video below is from southwest Tasmania in Australia. This is not the sea pen species found in British Columbia. However, I have included it as it shows, with time-lapse photography, how sea pens can deflate and retract in response to predation attempts by nudibranchs.


Diamondback Nudibranch approaching and a White Sea Pen (Virgularia sp to 30 cm tall).



Note that I found very little information about the anti-predator responses of Sea Whips. From Malecha and Stone, 2009:

“For those colonies lying on the seafloor, most of the peduncles and the tissues of the rachis below the polyps (approximately 15 cm) were generally not consumed by Tritonia diomedea. Additionally, predation by nudibranchs on erect Halipteris willemoesi [now Balticina willemoesi ] in the abraded and control groups did not occur. The disinclination of T. diomedea to prey on the lower portion of sea whips lying on the seafloor and their inability to prey on erect colonies perhaps suggests that H. willemoesi [Balticina willemoesi ] may have structural and/or chemical defenses on the tissue above their peduncles that deter epibenthic predators. Typically, chemical defenses are concentrated at the distal portions of colonies where polyp density is greatest, whereas structural defenses are often concentrated near the base of colonies (Harvell & Fenical 1989, Wylie & Paul 1989). The distribution of defenses is perhaps an adaptation to various types of predators and their mode of attack. Therefore, if sea whips have evolved defensive structures located at the base of the colony that are specific to epibenthic, non-swimming predators such as nudibranchs and sea stars, the defenses certainly do not provide protection when sea whips are not erect. Disturbed animals, especially those lying on the seafloor, may be more vulnerable to predation from a wider array of predators since the defenses at their polyps may not be adaptively effective against non-swimming predators. Further study could examine the possible chemical and/or structural defenses of sea whips that are common among octocorals.”

Very Rare Fish Find: King-of-the-Salmon (Trachipterus altivelis)

Last updated 2026-01-09
The original post below was about a sighting of this species in Port McNeill in 2012. The blog has since been updated with additional sightings and details (including video about the species astounding feeding adaptations).

King-of-the-Salmon at ~1.5m long. Photo: September 2017 by Collin Jay Johnson; near Tattoosh off Neah Bay Washington; depth ~100 fathoms (180 m).

See below for the extraordinary feeding method of the King-of-the-Salmon by which they extend their jaw. This member of the ribbonfish family belongs off our coast. To date I have not been able to verify if the origin of the name of the species is indeed from Makah legend. 


Here’s a finding to enhance your sense of wonder about the sea and how little we know about its inhabitants.

On March 23rd, 2012 Darren and Joanne Rowsell found this dead specimen on the beach at Lady Ellen Point, Port McNeill, British Columbia, Canada. When the photos landed in my inbox, I almost fell off my chair recognizing how rare a find this was. It’s a King-of-the-Salmon (Trachipterus altivelis). The adults feed in the open ocean at depths of 900+ m (3,000 feet) so they hardly ever wash ashore and I had never seen one before.

The King-of-the-Salmon belongs to the ribbonfish family (Trachipteridae). You’ll note from Joanne’s photos that the species is indeed very ribbon-like. It is extremely thin and maximum confirmed length is 2.45m (Savinykh and Baitalyuk. 2011). The long, high, crimson coloured dorsal fin is also very reminiscent of a ribbon, tapering down the full length of the fish’s back. These fish move in a snake-like fashion, undulating their long bodies.

The unique common name of the King-of-the-Salmon is said to originate from Makah First Nation legend. The legend is said to be that the fish was believed to be the “king” that would lead salmon back to their rivers to spawn and that to kill one was believed to bring bad luck, causing the death of the salmon.  The Makah, like other fisherfolk, must occasionally have caught one on their lines or in their nets. HOWEVER, I have never been able to verify if this is indeed a Makah legend.

Range:

The species’ range is believed to be from the Gulf of Alaska to Chile.

Diet and Feeding Method:

Smaller King-of-the-Salmon do feed closer to shore and their diet is known to include copepods, annelid worms, fish scales, and fish larvae. Larger individuals feed on copepods, krill (euphausids), polychaetes (bristle worms, small pelagic fish, young rockfish, squid, and octopus.  Part of what makes the species so unique is that they can capture (and process prey) by extreme protrusion of the upper jaw. See photos below.

From Ferry, et al (notably the ONLY research I could find on this species): “T. altivelis does appear to have earned the title of “most extreme”in terms of premaxillary protrusion. The distance to which the upper jaw is protruded anteriorly away from the head exceeds that of any other known species  . . .the gut was examined in an attempt to gain further insight into this speciesecology. The gut was empty, but the anatomy was unusual and potentially suggestive of extreme foraging habits. There were hundreds of very small diverticuli lining the gut, which suggest to us a mechanism for increasing digestive surface area and/or efficacy. This species has been described as a deep-midwater forager on crustacean zooplankton (Hart, 1973; Shenker, 1983), which is consistent with such mechanisms.”

Predation:

I presume that stomach content studies have allowed science to determine that the predators of the King-of-the-Salmon include the Bigeye Thresher Shark (Alopias superciloosus), and the Longnose Lancetfish (Alepisaurus ferox).

Swimming: 

From Dr. Gavin Hanke of the Royal BC Museum: “King-of-the-Salmon swim by passing a sine wave down their dorsal fin – they can get a fair bit of speed just by doing that. They can also reverse using the same fin flutter. They slowly turn by putting a curve in the body. However, in the first few seconds of the linked video you can see that they also swim in a more typical fishy way (using eel-like body oscillation) when they need a burst of speed or a really quick turn.” See video below of one swimming.



And THAT appears to be all that is known about the King-of-the-Salmon – yet another one of our remarkable marine neighbours.

From Ferry, et al (2019): ” While much work remains regarding the ecology of T. altivelisa nd its relatives, it is certain that this fish holds many surprises yet in store”. No doubt!

2021

May 12, 2021: King-of-the-Salmon washed up at Witty’s Lagoon near Mechosin documented by John Michael Thorne. 


2020

September 18, 2020: King-of-the-Salmon washed up at Whiffen Spit (Sooke) documented by Dana LeComte (photos below).

July 18, 2020: Live King-of-the-Salmon documented by Gary Bodine at Pillar Point, Washington. 

June 24, 2020: ~1.5 m long King-of-the-Salmon found struggling to stay upright by Al Champ and Wendy Cooper in East Sooke (photo below).

June 24, 2020 : ~1.5 m long King-of-the-Salmon in poor condition found by Al Champ and Wendy Cooper in East Sooke, across from the Sooke River. They strived to help it on its way but ran out of daylight, finding it was getting weaker and weaker and that it made no attempt to swim away.  

June 8, 2020: King-of-the-Salmon documented by Harbor WildWatch in Salt Creek, west of Port Angeles, Washington. They provided the insight that “We speculate that this individual swam too close to shore and was killed by the waves as there was no evidence of predation. These are thin delicate fish adapted to the deep ocean. The tide pushed it up into the creek where it was discovered.”


2019

Sighting of a King-of-the-Salmon August 19, 2019 (at least 70 cm long). Greg and Kim Ashton relayed how “We had just tied up our boat in the marina and were walking to shore when Kim spotted what at first we thought was an eel, but quickly realized it wasn’t but some type of fish we had never seen before. It was in five to six feet [~2m] of water and then swam up into shallower water . . . I was amazed at how it seemed to be looking at us and how brightly colored chrome-like its body was . . .”. Video of this individual (below) reveals this individual may not have been healthy.

2017

Otoliths / Ear Bones

Photo above and the following information was shared by Micah Quindazzi who is a masters student at the University of Victoria studying the King-of-the-Salmon. He extracted the ear bones (otoliths) of two full-grown adult King-of-the-Salmon (the September 18, 2020 and February 6, 2019 individuals). The photo shows the left and right otoliths from the September 18th individual. He shared that it is notable that the otoliths are tiny in comparison to the body size of the fish.

“R” We Getting It? Reflections for Earth Day – April 22nd

Earthling design by Kitty Chan. The "Earthlings" were a school environmental group I had the joy of working with in the 1990s in Rotterdam. Kitty allowed me to use this as the logo for my company "Earthling Entreprises".

Reduce, Reuse, Recycle!

Reduce, Reuse, Recycle!

Like automatons we can chant out this slogan when asked what we can for environmental good, so successfully ingrained is the motto believed to date back to the first Earth Day on April 22nd, 1970. For many of us, the chanting is accompanied by visions of blue boxes and the logo with 3 arrows.

Is this good, or bad?

It is of course good that the solution for reducing waste is so well known. That the solution can be captured in just 3 words also certainly makes the point that it’s pretty simple to live more sustainably.

Except, something got lost along the way.

It is not Reduce, Reuse, Recycle.

It is REDUCE –> Reuse –> Recycle. The 3R slogan was born as the “waste hierarchy”. The 3 actions are not equal. “Reduce” is far, far more important than “Reuse” and the least impactful of the 3Rs is “Recycle”.

To use the case of the plastic water bottle to emphasize this, yes, you can recycle the bloody thing so it is not part of the legacy of plastics drifting and seeping around the planet BUT it shouldn’t even exist in the first place (at least in the developed world.) The tap water on northern Vancouver Island is of very high quality and by using it, you avoid the chemical and energy cost of the bottle being made, transported and . . . recycled.  If you have more urban tap-water, filtering can solve the issue of any taste you may not enjoy. 

Having the great privilege of working with children to help them feel empowered in a world with a lot of environmental gloom, I’ve polled them to find out what they believe to be the most important “R”. Almost always, the answer is “Recycle”.

Oops. This isn’t good. This really isn’t good. The shiny, most powerful, most hope-inspiring gem of environmental change has been misidentified. Striving to “Reduce” consumption of resources is the most powerful tool against all environmental problems; from waste management, to bioaccumulation and climate change. It is also the “R” that will give you the greatest bang for your buck – a buck you can cash in at the bank of happiness. Less misspent cash on disposable, nondurable and frivolous items and less wasted energy and other resources, means greater freedom from the consumer paradigm and a greater sense of hope for the future.

Earthling design by Kitty Chan.

How is that the most powerful “R” has become misidentified and that the whole concept of the 3R hierarchy has become lost? Is it because recycling is something tangible where it is difficult to visualize the action of “reducing”? I would argue that this should not be the case. 

“Reducing” should be the great green common denominator.

To use some examples applicable to teaching: we are leaving half the lights off in the classroom to use LESS energy; please use the paper in the recycling bin so we use LESS paper; close the door so we waste LESS heat; and how wonderful that you are using a reusable container for your lunch so there are LESS baggies bulging from school garbage cans and swirling around school yards. You get the idea.

Is it then because recycling allows us to have our plastic wrapped cake and eat it too? Certainly this is how the oh-so-powerful and oppressive consumer paradigm wishes to manipulate us i.e. “We’ll green-up making you feel less consumer guilt, but you’ve got to keep buying in the volume to which we’ve become accustomed”.

Or, are there many of us that don’t really believe how essential it is to get our act together for future generations and that by recycling we deliver an act of appeasement, just in case?

If you have read this far, thank you, for you are a significant player in creating positive environmental change. That’s the irony of writing an item such as this – it won’t reach the audience that needs to change the most; those who do not even recycle.

You care enough to want to refine what it is you already do.

Know that this is not about being perfect. It is about ensuring that our efforts have the greatest net gain and that we recognize the power that lies in “Reduce”.

Simply stated, less is more – more positive impact; more financial liberty; and more empowered, shiny-eyed, happy and healthy children in a future we cannot see.*

Buffalos Mating . . . Underwater!

Last updated: March 27, 2026

That’s right, it’s mating season for buffalos   . . .  Buffalo SCULPINS that is!

Now that I’ve lured you to this posting with the procreation of a huge, shaggy terrestrial mammal on your mind  . . . let me show you the spawn of this wondrous fish.

The Buffalo Sculpin –  Enophrys bison – has earned the association with buffalo/bison due to the horn-like spine found on each gill plate (operculum). The species can be up to 37 cm long.

As is the case for many species in the sculpin family, male Buffalo Sculpins guard the eggs from predators. They also fan the fertilized eggs with their pectoral fins to aerate them and stop growth of algae / bacteria.  Sometimes they guard the eggs laid by multiple females (see below for a male that appeared to be trying to guard EIGHT egg masses). When you consider that a female can lay between 19,000 and 32,000 eggs, the males have a lot of fertilizing and guarding work to do!  Their guard duty lasts 5 to 6 weeks until the eggs hatch. 

Another male guarding eggs. If you look carefully, you will see the horn-like spines on the fish’s right gill plate. It is these horn-shaped gill protrusions that led to this species getting both its scientific and common name. ©Jackie Hildering.

Many of the photos below show how you the males lie with their flat heads directly upon a cascade of eggs. The clusters of eggs laid in the spring allow me to find this incredibly camouflaged fish much more easily than I normally could. When I see a golden, orange or greenish shiny mass of eggs, I know a male Buffalo Sculpin has to be very near by. The bright colour of the eggs suggests that they might be toxic to many species, further protecting them from predation. 

Very interestingly too, there is a species of fish known to parasitize on the care provided to the fertilized eggs by Buffalo Sculpins. Spinynose Sculpins (Asemichthys taylori)  will lay their eggs on top of the Buffalo Sculpin eggs. The Spinynose Sculpin eggs will hatch faster and it is even possible that the presence of their eggs slows the development of the Buffalo Sculpin eggs. This “nesting parasitism”, is a “behavior previously unknown among marine fishes.” (Kent, Fisher, & Marliave, 2011).

As you can see, Buffalo Sculpins’ red, brown and pink colouration makes them very difficult to discern from the similarly brilliantly coloured life around them.  They will remain absolutely still so as not to give away their presence. Their relative, the Red Irish Lord, has the same survival strategy. (See this previous blog item for photos and information on the Red Irish Lord.)

Same male as in the photo above. Egg masses are numbered in the image.

The camouflage, in addition to reducing the risk of predation by bigger fish and seals, allows the Buffalo Sculpin to be a very successful ambush hunter of shrimp, crabs, amphipods and small fish. It has been suggested that they eat mainly algae since this has often been found in their gut.

I had speculated in the original version of this blog that the algae may end up in their stomachs as a result of Buffalo Sculpins grabbing prey ON the algae! But Greg Jensen provided the feedback that they had done experiments that found that adult Buffalo Sculpin eat Sea Lettuce (Ulva). He emphasized that despite the great abundance and diversity of algae in the Northeast Pacific Ocean, there are very few fish that are known to eat it – just Buffalo Sculpins and some prickleback species (Source: Gregory C. Jensen, personal communication, March 25, 2026).
