Join me in the cold, dark, life-sustaining NE Pacific Ocean to discover the great beauty, mystery and fragility hidden there.

Very Rare Fish Find: King-Of-The-Salmon (Trachipterus altivelis)

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 originates from Makah First Nation legend. This fish was believed to be the “king” that would lead salmon back to their rivers to spawn.

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.

When one of these very rare and unique fish does wash ashore, it usually draws a lot of attention. See the video and photo below for a large King-of-the-Salmon found near Oak Bay, British Columbia on September 21st, 2017. A second one was also found near Oak Bay a few days later on September 26th. And a third was found on a beach off Hood Canal, Washington on October 3rd, 2017. (See photos below).

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

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), small pelagic fish, young rockfish, squid, and octopus. 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).

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

1.8 m long female King-of-the-Salmon found on October 3rd, 2017 off Hood Canal, Washington by Chris and Randi Jones. As relayed to Randi by Dayv Lowry of the Washington Department of Fish and Wildlife “this is the first reported occurrence of this species in Hood Canal ever, and the only other one found in Puget Sound was discovered on a beach back in the 1990s near Tacoma.”

    I believe deep sea trollers pull these up every so often, I too have seen pictures of these rare beasts. Great to get some background info on why they are called King of the Salmon.

    Enormous eyes correlate well with life in in dark waters. Wonder if it makes vertical migrations as some ribbonfish do.

    My Dad was on a reefnet gear on Lopez island they caught one 6 foot long. 5 lbs in 1958. I have a poloroid picture, but it is in bad shape.
