Recently, I noticed a lot of splashing in a tideline off Telegraph Cove, BC. I share my observations with you via the little video clip at the link below.
You’ll note that it looks like big rain drops are hitting the water.
I discovered that what was creating the splashing were juvenile yellow-tail rockfish feeding on zooplankton. The zooplankton, including a small species of krill, had been concentrated at the surface by the big tidal exchange. There had been almost a 4 metre exchange between high and low tide (more than 12 feet).
I also discovered a very unique larval fish in the tideline that day but will share that discovery in a future “The Marine Detective”.
