veni, vidi, fishi
Thanks, Steve!Hi Jake,
I do not know if there have been specific studies of the diet of fish caught off Oregon and Washington specifically during the late summer fishery. But there have been investigations of their diet from California (with some Oregon and Washington) and the Southeast Pacific. Based on the "number of prey items" data from fish off the West Coast, various squid species comprise approximately 11% of the diet. Crustaceans as a group form 48% of the diet with krill alone forming 26% and pelagic sergestid shrimp at 15%. Fish overall form 41% of the items in the diet with anchovies at 25%.
These are summaries which lack nuances of seasonality or location. Nick may have a much better idea of what he has encountered off the Washington coast during the late summer fishery. The data indicate that albacore are generalist predators. Unlike a trout that might become fixated on a specific hatch, I suspect that albacore are much more opportunistic.
