Resident orcas’ appetite likely reason for decline of big Chinook salmon

December 16, 2019 North Pacific, Pacific

“We have two protected species, resident killer whales and Chinook salmon, and we are trying to increase abundances of both—yet they are interacting as predator and prey,” said lead author Jan Ohlberger, a research scientist at the UW School of Aquatic and Fishery Sciences. “Killer whales don’t show a lot of interest in Chinook until they reach a certain size, and then they focus intensely on those individuals.”>click to read< 19:02

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing. Hence the term “overfished.” Hence the mandated knee jerk reaction of the fisheries managers to not enough fish; cut back on fishing. What of other factors? They don’t count. It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer.
