More high-seas surveys needed to understand what's happening with Pacific salmon stocks: fisheries scientist

Massive changes in the Pacific Ocean’s ecosystem in recent years are affecting salmon in ways never seen before, says a Nanaimo-based fisheries scientist.

“Then in 2023, we saw almost record catches again — huge returns with pink salmon throughout the Pacific and Russia. In Alaska and even in B.C., we got good catches.” “To do that, you need to understand more about what regulates salmon. We really know relatively little about the ocean life of salmon.”

The society said that these expeditions “provided new insights to the mechanisms regulating salmon production and their winter ecology in the North Pacific Ocean,” and also proved the “indisputable” need for international co-operation to study salmon in such a wide and diverse habitat. “We really need to continue this. There’s no better example than what happened this year with huge returns of pink salmon throughout the North Pacific.”

If that happens in 2024, “it’s really clear evidence that the solutions, the understanding of what’s going on is really an international problem.”
