Hatchery Fish Often Fail in the Wild. Now We Might Know Why

December 23, 2017 Canada, Marine Science, Pacific

Wild salmon are struggling to get their groove back.,, For years, Canada has tried to help bolster the salmon population by releasing hatchery-raised juvenile fish, or smolts, into the wild. Scientists know these hatchery smolts don’t do well in the wild—the fish tend to die younger than their wild brethren and reproduce less, but it’s unclear why. In a recent study, however, researchers think they’ve hit upon a possible explanation.,, In Washington State, hatchery-spawned steelhead also do poorly in the wild. click here to read the story 12:31

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.
