Hatchery misfits

February 23, 2019 North Pacific

Scientists studying pink salmon in Alaska’s Prince William Sound have come to a startling conclusion: Female hatchery fish gone feral reproduce at only about half the rate of their wild cousins. The finding, if confirmed by further studies, could have broad implications for the management of mixed stocks of wild and hatchery salmon. Why hatchery fish perform so poorly in their natural environment is unknown, Alaska Department of Fish and Game biologist Chris Habicht said Friday. The agency researcher cautioned, as well, that the latest finding is based on data from only one reproductive cycle. The dismal spawning success of hatchery fish during 2014-2016 could be a statistical anomaly. Future studies could find higher returns and even out the results when averaged over the years. >click to read<21:41

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. When it comes to the oceans it seems as if it’s about all that the industry connected mega-foundations that support the anti-fishing ENGOs with hundreds of millions of dollars a year in “donations” are interested in controlling.
