Cod Cannibalism: With natural prey like capelin and shrimp in decline, cod are eating their young

May 6, 2020 Canada, International News, Marine Science

Stalled. That’s how research scientist Karen Dwyer of the Department of Fisheries and Oceans describes the northern cod stock following this year’s assessment. Ecosystem conditions appear to be the main factor, said Dwyer — especially low stocks of capelin and shrimp. “Both of those prey are very important in driving the population dynamics for cod,” she said. While there’s been an increase in different types of zooplankton, Dwyer said, there’s been a decrease in fatty zooplankton. “There used to be large numbers of large fatty zooplankton, full of fat, which are really good for young fish to eat, young fish such as capelin or even young cod,” she said. “Over time they’ve seen a decline in these large fatty zooplankton.” >click to read< 07:18

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.
