Letter: Taking stock of cod stock assessments

May 21, 2017 Canada, Letters, Marine Science

In a Telegram letter published May 6, (“Perfectly good fisheries data being ignored,” click here ) Harvey Jarvis criticized the Department of Fisheries and Oceans’ assessments of northern cod and 3Ps (i.e. south coast) cod. Based on my 20-plus years of experience with stock assessments in Newfoundland and Labrador and other regions (Canada, the U.S., and Europe), I think Jarvis is absolutely correct about the 3Ps cod assessment, but he is incorrect about the new northern cod assessment framework that DFO adopted in 2016. Jarvis suggested that the only information used in the northern cod assessment model to estimate stock biomass is the DFO research vessel survey index. He indicated that the commercial catch, the commercial logbook data and the cod sentinel catch rate indices are not used. This is not true. The 2016 northern cod stock assessment used a state-of-the-art model,,, click here to read the letter 17:23

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.
