January 16, 2017 — PORTLAND, Maine — Seeking to end a long-running disagreement about exactly how many cod are left in the Gulf of Maine, federal scientists plan to outfit commercial fishermen with equipment used to establish groundfish quotas.
The fishermen tend to argue that there are more cod than the government realizes; therefore, the number they may legally catch should be higher. Government scientists counter that fishermen’s natural tendency to fish where they are most likely to catch large numbers leads them to overestimate the cod population in the entire Gulf of Maine.
By next year, the Northeast Fisheries Science Center hopes to begin outfitting commercial boats with surveying equipment and paying fishermen to pull in catches that will supplement the regular trawl surveys conducted by government scientists, according to Russell Brown, who heads the center’s population dynamics branch. The gathered data will be fed into the complex process used to set catch quotas.
It’s a collaboration that Brown hopes will give regulators a more detailed picture of the fish population and build trust among fishermen, who in turn see it as an opportunity to show the scientists what’s really going on.
For years, fishermen and scientists have clashed over how to properly estimate fish populations and set the catch quotas that rule the livelihoods of Maine fishermen. Fishermen suggest that scientists are missing fish and setting the quotas too low, while scientists say fishermen are missing the big picture. But both groups believe collaboration would be a positive step toward better protecting Maine’s fishing industry and environment, even as ocean waters warm.
“It’s really perplexing that you’ve got a set of federal scientists who are sampling the ocean methodically and coming up with a very different picture than the fishermen about what’s going on out in the Gulf of Maine,” Jonathan Labaree of the Gulf of Maine Research Institute said.
