June 2, 2016 โ BOWDOIN, Maine โ Proper stock assessments are the key to sound fisheries management here in New England. The current and now primarily survey-based assessments are heavy with uncertainty and always assumed to be overstated. Given the changes in the available stock assessment data created by 20 years of regulations, the uncertainty only seems to be increasing.
The fact that the R/V Bigelow, the National Oceanic and Atmospheric Administrationโs primary fishery research vessel, delayed the survey this year is a significant threat to fishermen: We have been told that there are very few codfish in the Gulf of Maine, but this spring, fishermen have found it impossible to set a net in the water without catching codfish. This does not correlate well with the assessment advice.
Many boats have simply tied up to avoid codfish. The late start taken by the survey cruise has most likely missed significant codfish โdataโ as the research vessel remained at the dock.
Even with an on-time start, the survey method employed by the R/V Bigelow covers only a tiny sliver of the available fishing bottom and puts the survey gear on the bottom for a very short time during trips made in the spring and fall. The R/V Bigelow has also become famous in the fishing community for its demonstrated inability to catch cod and flatfish alongside commercial vessels catching those species and in areas fishing boats declared off limits to themselves because of the presence of codfish.
The low annual catch limit for codfish is tied directly to the low numbers provided by the most recent stock assessments. The low limit has resulted in small codfish allocations to each commercial fishing boat. Once a boat harvests its cod allocation, it will be prohibited from fishing for the duration of the fishing year even if it has significant allocation of other species.
