July 13, 2021 — The following was released by NOAA Fisheries:
The Gulf of Maine Cooperative Bottom Longline Survey has been conducted from two commercial fishing boats each spring and fall since 2014 by the science center’s Cooperative Research Branch. At each station environmental conditions are collected by sensors and a baited longline (1 nautical mile in length) is set and retrieved. Scientists then remove catch from the line and weigh, measure, and collect biological samples from the fish that come onboard.
Spiny dogfish, cusk, and haddock were the largest components of the catch, consistent with what has been seen in earlier surveys. Other species commonly caught included thorny skate, Atlantic cod, barndoor skate, white hake, and red hake. This season we also caught 17 Atlantic wolffish and seven Atlantic halibut. Both species are considered “data-poor” in terms of stock assessments. Staff also observed multiple instances of porbeagle sharks eating fish off the line.
