Fixed gear sentinel fisheries program - northern Gulf of St. Lawrence

Fixed gear sentinel fisheries program - northern Gulf of St. Lawrence In place since 1994 in eastern Canada, the sentinel fisheries program is the result of a collaboration between Fisheries and Oceans Canada (DFO) and commercial fishermen. Under this program, contracts are awarded by tender to fishermen to carry out fishing activities according to scientific protocols developed by DFO. Description of fixed surveys The fixed gear sentinel fisheries of the northern Gulf of St. Lawrence are conducted in the divisions 4R, 4S and 3Pn of the Northwest Atlantic Fisheries Organization (NAFO). The gear used is fixed gillnets or longlines. Fishing activities with nets must have a mesh size of 5 ½ inches (140mm) and are limited to a maximum of 12 to 20 nets depending on the region. Longline fishing activities, for its part, must be carried out with traditional J #16 or C #12 hooks and are limited to a maximum of 1000 hooks. Data For every fishing activity, the total catch is sorted and weighed by species. Biological data such as length, weight (sampled, per individual, gonad, liver and stomach), sex and maturity are then collected on a sub-sample of cod and Atlantic halibut.
