Mobile Sentinel Fishery in Northern Gulf of St-Lawrence

This work is a useful component for the assessment of several groundfish stocks including the northern Gulf cod, Atlantic halibut, redfish and Greenland halibut (turbot). These surveys began in 1995 and have been conducted each July since that time. Although the sentinel program covers several components, the specifications here concern only the trawl surveys in fishing areas 4S and 4T (northern part). The survey’s main objective is to develop an independent abundance index for the fishery, which will ultimately be used for the annual adjustment of total allowable catches (TAC). The data from this program are available on the website of the St. Lawrence Global Observatory (SLGO): http://ogsl.ca/en/sentinel/data/fixed.html
