Annual multidisciplinary survey for assessing groundfish and shrimp in the Estuary and northern Gulf of St. Lawrence (CCGS Cabot 2022 - ongoing)

Fisheries and Oceans Canada (DFO) has conducted an annual multidisciplinary scientific survey using a bottom trawl in the Estuary and the northern Gulf of St. Lawrence during the summer since 1984. Over the years this survey has been conducted aboard four vessels: the MV Lady Hammond (1984-1990), the CCGS Alfred Needler (1990-2005), the CCGS Teleost (2004-2022) and the CCGS Cabot (2022-current). It is important to note that the objectives, the methods used and the identification of the species during these surveys have improved over time in response to DFO requests and mandates. The data are therefore not directly comparable between these surveys. However, comparative analyses have been carried out between vessels, and conversion factors are available upon request for a number of species. The specificities of the missions onboard the CCGS Cabot are described below. Objectives: Assess groundfish and northern shrimp population abundance and condition Assess environmental conditions Conduct a biodiversity inventory of benthic and demersal megafauna Assess phytoplankton and mesozooplankton abundance Monitor the pelagic ecosystem Collect samples for various research projects Survey…
