PURPOSE: Determine the stock status of southern Gulf of St. Lawrence Atlantic Cod. DESCRIPTION: The yearly spawning stock biomass estimates of southern Gulf of St. Lawrence Atlantic Cod were obtained using a Statistical Catch-at-Age model as part of the stock assessment to year 2023. The...

Salmon escapement data constitute important corporate knowledge which must be adequately maintained and accessible. The Salmon Escapement Database (NuSEDS) is the DFO Pacific Region’s central database that stores individual spawner survey data records, spawner abundance estimates and the linkages...

PURPOSE: Determine the stock status of Gulf of St. Lawrence Witch Flounder. DESCRIPTION: The yearly biomass estimates of Gulf of St. Lawrence Witch Flounder were obtained using a Bayesian Schaefer Surplus Production model as part of the stock assessment to year 2021. The yearly estimates...

This dataset contains observations of species occurrences from seafloor imagery collected by the remotely operated underwater vehicle (ROV) during the 2012 Expedition to Cobb Seamount. The ROV operated by Fisheries and Oceans Canada was a customized Deep Ocean Engineering Phantom HD2+2 which...

This dataset contains observations of species occurrences from seafloor imagery collected by the autonomous underwater vehicle (AUV) during the 2012 Expedition to Cobb Seamount. The National Oceanographic and Atmospheric Administration-operated SeaBED-class AUV which collected photographic images...

PURPOSE: The research survey provides a fisheries-independent source of information about all marine living organisms that are captured by the fishing trawl used to obtain samples in the southern Gulf of St. Lawrence. DESCRIPTION: Tow, catch, length frequency, and biological information for...

PURPOSE: In this study, we examined the structure and function of the Southampton Island marine food web across 149 species of benthic and pelagic invertebrates, fishes, marine mammals and seabirds collected from 2016 to 2019, to provide a baseline for future studies that aim to quantify...

PURPOSE: The primary objective of this survey is to obtain an index of the abundance of American lobster (Homarus Americanus) in the Northumberland Strait. This research survey also provides fisheries-independent information for all of the species captured by the trawl. DESCRIPTION: Catch...

A Conservation Unit (CU) is a group of wild Pacific salmon sufficiently isolated from other groups that, if extirpated, is very unlikely to recolonize naturally within an acceptable timeframe, such as a human lifetime or a specified number of salmon generations. Holtby and Ciruna (2007)...
