Temporal and spatial dynamics of the Northern Cod stock

The Northern Cod Acoustic Telemetry (NCAT) project in collaboration with the Association of Seafood Producers (ASP) and the Atlantic Groundfish Council (AGC) aims to fill gaps in our knowledge of the Northern Cod stock via the use of genomics and telemetry. Within the genomic component, our goal is to compare the genomic composition of cod tissue samples collected in the 1990s, when the stock collapsed, to cod collections from the late 2010s, to evaluate changes in the genetic diversity and structure of the stock and to identify regions in the genome that might be differentiating cod exhibiting different life history traits. The telemetry component entails analyzing detection data of >700 cod individuals which have been implanted with an acoustic tag. Detections are being found by multiple inshore and offshore receivers along the coast of Newfoundland and Labrador. This analysis will provide information about cod distribution, movements, and habitat preferences.
