Atlantic Halibut

The Atlantic Halibut resource in the Gulf of St. Lawrence has increased dramatically in recent years. The Atlantic Halibut tagging is used to collect reliable scientific data to ensure we maximize the return to harvesters and their communities without impeding growth in the stock.

Information collected: halibut distribution, migration, growth rate and condition. Biological samples (i.e. otoliths, gonads, etc.) from both commercial and sub-commercial sized fish are collected.  Information collected through the tagging will be used in the scientific assessment process.

The total number of Atlantic Halibut tagged in the Northern Gulf of St. Lawrence is 7,559.

Dr. Erin Carruthers

Dr. Erin Carruthers is the Science Director and Senior Fisheries Scientist with the Fish, Food and Allied Workers Union (FFAW-Unifor), which is the labour union that represents the owner-operator fleet in Newfoundland and Labrador. The FFAW is committed to research and management that supports healthy oceans, fisheries, and coastal communities. Dr. Carruthers received her Ph. D. in Biology from Memorial University in 2011 followed by a postdoctoral fellowship with the Centre for Fisheries Ecosystems Research. Before coming to Newfoundland, Erin worked as a Research Biologist with Fisheries and Oceans Canada at the St. Andrews Biological Station. Her current research program is co-constructed with fish harvesters and includes research on coastal fishing communities, collaborative longline and trap surveys, and best practices for the avoidance, handling and release of unwanted catch.
