Stock delineation of redfish (Sebastes mentella) straddling NAFO (Subareas 0, 1, 2+3KLMNO) and NEAFC (ICES Subareas XII and XIV) areas based on genetic analyses of archived otoliths
How organic residues on ear stones help us to discriminate between different redfish stocks.
This project will provide the first description of the genetic structure of the redfish (Sebastes mentella) stocks straddling NAFO and NEAFC management areas. Specifically, this project will determine the degree of connectivity of redfish that reside in the Labrador Sea (NAFO 2+3K) and Newfoundland's Grand Banks (NAFO 3LN) with those in the Irminger Sea (ICES XII, XIV) and western Greenland (NAFO 1), as well as with redfish from Davis Strait (NAFO 0) and Flemish Cap (NAFO 3M), based on genetic analyses of archived otoliths. Secondary objective: The project will complement the genetic description of stock structure with shape analysis of the otoliths.
