Pollock (Pollachius virens) stock structure in the Canadian Maritimes inferred from mark-recapture studies
Abstract The current management unit for pollock on the Canadian Atlantic coast is large compared with other gadoid resources, and includes the Scotian Shelf, the Bay of Fundy, and the Canadian portion of Georges Bank. Based on an analysis of mark-recapture studies conducted in the Canadian Maritime...
