Resident fish production, ecosystem carrying capacity and population dynamics of Atlantic cod (Gradus morhua) in Gilbert Bay, Labrador: a marine protected area
The Marine Protected Area in Gilbert Bay, Labrador was created mainly to protect its resident Atlantic cod (Gadus morhua) population, which is genetically distinguishable from other northern Atlantic cod populations. In order to effectively manage this population in the future, basic information reg...
