An examination of the factors affecting the sustainability of the Newfoundland & Labrador snow crab fishery
The Newfoundland and Labrador (NL) snow crab (Chionoecetes opilio) fishery has become the backbone of the fishing industry since the closure of the groundfish fishery in the early 1990's. In 2003, snow crab contributed approximately $277 million to the total landed value of the fishery. This re...
