註釋

An exploratory snow crab fishery was initiated in Bay of Islands on the western coast of Newfoundland in 1987. Since the beginning of the fishery, it has been managed under no quota limitations. From 1987-91, landings were less than 15 tonnes per year but in 1992, landings increased to 199 tonnes, although the fishery had to be closed a number of times because of the high incidence of soft-shelled crab in the catches. For the first time in 1992, a post-season trawl survey was conducted to evaluate the available biomass and provide scientific advice for the establishment of a sound management plan. The survey sampled 25 stations during the day time using a 25 meter otter trawl.
