Assessment of Northumberland Strait scallop stocks - 1981 / by G.S. Jamieson, G. Robert, and M.J. Lundy.: Fs70-8/81-72E-PDF

"Spring and summer scallop landings in the Northumberland Strait during 1981 were 95% greater than in 1980. Landed price increased by 20%, resulting in the entry of many previously inactive, but licensed fisherman into the fishery. Average CPUE changed by +16, -6 and -13% in the eastern, central and western Northumberland Strait respectively, while the number of active fishermen increased by 71, 78 and 2% from 1980 levels. The closed fishing zone for scallop established in June, 1980, was removed before the 1981 fishery. Reductions in some allowable meat counts were introduced, but because meat counts only regulate scallop size at exploitation, no effective conservation of scallops at a high density per unit area was achieved. Extensive mortality of prerecruits has occurred in the western Strait, heightening concern for the visibility of the scallop fishery in this area of the foreseeable future"--Abstract.
