"A two-phase survey for northern shrimp was conducted in the Hopedale and Cartwright channels off Labrador during the summer of 1987. The methodology, described by Francis (1984), proved useful in allowing flexibility in the allocation of fishing stations to better reflect current shrimp distribution. Variance was substantially reduced in the final biomass estimates, compared to the results obtained from Phase 1 of the survey, alone, while the mean values were similar. Problems associated with the diel variation in shrimp catches were not solved, however, by this method. The design is briefly described as well as its application in the 1987 research survey in both areas"--Abstract, page 2. Includes abstract and series statement in French.
