Abstract
A survey of the shallows around Sable Island on the Scotian Shelf in July-August 1982 confirmed the summer concentrations of juvenile haddock, Melanogrammus aeglefinus, which were evidence from a survey in August 1981. Comparison of the spatial distributions of juveniles showed some persistence of concentration of 0 group fish, but not of 1-group fish, both during two successive surveys in 1982 and from surveys in 1981 and 1982. Two 24-hr fishing experiments showed well-defined diel vertical migration in 0-group but not in 1-group haddock. Estimates of population size indicate reductions of about 46% for 0-group and 39% for 1-group fish from 1981 to 1982. The results from such surveys may be indicative of recruitment to the haddock stock on the central part of the Scotian Shelf.
