Effects of site and season on movement frequencies and displacement patterns of juvenile sea scallops Placopecten magellanicus under natural hydrodynamic conditions in Nova Scotia, Canada

There was a significant interaction between site and season on the movement frequency of scallops. In ~50% of the surveys, the net movement direction of scallops was significantly related to the direction of the main current vectors over daily to monthly periods, whereas in the other cases the net movement direction was independent of the direction of the main current vectors. The results of this study indicate that local hydrodynamics is not a good predictor of the swimming dispersion of juvenile P. magellanicus in natural habitats. -from Authors
