Response of individual shoaling Atlantic cod to ocean currents on the northeast Newfoundland Shelf
The movements of sonically-tagged Atlantic cod swimming within a large (80,000 mt) shoal of post-spawning fish on the northeast Newfoundland Shelf were related to the acoustically determined position of the shoal and event structure in the local ocean currents. For the first several days of the stud...
