Patterns in Coastal Migration and Stock Structure of Capelin ( Mallotus villosus )
Approximately 57 500 mature capelin (Mallotus villosus) were tagged with external tags from 1983 to 1988 along the southeast and east coasts of Newfoundland to determine inshore migration patterns and to reexamine the current belief that two separate capelin stocks spawn on east coast beaches. Capel...
