Dualistic spawning behaviour of the cunner, Tautogolabrus adspersus (Pisces: Labridae), in Bonne Bay, Newfoundland
Group spawning and pair spawning cunners, Tautogolabrus adspersus, were studied at Bonne Bay, Newfoundland. This is the first recorded occurrence of both types of spawning behaviour of this species at a single location. Group spawning occurred within aggregations of 30 to > 150 fish. Cunners...
