Does blue whitting migrate from Porcupine bank to Bay of Biscay after spawning season?
Duiing March-April 1994 and 1996 two cruises have been carrieed out around Bay of Biscay in order to check movements of blue whiting using acoustic methods. These cruises consisted in a double coverage of an area from 47°30' N, 7°15' W to 43º30' N, 6º30'W along the French and spa...
