Distribution and growth in juveniles of the squid Berryteuthis magister (Cephalopoda, Gonatidae) in the western Bering Sea
Seasonal distribution, size composition, age structure and growth of Berryteuthis magister juveniles (mantle length from 20 to 130 mm) were studied in the western Bering Sea (from 1700E to 179°W) between June and October 1994. According to the analysis of 1030 statoliths, the juveniles hatched from...
