Population structure, growth, and sexual maturation of short-finned squid (Illex illecebrosus) at Newfoundland
We describe size at age, growth, and population structure of short-finned squid (Illex illecebrosus) from Newfoundland waters during 1990. Ages were estimated from statolith increment counts and used to back-calculate hatching dates. Hatching ranged between December and June with the hatching months...
