Distribution of juvenile squid in the Scotia Sea in relation to regional oceanography
A total of 211 juvenile and paralarval squid were collected on five research cruises made in the Scotia Sea region during the austral summer (1996-1999). These included specimens of Alluroteuthis antarcticus (Neoteuthidae), Batoteuthis skolops (Batoteuthidae), Brachioteuthis sp. (Brachioteuthidae),...
