Aspectos biológico-pesqueros de la merluza de cola del Atlántico Sudoccidental
(Mar del Plata: Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), 1984) Bezzi, S.I.
The distribution areas and population structure of the long-tailed hake are analized. Data come from fisheries research cruises carried out by RV Walther Herwig and Shinkai Maru in the Argentine Sea in 1978/79. Macruronus magellanicus is a typical cold waters species of the Southwest Atlantic and Southeast Pacific Oceans. Maximum concentrations were found in the southern Patagonian shelf, in coastal waters and in depths below 200 m. Spawning individuals were observed on the continental slope in the southern extreme of the Patagonian shelf (54°). The distribution area extend to 93,439 n mi² in spring and to 12,368 n mi² in summer.
