The distribution, abundance and population structure of Illex argentinus in relation to the oceanographic conditions during summer 1997, were analyzed as a result of the research cruise carried out by R/V Shinko Maru No.3 on the Argentine shelf (39-50°30'S). Besides, abundance and biological features of Ommastrephes bartrami are analyzed. The main activities carried out during the cruise included jigging operations, tagging (only for I. argentinus) and biological sampling. In addition, meteorological and oceanographic data were collected. A total of 30,2000 individuals were tagged and released. The recapture rate was 0.156. (47 recoveries/30,200 released), considerably higher than that of 1996 (0.030; 4 recoveries/13,191 released). I. argentinus was... |
