Length and age at first maturity was estimated, and the distribution of the spawning stock of castaneta (Cheilodactylus bergi) was analyzed, with the aim of understanding the spawning activity and its relation with oceanographic parameters. Samples came from two research cruises carried out in the Argentine-Uruguayan Common Fishing Zone (CFZ) (SW Atlantic, between 34 degree and 39 degree 30'S), during the end of spawning period (May-June) of 1991 and 1993. Length at first maturity was estimated in 21.34 cm and 23.69 cm of total length, for males and females respectively. Age at first maturity estimated for sexes combinated corresponding to 2.60 years. A spawning area in the north (between 35 degree and 37 degree S) was determined, showing a high incidence... |

The aim of this study was to determine the chemical composition and fatty acids profile present in Argentine anchovy (Engraulis anchoita) northern population as a function of fish size and fishing area (SW Atlantic Ocean, Argentine Sea). Samples were collected during the northern stock assessment cruise of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) carried out on board of FRV Capitán Oca Balda in Spring 2008 (OB-02/2008). The fishing trawls were performed between 34º 35' S and 40º 19' S. The area was divided in two zones: the northern, between 34º S-38º S, strongly influenced by the mixohaline waters of the Río de la Plata River estuary and the southern, between 38º S-41º S, that included the El Rincón coastal area. In each... |
