| Hake (Merluccius hubbsi) biomass in the Argentine and Uruguayan sectors of the Argentine-Uruguayan Common Fishing Zone (AUCFZ) and in the area that extends from the limit of the shared zone to 41° S was estimated (SW Atlantic Ocean). The contribution to the strata total biomass in each sector was analyzed and complemented with observations on the structure of the population. The basic data to estimate biomass derived from the evaluation surveys of the Hake Project carried out in winter or spring 1994, 1996-2001 and 2003. In 1999 biomass north of 41° S decreased to 30. (112,280 t) of the estimates made for 1994. In 2000 it increased to 165,000 t and in 2003 it was estimated at 156,407 t. A remarkable decrease of the AUCFZ percentage of contribution to the... |
