| Fishery statistics of austral demersal fishes in the Southwest Atlantic (1980-2002 period). A synthesis of the information available about catches of austral demersal fishes and fishing efforts reported by different fleets that operated in the SW Atlantic between 34° S-58° S in the 1980-2002 period is made. Species included in the analysis were southern blue whiting (Micromesistius australis), patagonian hoki (Macruronus magellanicus), patagonian toothfish (Dissostichus eleginoides), red cod (Salilota australis), southern hake (Merluccius australis) and ling (Genypterus blacodes). Annual and monthly catches, fishing grounds, number of vessels that participated in the fisheries, main landing ports and other characteristic of interest are presented. When it... |

| Southern hake (Merluccius australis) age and growth were estimated using sagittae otoliths obtained in research cruises and observers programs in the Argentine Sea (SW Atlantic). The only annual growth ring observed, formed by two bands, one hyaline and another opaque, corresponded to winter and summer growth, respectively. According to the analysis of otoliths edge, birthday was established on 1st July. Within the age range observed, that comprised 3-18 year old specimens, age groups 7, 8 and 9 were the most frequently identified in both sexes. Growth parameters estimates showed significant differences between them. |
