| This report contains the objectives, data collected and results from a hake assessment survey carried out in the Argentine Sea between 34° and 46° S, during July and August 1994, on board of the R/Vs "Dr. E. L. Holmberg" and "Cap. Oca Balda". The main objectives of the survey were: 1) to estimate total biomass and total abundance per age class; 2) to study the size and age composition; 3) to define the maturity ogive per size and age; 4) to quantitatively determine cannibalism and predation indexes. The area covered by the survey where 149 trawls and 184 oceanographic stations were performed was close to 100,440 nm2 . Hake biomass between 34° and 46° S was estimated in 1,105,284 tons and the confidence interval at 95. was ± 23.12. . Most of the biomass... |
