dc.description.abstractLength growth parameters were calculated and total length-weight and total length-fork length relationships, which showed no differences between sexes, were fitted for the South Atlantic bream (Seriolella porosa). Length at first maturity was also calculated. The results were as follows: L (mm)= 490.96k years-¹) = 0.154; t0 (years)= -3.915; W(g) = 4*10-6)*TL³.1989; FL(mm) = 0.8917*TL1.0006);L sub 50 (mm)= 290.61. Natural mortality was estimated at 0.274 and limit age at 11 years. Samples were taken during research surveys carried out in 1999 and 2000 in the Argentine Sea (Atlantic SW). Sagittae otoliths of 374 specimen were used for age determination. Total fish length ranged from 226 mm to 550 mm (1-14 years). Commercial landing data of trawl fleets for the period 1990-2000 were analyzed. Catch per unit effort (CPUE) (kg/h) was calculated and standardized using a General Linear Model. All the variables considered in the analysis year, month, fishing rectangle, fleet and horse power were significant. The CPUE showed an increasing tendency through the years.en
