Algunas características biológicas de peces capturados en una campaña costera invernal en 1993, en el área comprendida entre 34° y 42° S (Atlántico Sudoccidental) y su relación con las condiciones ambientales.
This paper deals with some biological features of fishes collected during a winter survey from northern Argentine-Uruguayan Common Fishing Zone (CFZ) to the south of El Rincon (Buenos Aires province, Argentina). A total of 167 fishing hauls with a bottom trawl net was carried out in the studied area. The main fishes considered were the following: whitemouth croaker (Micropogonias furnieri), stripped weakfish (Cynoscion striatus), Patagonian smoothhound (Mustelus schmitti), Brazilian flathead (Percophis brasiliensis), Argentine seabass (Acanthistius brasiliensis), flounders (Paralichthys orbignyanus, P. patagonicus) and (Xystreurys rasile), and angel shark (Squatina argentina). A total of 185 temperature and salinity profiles were made but only the latter were considered for the comparison of fishes abundance. The relation between the physical conditions and the distribution pattern of fishes showed that M. furnieri and P. orbignyanus were extreme eurihaline species while M. schmitti, P. patagonicus and S. argentina were eurihaline species with a low range of tolerance. P. brasiliensis, A. brasiliensis and X. rasile showed low tolerance to salinity variations.
