Se realiza una sinopsis del estado de situación de los recursos pesqueros del Golfo San Matías, de sus pesquerías y especies asociadas a las mismas y del ecosistema marino. El objetivo de este informe es presentar información histórica y actualizada sobre los recursos pesqueros y las pesquerías marinas de Río Negro, a los fines de su empleo como guía de análisis para la evaluación de las mismas con vistas a la potencial certificación de una gestión sustentable de las mismas a partir de los estándares del Marine Stewardship Council (MSC). Se presenta información sobre la organización y estructura del sector institucional y del marco legal en el que se desarrolla la actividad. Se desarrolla una caracterización de las pesquerías a partir de diferentes... |

In this study we analyze growth, mortality and estimated biomass trend of purple clam, Amiantis purpurata, population placed in Playa Villarino, (Northern San Matias gulf, Argentina) in the southern most boundary of its geographical distribution. Previously, the population structure was described composed by three consecutive cohorts settled among 1978-1980, and the individual growth rate showed high spatial variability. The hypothesis to test in this study is that growth rate is regulated by local biomass. We choice four sites with different densities, to assess growth rate, natural mortality and retrospective estimated biomass trend. During February 2003, densities and growth rate (using external growth bands measurements) were analyzed matching with a... |
