Última Dinámica de la metapoblación de almeja panopea Panopea abbreviata en los golfos norpatagónicos OceanDocs Zaidman, P.C.. Panopea abbreviata es el molusco bivalvo infaunal de mayor tamaño del Mar Argentino. Se distribuye desde Río de Janeiro (Brasil) hasta la Patagonia Argentina. En los golfos San Matías (GSM) y San José (GSJ), conforma una metapoblación que presenta una distribución discontinua, formada por una serie de poblaciones ubicadas a lo largo de las costas.Es el bivalvo más longevo explotado en el Atlántico Sur. En el GSM su pesquería comenzó en el año 2000 y, si bien la misma es incipiente, debido a las características biológico-poblacionales de P. abbreviata es un recurso que requiere de un manejo precautorio. Excepto por estudios preliminares sobre el crecimiento y el ciclo reproductivo, no se contaba con la información básica para manejo. El objetivo general del...

Coastal marine ecosystems are highly variable and the inherent biotic and abiotic factors of these environments can influence the bio-ecological characteristics of the living cephalopods. The presence of the small octopus “pulpito” Octopus tehuelchus in the coastal environments of San Matías Gulf has been exploited by artisanal fishermen for more than 60 years. The aim of this study is to evaluate the variations in the life cycle of the pulpito, and the factors that could account for these variations in three different coastal environments of San Matías Gulf, with differences in the physical, ecological and fisheries characteristics. This study was developed in San Antonio bay, El Fuerte and Islote Lobos. Monthly samplings (October 2005-2007) in the...
