Abstract
Los moluscos (bivalvos y gasterópodos), son uno de los recursos marinos más importantes en la dieta de los seres humanos por su bajo contenido de grasas y alto contenido de proteínas de fácil digestión. En este trabajo se estudio la distribución de los moluscos empleados como alimentó en varias playas de isla Colón. Los ambientes marinos explorados fueron las praderas de Thalassia, manglares, rocas, sustrato duro, fango, fango-arena, arena, arena-fango y las aguas (poco profundas y salobres). Los especímenes de playa Istmito fueron los más abundantes (283 individuos), mientras que las muestras de playa Paunch y Boca del Drago fueron las más diversas, con 10 especies respectivamente. El 75.5% de los individuos de bivalvos se localizó en la arena, 11.4% en fango y 8.9% en sustrato duro. Se encontraron diez especies empleadas para alimentación. Un 84.1% de individuos de gasterópodos se encontró en sustrato duro; 7.2% en praderas de Thalassia y 6.5% en roca. Nueve de las especies recolectadas son empleadas para alimentación. La almejita de arena, Donax denticulatus Linnaeus 1758, fue la especie más registrada, con 270 individuos; de los cuales el 79.26% se localizo en la arena de playa Istmito. El estudio revela la importancia de la conservación de las áreas de asentamientos de moluscos que sirven para alimentación de los habitantes del sector y como fuente de ingreso a los pescadores artesanales.
Mollusks (bivalves and gastropods) are one of the most important marine resources in the diet of human beings due to their low fat content and high content of digestible protein. In this paper the distribution of mollusks used as food in several beaches of Colon Island was studied. The marine environments collected were Thalassia grasslands, mangroves, rocks, hard substrate, mud, muddy-sand, sand, mud and sandy-water (shallow and brackish).Specimens from Istmito beach,were the most abundant (283 samples), while the most diversity was obtained from Paunch beach and Boca del Drago, with 10 species from each respectively. 75.5% of Pelecypods were found on the sand, 11.4% on mire and 8.9% on the hard substrate. There was ten species used for food. A 84.1% of individuals of gastropods found on hard substrate, 7.2% in Thalassia and 6.5% in rock. Nine of the species collected are used for food. The little sand clam, Donax denticulatus Linnaeus 1758, was the most numerous species, with 270 individual, of which 79.26% were found in Istmito beach. The study highlights the importance of conservation of mollusk settlement areas that serve to feed the inhabitants of the sector and source of income for artisanal fishermen
