Manejo de parámetros físicos y químicos para la reproducción de la concha prieta <b><i>anadara tuberculosa</i></b>

Abstract

The harvesting of Brown Shell, scientifically known as Anadara tuberculosa, has been a livelihood for years in the communities around the mangrove shores. However, due to overexploitation by shellfish harvesters and at the request of food eaters, these mangrove areas are running out of organisms to harvest, leaving increasingly lower densities to be harvested, thus altering the conch communities by reducing their population. The mangrove areas have been affected by anthropogenic pollution, which has an impact on the growth of the conch, the optimal conditions for their development such as temperature, salinity, pH and dissolved oxygen have been altered by this pollution, thus producing uneven growth of the same and delaying their harvesting time, which is why the communities have opted for the cultivation of these organisms in cages in order to have adequate control during their development up to a commercial size. Avoiding an overexploitation of this resource provided by the sea and at the same time obtaining a culture free of any pollutant such as heavy metals, as these species are filter feeders due to their feeding biology. The present work is based on information extracted from bibliographic sources and indicates the management of the physical and chemical parameters for the reproduction of Brown Shell Anadara tuberculosa, in order to obtain a better knowledge and management of the biological and physiological needs of this resource.
