Sistema de depuración de moluscos bivalvos con recirculación, a nivel de laboratorio: evaluación y socialización

Abstract

Depuration consists of keeping bivalve mollusks in clean seawater tanks in conditions in which it enables and allows their natural filtration to act and eliminate bacterial contaminants. Bivalve mollusks are exposed to pathogens requiring control measures for production and marketing. The objective of this project is to evaluate the operation of a depuration system with recirculation of water, at the laboratory level, determining the behavior of the physicochemical and biological variables, comparing them, adjusting it to the established standards and socializing the benefits of the system. The project was divided into three sections: first the monitoring of the physicochemical variables using a multiparameter, with measurements during the morning and afternoon for three days for Anadara tuberculosa, Crassostrea gigas and Anadara similis. Second, the calculation of the condition index by measuring the volume and wet weight of the bivalve mollusks, and then subjecting the meat and valves to drying. Finally, the socialization of the benefits, brochures were made with information about the depuration system. It was found that the variables were adequate for depuration, the CI only showed a significant difference in A. similis, the delivery of brochures was well received by the representatives of two shellfish communities. The bivalve mollusk depuration system has the capacity to improve and ensure their quality, contributing to the acceptance and application of new procedures by the fishermen communities of the country.
