The biomass of the coastal lagoons of the Miskito Cays Reserve

Abstract

The study of the fish biomass of the coastal lagoons was carried out in the coastal lagoons of Bihmuna, Pahara, Wounhta and Karatá. Its purpose was to determine the present biomass of the fishing resources existing in the four lagoons studied during the summer and winter seasons and to address the current problems that exist in these lagoons for fisheries regulation.This quantitative approach study used four sampling units (atarraya, gillnets, purse seine net and ring) and random sampling points were selected in the lagoons; which were for a period of 24 hours (day and night), where different fishing tools were used. In relation to the results, the biomass of the lagoons was higher in winter; however in the summer there was a greater presence of individuals in juvenile and pre-juvenile states In the summer sampling, there were catches of penaeids in the lagoon of Bihmuna and Karatá where the individuals captured for the most part were of a state of pre-juvenile maturity. It is important to mention that the Bihmuna lagoon in the winter time there was the presence of penaeids; this is due to the circulation of dissolved salts in the water that is the product of the entry of water from the ocean that enters this lagoon through the two mouths it has
