This study analyzes the degree of effectiveness of artificial reefs as a means of increasing the population of the ichthyofauna in a community in the Gulf of Fonseca, whose currents of turbidity, sediments, atmospheric components, and organic matter in rocky areas are highly productive, providing food and shelter for a diversity of fish, oysters, crabs, and other organisms. The fishing community of San José de la Conchas in the municipality of Marcovia was selected, where prior to the launch of the domes, a first capture was made in the winter season and another two months after the structures were released in the summer. In addition, the sediments present at the deposit site, the levels of sediment contamination and other parameters were analyzed. In this first phase of the study, nine species were identified, of which eight are commercial, it was determined that the largest volume of biomass was generated in winter, declining in summer as a result of the change in currents and that the mimicry of artificial reefs determines the success in the generation of reproductive microsystems in the food chain that contributes to the food security of the fishing population of the area.

Keywords : Gulf of Fonseca; ichthyofauna; artificial reefs; increase; diversity index.
