Abstract

The purpose of this investigation is to comprehend how this high-quality fishing instruction is affecting the reef  systems along the coast, reducing the amount of the target species Panulirus echinatus and its related fauna. A region without gillnet fishing was compared to a region with a lot of gillnet fishing in the study. During the night time visual census analysis of the target species, P. echinatus were found in significantly greater numbers at the location where gillnet use was virtually non-existent in all three of the sampled habitats the fringe, the cave, and the soft bottom. 4 lobster species and 10 crab species were found in bycatch species from distinct anglers’ gillnet arrivals. As detritivores, herbivores, and first consumers in the reef ecosystem, these decapod species serve as natural prey for numerous reef fishes. The ecological function of Brazil’s tropical coastal reefs is affected in an indirect way by this.
