| Abstract |
The mollusks caught by coastal fishing were analyzed as a resource, as well as the socioeconomic condition of the fishermen involved in this activity, who are members of the fishing cooperatives of the Costa Grande of the state of Guerrero. The objectives were to be acquainted with the list of species fished for human consumption, determine those of greatest economic importance, analyze the socioeconomic characteristics of the fishermen, and determine the current state of the mollusk resource based on the fishermen’s perception. The specimens were acquired from landing zones and restaurants, and a total of 27 surveys were conducted with fishermen, members of fishing cooperatives in the region. A total of 24 species of mollusks were identified; 10 were the target species for fishing, and seven species were not economically profitable for fishermen. Striostrea prismatica, Trochita trochiformis, and Hexaplex princeps generate more income annually. Five species have been excluded from the list of catches: Megapitaria squalida, Periglypta multicostata, Pinctada mazatlanica, Malea ringens, and the giant limpet Scutellastra mexicana. There was no evidence of generational replacement in the fishing activity. The fishermen’s income is sufficient to cover their basic needs and those of their families. The current regulations are insufficient. There is an urgent need to carry out technical-scientific and biological research to provide relevant information that can be used to implement measures for the appropriate use and regulation of mollusk fisheries in the regio |
