An important part of the fishing
activity in Mexico is carried out in the coastal strip and has a strong social,
economic and ecological importance. In the state of Guerrero, mollusks fishing
is coastal and craftwork activity focused on a small number of species and
without information on biology and reproductive or ecological aspects for most
species caught. This research was carried out in the Costa Chica region,
Guerrero, Mexico and the aims were: 1) To analyze the socioeconomic features of cooperative societies of
fishing production; and 2) To know the diversity
of mollusks caught by coastal fishing and the species that have the greatest
importance in fishing. From February to April 2013-2015, seven fish coop units,
four piers and places where seafood is sold were visited. For the
socio-economic analysis and the determination of the species that have more
importance in the coastal fishing, a total of 67 surveys were applied. In order
to determine the cast of species, the specimens captured by the fishermen were
used, which were identified and counted. A total of 67 interviews were analyzed
and an average of $1806.00 was estimated as weekly economic income just as a
product of fishing, it was also estimated that on average the fishermen work
4.3 days a week. Fisheries cooperatives market most of their produce directly
to restaurateurs and locals on the piers. Replacement of older adults by young
fishermen from the same region was observed, most are adults between 22 and 39
years old. 25 species of mollusks of economic importance were registered for
the coastal fishermen of the Costa Chica. Six species were identified as the
main target for catching fishermen. The fishing of mollusks in Costa Chica is not subject to any type of control, which has led to overfishing
reflected in the decline sizes and banks in populations of commercial
importance.
