CERROS CORNELIO, J. C. et al. Species composition and income from coastal fishing mollusks on the Costa Grande of Guerrero Mexico. Revista bio ciencias [online]. 2021, vol.8, e1054.  Epub 04-Oct-2021. ISSN 2007-3380.  https://doi.org/10.15741/revbio.08.e1054.

Mollusks are a valuable food source and have a high commercial value. In Guerrero, Mexico, this natural resource is at risk due to inadequate exploitation and the lack of biological and fisheries studies. This research focused on determining which species are caught for commercial purposes and looking for information on the captures of mollusks made by artisanal fisheries. The sampling took place from May to December 2017, and consisted of visiting the Cooperative Fisheries Production Societies (CFPS) as well as places where mollusks are commercialized, where species were identified and quantified in situ. A total of 1,184 organisms were examined, 24 species were identified. The species Striostrea prismatica, Trochita trochiformis and Hexaplex princeps are the ones with the highest volume of catch and are also the ones that generate the highest economic income in the region.
