Gasterópodos con potencial económico asociados al intermareal rocoso de la región marina prioritaria 32

Abstract

There are numerous species of gastropods of commercial importance; they are used for meat and for their shell, in addition to the potential use of their toxins for pharmaceutical use. There are few studies focused on the analysis of the importance and/or the economic potential of these organisms in the State of Guerrero, Mexico. This research was conducted at 7 sites, with the aim of determine the species of economic potential, the current use and possible commercial use, besides estimating the descriptive statistics of population sizes and geographic distribution. According to the regionalization of the National Commission for the Knowledge and Use of Biodiversity, the sampling sites are located in the Marine Region Priority 32. Species with economic potential were determined as a basis of the abundance of populations and the frequency of occurrence at the sampling sites. Forty species of economic potential were found, of which 14 are commercially exploited, one has biomedical potential and 25 of them no record was found indicating any commercial utilization. The species of greater size was Macrocypraea cervinetta. Sixty five percent of the species with economic potential are of wide distribution. The region is highly diverse and with potential for commercial use of a large number of species. To carry out a good fishery management of the species with economic potential, fishery-biology and ecological studies are required that allow for the development of measures and strategies for carrying out sound and sustainable use of these resources.
