Caracterización de los sistemas para la cría y engorde de la concha prieta <i>anadara tuberculosa</i>

Abstract

The Anadara tuberculosa mollusk is a bivalve typical of mangrove ecosystems, becoming an economic resource for communes settled on the banks of this ecosystem as well as being a source of animal protein for them. Extraction volumes depend largely on the demand and economic needs of the communes. The Concha prieta has a wide distribution along the Pacific coast, ranging from Baja California Sur, Mexico, to Tumbes, Peru. This species is found in the so-called substrates. Both in Ecuador and Peru, different means have been sought for the cultivation of this mollusk, the first results were nothing flattering, taking into account the slow growth and low price; however, the types of mechanisms that have been used for the fattening of the prieta shell have an important effect, such as the case of incidental natural repopulation, with the help of the shells, their activity has a great influence by having to make an effort and awareness in a sustainable fishing management where they have alternatives to carry out a rational exploitation and to recover the resources at the same time, the research to be carried out in later years in terms of reproduction is concerned, seed production, fattening systems, nutrition, processing, aggregation to product value, among others. In each of these areas, there are already targeted research projects and some are already being implemented.
