Implicações etnoconservacionistas quanto ao manejo informal do marisco Anomalocardia flexuosa (LINNAEUS, 1767) por marisqueiras

Abstract

The mollusk gathering activity can be understood as the artisanal fishing of molluscs, where their management can be carried out manually or with the aid of fishing gear being the main one for the Northeast region the exploitation and commercialization of shellfish (Anomalocardia flexuosa). The objective of this work was to analyze the practice of the informal management of shellfish, manually collected by mollusk gathering in the northeast coast of Brazil. The study site was the Acaú-Goiana Extractive Reserve, located between the states of Pernambuco and Paraíba. The research was carried out during the years 2017 and 2018, consisting of immersions and random visits in the communities of Acaú and Carne de Vaca, based on participant observation. From the separation in the small and large sizes, adopted by the mollusk gathering, measurements were made for the height, length and width of the shells. A total of 11 shellfish were culled and separated from the mollusk gathering, totaling 1793 shellfish, totalizing of 1,793 selfish, 685 small (discarded) and 1108 gross. The size of intersection between picking or discarding shellfish occurs with sizes from 18 to 20mm for the overall length, which is biologically sustainable. This action results in a reduction of the overfishing process, since the seafood caught is already sexually adult, that is, they have already passed through the process of reproduction, and the despised can
