O uso de parasitos para a discriminação de estoques do Pargo rosa, Pagrus pagrus (Perciformes: Sparidae) no Atlântico da América do Sul

Abstract

The global state of marine fisheries and its effects put the future of fisheries at risk, leading to the extinction of species and changes to the ecosystem regime threatening their overall integrity. Fish consumption has increased, thereby warming the market and fishing activities at sea, with a high incidence of endangered or exploited species. In order for an action to be managed efficiently and policies can be implemented for future sustainability, the stock needs to be correctly identified. This study emphasizes the value of different guilds of Pagrus pagrus parasites as indicators of zoogeographic regions in the identification of fish stocks, and evidence the scarcity of studies in Brazil with only one work of corvina, Micropogonias furnieri in the Brazilian coast with the use of parasite as a biological marker. Considering the heterogeneity of the Brazilian coast, Brazil presents a great potential for the use of the technique, as a tool for the greater knowledge of our fishing resources, generating policies of management and conservation of exploited and threatened species, more efficient
