SUMMARY:

Lack of knowledge about taxonomy and population structure of conflict-targeted fish species hinders the correct management of its stocks. The origin of such conflicts in Marine Protected Areas (MPA) are worth investigating in order to propose effective resolutions. With this in mind, this work makes a systematic review of the variables involved in the origin of fishing conflicts in MPAs around the world and investigates the population structure of a species target of conflict in a Brazilian MPA, the scaled-sardine Harengula sp.. In the first chapter, searches were carried out with specific keywords in the Scopus platform, totaling 269 documents analyzed. In the first screening performed by reading the abstracts, 114 articles were selected for full reading, from which 58 were included in the analysis. The main criteria for the selection of articles was the presence of some type of fishing conflict within an MPA. It was found that the main cause of conflict is illegal fishing, followed by a feeling of exclusion from the MPA management and creation process and conflict between fishermen and conservationists. Artisanal fishing, as well as artisanal vessels and artisanal gear, were the most mentioned in the conflicts, indicating that traditional fishermen are the most involved in fishing conflicts. The most conflicting type of management was the governance in sustainable use MPAs. In the second chapter, we used sequences of the mitochondrial DNA control region of 117 individuals from the states of Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Bahia, Espirito Santo, Rio de Janeiro, São Paulo, Santa Catarina, and the islands of Fernando de Noronha (FNO) and Abrolhos (ABR). The lineage delimitation, gene flow and molecular variance analyzes indicated three populations of scaled-sardine along the Brazilian coast: FNO, north, and south clusters. The population in FNO, where the fisheries conflict is stronger, is stock that is diverse and distinct from the one on the northeast coast (including ABR), and the one in the southeast and south of Brazil. These results indicate that temperature and depth act as barriers to gene flow. This work provides a broad view of the origins of fisheries conflicts in marine protected areas around the world and contributes to the understanding of genetic aspects of a target species of a fisheries conflict in a protected area in Brazil.
