| Resumo: | The lack of knowledge of taxonomy and population structure of species that are the target
of fishing conflicts are gaps that must be filled in order to correctly manage fish stocks.
Knowing the origin of conflicts in Marine Protected Areas (MPAs) is also important for
an effective resolution. With this in mind, this work has two main objectives. One is to
investigate the population structure of a conflict target species, the sardine Harengula sp.
on the islands (MPAs) and coast of Brazil, and through a systematic review, about the
variables involved in the origin of fishing conflicts in MPAs around the world, to find
pertinent solutions for such conflicts. In the first chapter, searches were made with
keywords involving MPAs, fishing conflicts and marine parks in the Scopus platform,
totaling 269 documents analyzed. In the first screening made by reading the abstracts,
114 articles were selected for full reading, resulting in 58 that entered the analysis
considering the research objectives. The main criterion for the selection of articles was
the presence of some type of conflict involving fishing in MPAs. It was found that the
main cause of conflict is illegal fishing, followed by fishermen's feelings of exclusion in
the MPA management and creation process, and conflict between fishermen and
conservationists. Artisanal fishing, as well as artisanal boats and fishing gear, were the
most cited themes in the conflicts indicating that traditional fishermen are more involved
in fishing conflicts. The most conflictive type of management was the governmental one
in MPAs of sustainable use. In the second chapter, sequences of the mitochondrial DNA
control region of 152 sardines of the genus Harengula 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) were analyzed. Lineage delimitation, gene flow and molecular variance analyses
indicated three populations: One in FNO, where conflict between fishermen and
environmental management is most exacerbated, with a distinct and diverse stock to be
managed separately; another on the northeast coast (including ABR); and another in southeastern and southern Brazil. This work provides a broad view of the origins of
fishing conflicts in marine protected areas around the world and contributes to the
understanding of genetic aspects of a target species of a fishing conflict in a protected
area in Brazil, bringing together two types of knowledge, biological and social, for better
management strategies. |
