Abstract

Pelagic sharks representing only about 6% of the world's total Chondrichthyes and are among the largest and most wide-ranging predators in the ocean. These species play a critical role in keeping the oceans healthy and in balance. However, pelagic sharks have been caught severely by the longline fisheries worldwide. In particular, this project will focus one of the most important species in terms of catches and economic value, the shortfin mako (Isurus oxyrinchus), which is the second highest proportion of shark species in the international fin trade and are also highly prized game fish. Thus, improving the conservation of shark populations is a focal issue in international fisheries as a result of strong concerns regarding the major decline of these caused by directed fishing and bycatch. In this project will be addressed gaps in life history information for highly migratory and overfished shortfin mako. Specifically, will be used high tech genetic research such as transcriptome characterization and Single Nucleotide Polymorphism (SNPs) to provide a better understanding of the molecular-level functions, as for example physiological process related to local adaptation and test for stock assignment analysis, and advance knowledge of connectivity among populations taking into the account oceanographic features. This Project will therefore provide imperative missing information for the Atlantic populations of this important shark species, which will be disseminated to both scientists and fishery managers. By the end of this Project, will be expected to have significantly contributed to a more responsible and sustainable exploitation of this vulnerable and important marine resource in the pelagic ecosystem.
