Requins

Projet: Renforcement de l'Expertise sur la Conservation des Requins

Coordinateur: Serge Planes

Période: 2014-

Zone d'Étude: French Polynesia

Résumé: Active fisheries targeting sharks for their fins have devastated populations globally, particularly on many island nations like French Polynesia, where shark populations have historically been relatively low.

In 2006, shark fisheries were banned across French Polynesia. In support of this effort and to assist with the recovery of shark populations, the ‘Requin’ Project is conducting important research to assess the vulnerability of sharks across Polynesia. Shark populations are notoriously data poor, and to date, researchers know very little about their social organization and rates of reproduction and renewal.

Investigators are using genetics to estimate the genetic structure of Moorea’s lemon shark (Negaprion acutidens ) population. Characterization of the genetic relationships between individuals allows us to determine how a population contributes to its own renewal and in turn provides an estimate of its vulnerability.

To date, this research has yielded some important results which have already helped to inform management decisions. This work - which is now part of a larger Pacific-wide partnership - has also catalyzed shark research elsewhere throughout islands in the Pacific, further contributing to the protection of these important species.
