A propos du projet: 

This project was designed to improve the IOTC’s understanding of the impacts of on non-IOTC species and ecosystems associated with IOTC fisheries and, by doing so, contribute to more informed management decisions. The results of the project were expected to improve the scientific knowledge that underpins management advice for tuna and tuna-like species in the IOTC area.

Project activities: 
  • A feasibility study on the use of close kin mark recapture methods to estimate the abundances of various shark species was conducted and a detailed report on the most suitable species for its application was shared with the IOTC Scientific Committee.
  • A review of the FAD Watch initiative was conducted, identifying the strengths and weaknesses of the programme.
  • Awareness raising materials for the safe handling and release of mobulid rays were developed and made available, and a detailed report on the interaction between mobulid species and IOTC fisheries was prepared.
  • A technical report outlining the procedure and time frame required for enhancing the management of skipjack tuna was prepared.
  • The 2019 meeting of the Working Party on Tropical Tunas was held and information from the project was shared with the IOTC scientific community.
Résultats et faits marquants: 

The project has contributed to an improved understanding of the impacts of IOTC fisheries on non IOTC-species and associated ecosystems. More and associated ecosystems. More specifically, the project explored the potential for using close kin techniques to estimate the abundance of shark species, reported on ways to reduce the beaching of Fish Aggregating Devices (FADs) and supported the production of materials to improve the safe handling and release of mobulid rays.

The other key project outcome was the provision of support for the improvement of stock assessments in target fisheries. In particular, the Management Strategy Evaluation (MSE) for skipjack tuna was reviewed and recommendations for improved management procedures were developed. Additionally, the project supported the annual meeting of the IOTC Working Party on Tropical Tunas, which allowed assessment findings to be shared.
