A habitat-based simulation framework to design tag-recapture experiments for tunas in the Indian Ocean. Application to the skipjack (Katsuwonus pelamis) population.

The IOTC initiated a discussion to organize a large scale tagging program concerning the major tropical tuna species and fisheries. According to the terms of reference for the working party on tagging (Anon., 1999), prospective simulations are needed to help designing tag -recapture experiments. The purpose of this paper is to present the methodology developed to help designing the future tagging program. It is based on three stages: tag recovery simulations with an habitat -based advection-diffusion-reaction model; bootstrapping of the recovery data sets; population parameter estimation and comparison of scenarii. Different scenarii are studied to check the reliability of the method and its ability to compare various t agging experimental designs. 'Research Group' IRD, HEA911, Ay. Agropolis B.
