Preliminary scheme of large scale swordfish (Xiphias gladius) in the Indian Ocean.
Besides the difficulties in gathering sufficiently reliable fisheries data for stock assessment, the problems of determining stock structure, the spatial distribution, the mixing zones remains the important factors to realize a stock assessment project. In parallel with other techniques like biological, chemical, parasitical tags (otolith, DNA and parasite), the tag could contribute towards providing a better knowledge on the migration pattern of swordfish betwe en the Indian Ocean towards the Atlantic (South Africa) or the Pacific (Australia). Within a particular stock, the knowledge of the individual behavior in a smaller area could help to model the spatial distribution following the size and/or the sex that ca n be indispensable for VPA Analysis.
