1. Tropical Tunas Working Group Recife, April 2007

2. Main topics studied
Update of basic statistics, CAS and tagging database
Estimation of landings that are directed out of the canning factories (“faux-poisson”)
Review of new biological information and fishery indicators for YFT, BET and SKJ
Indicators relevant to multi-species fisheries and ecosystems
Recommendations

3. Statistics
Task 1 and 2: revisions following the work done in Sète (2006)
Sizes: update and building of the CAS for YFT and SKJ
Tagging: progress on improving the tropical tunas databases; still work to be done for YFT and SKJ by Secretariat and scientists
Preparation of BET assessment: revision of the “fisheries” definition and data preparation for Multifan-CL analysis

4. « Faux-poisson » 1- Total amount landed in Abidjan

5. « Faux poisson » 2- Quantities according to the fleet

6. « Faux poisson » 3- Species composition
sampling
sampling

7. « Faux poisson » 4- Size composition
Major Tunas
Minor Tunas

8. « Faux poisson » 5- Conclusion
These landings are quite important and should be taken in account for assessments
Ways to avoid risks of double counting of catches (transshipments, observers) have to be axamined
Studies to better estimate the species composition by fleet should be continued
The way to take them in account in the statistics has still to be defined (discards, new category?)
