The SEAFDEC active in stock enhancement attended the Aquaculture Department (AQD) based in meeting (Appendix I). A total of 18 country Iloilo, Philippines is tasked to implement and review papers provided status reports and the aquaculture-based component of this scientific input for lively discussions during Program focused on stock enhancement, the concluding workshop.
