Overall, the Aquaculture CRSP demonstrated strong involvement in tilapia research and commitment for tilapia aquaculture development in the region.

total tilapia production in China in 2002. Amrit Bart, Coordinator of AARM at AIT, presented on AARM contributions to tilapia research. In his presentation he acknowledged the strong cooperation between the Aquaculture CRSP and AIT in conducting joint research on tilapia, which resulted in several valued publications in peer reviewed journals. He noted that joint research conducted by Aquaculture CRSP and AIT to optimize tilapia production by improving primary production and husbandry practice during 1980s became a theme that continues today at AARM, AIT. C. Kwei Lin presented two papers related to red tilapia culture in brackishwater. He observed that red tilapia grew better in brackishwater than in the freshwater, and the best growth performance was achieved at 10 ppt salinity. He also found that under fertilization system 50% satiation feeding was the most efficient feeding rate to grow red tilapia. M. K. Shrestha presented two papers, one on control of Nile tilapia recruitment by predatory snakehead and second on grass carp Nile tilapia polyculture. His research findings showed that snakehead were able to control Nile tilapia recruitment completely and thus, may provide an alternative technique for Nile tilapia culture. D. P. Thakur presented research on fertilization and feeding strategy for Nile tilapia grow-out ponds, and concluded that combination of fertilization and feeding should be a preferred strategy over fertilization followed by feeding for culturing Nile tilapia.
Yang Yi was the leading presenter in the group with four oral and four poster presentation in ISTA6. Details for all the presentations made by the group can be found in the ISTA6 proceeding as manuscript for all the presentations was published in the Symposium proceeding; ISTA6 published two volumes of proceedings edited by Remedios Bolivar of Central Luzon State University, Kevin Fitzsimmons of the University of Arizona, and Graham Mair of Finders University. The list of all the presentations made
Presentations:
• Amrit Bart, Contribution of Aquaculture and Aquatic Resources Management (AARM) Program of the Asian Institute of Technology (AIT) to Tilapia Research.
• Yang Yi, Stocking densities of Nile tilapia in shrimp ponds under different feeding strategies.
• C. Kwei Lin, Effects of fertilization rates on growth performance of red tilapia at different salinities.
• C. Kwei Lin, Supplemental feeding for red tilapia culture in brackishwater.
• Yang Yi, Stocking densities and fertilization regimes for Nile tilapia (Oreochromis niloticus) production in ponds with supplemental feeding.
• Yang Yi, Stocking ratios of hybrid catfish (Clarias macrocephalus x C. gariepinus) and
IIFET 2006 Conference
The Aquaculture CRSP is proud to announce that it will be co-sponsoring the next upcoming International Institute of Fisheries Economics and Trade (IIFET) biennial conference, IIFET 2006 Portsmouth.
Current theme ideas include: Fish for the future: recovering fisheries from collapse; and Biodiversity: fisheries and the ecosystem (including modeling fisheries' interactions with the environment). The organizers welcome ideas to strengthen the seafood markets portion of the program, a post-tsunami assessment session(s), and other topics.
IIFET will post news about the upcoming conference, including a first call for abstracts by late July 2005 and a detailed second call/announcement by early December 2005.
For questions or topic ideas, contact:
Nicola Waterman, Conference Coordinator
