The University of Arizona and Central Luzon State University have collaborated for many years to develop low cost feeds, tilapia-shrimp polyculture and to co-host the Sixth International Symposium on Tilapia Aquculture in the Philippines. The technologies developed will benefit tilapia farmers around the world as the investigators and students involved with the project work with Arizona and Filipino farmers and test diets at commercial producers.  The first phase of the project was to purchase a pellet mill to improve the quality of test feeds made at the Freshwater Aquaculture Center at CLSU, the premier aquaculture research facility in the Philippines. The second part of the study is to test diets incorporating various substitutes for fish meal in hopes of finding cost effective diets.
