Developing Sustainable Aquaculture for Coastal and Tilapia Systems

Developing Sustainable Aquaculture for Coastal and Tilapia Systems in the Americas Aqua. Fish CRSP Westin Chosun Hotel Busan, Korea May-2008

• Development of snook (Centropomus spp) seed production technology for application in aquaculture and restocking of over fished populations • Incorporation of the native cichlids, Petenia splendida and Cichlasoma urophthalmus into Sustainable aquaculture: Improvement of seedstock and substitution of fish meal in diets • Elimination of MT from aquaculture masculinization systems: use of catalysis with titanium dioxide and bacterial degradation • Rural aquaculture in the northeast of Mexico

Development of snook (Centropomus spp) seed production technology for application in aquaculture and restocking of over fished populations Project Goals • Perform a technological package for the introduction of snook (Centropomus spp. ) to aquaculture in southeast Mexico

Progress Establishment of the study facility – Research area with the maintaining of snook broodstock – Development of the spawning, nursery and phytoplankton production system Future work – Experiments with hormonal induction for spawning

Incorporation of the native cichlids, Petenia splendida and Cichlasoma urophthalmus into Sustainable aquaculture: Improvement of seedstock and substitution of fish meal in diets Project Goals Develop of researches in selection seed improve and substitution of fish meal in feed

Progress • Establishment of the seed selection system at UJAT • Selection of broodstock Future work – Improvement of seed selection

Elimination of MT from aquaculture masculinization systems: use of catalysis with titanium dioxide and bacterial degradation • Develop of masculinization systems • Collection of bacteria samples for bioreactor

Conferences co-funded by Aqua. Fish CRSP Algae conference • Schedule slipped due to delays in funding. • New plan is to hold a special session at WAS 2009 in Veracruz. Special session has already been approved by program committee. ISTA 8 • Symposium is coming along very well. Oct 12 -14, 2008 at Cairo Convention Center. • Website and other organizational aspects have all made excellent progress. • Many registrations and abstracts are already in hand. • Lots of co-sponsors have signed on, providing extra funds.
