9 th International Forum on Tilapia
Position of Tilapia Among Primary Farmed Fish and Aquaculture Technical Difficulties Kevin Fitzsimmons, Ph.D. University of Arizona, Professor of Environmental Science World Aquaculture Society, Past-President Aquaculture without Frontiers, Past-Chairman American Tilapia Association, Sec. Tres. 9 th International Forum on Tilapia HaiKou, HaiNan November 2012
2
Tilapia: continuing to increase in popularity globaly
Tilapias are second only to the carps as a farmed food fish. But tilapia have unique characteristics that will facilitate its continued growth to someday surpass carp production.
3
Tilapia Model for how aquaculture industry should develop
Global demand, variety of production systems and geographic regions, some vertically integrated Environmentally sustainable – “Green Aquaculture” (no fish meal required in the diet, no antibiotics, many farms use effluents for crops)
4
Subsistence and Export Commodity
Tilapia is unique in its role as a small livestock animal grown by subsistence farmers in developing countries around the world….. And It is widely grown and exported to high value markets to be served in expensive restaurants and grocery stores Commodity or specialty crop - BOTH, like chicken

Technical Difficulties
Improved genetics and seed Improved nutrition and feed quality Reducing problems with off-flavor Reducing environmental impacts of aquaculture
11
Improved Genetics and Seed
Farmer need higher quality seed Requires improved breeding programs More high quality hatcheries More all male fish Need to utilize most advanced genetic tools
12
Selective breeding and genetic improvements
Excellent breeding programs - G.I.F.T. - Malaysia - G.I.F.T., Shanghai, and private - China - Genomar - Brazil and Norway - Chitralada – Thailand - TabTim – Thailand (CP Group) - GIFT Excell – Philippines - Molobicus - Philippines - GIFT Bangladesh YY Supermale - Philippines and Swansea, Egypt and Indonesia

Genetic improvements in tilapia
(From: Mair, G., 2002)
14
Tilapia Genome Project
March First assembly of the tilapia genome Oreochromis niloticus – Nile Tilapia Matching many segments to those known from other fish Publically available and freely accessible Next frontier of genetic program for tilapia
16
The YY male technology (GMT®)
17
Improved Nutrition and Feed Quality
Farmers want high quality feeds at lowest cost Feed mills want additional effective ingredients Environmental groups want minimum fish meal and fish oils
18
Farmers want high quality feeds at lowest cost
Farmers should select feed based on quality, cost and service Researchers should work with mills to test new ingredients Vendors should compete to offer new and improved ingredients.
19
Feed mills want additional effective ingredients
New ingredients: Camelina, dried distillers grains, hydrolized feather meal, new soy products Alltech, OlMix, Novus, Uni-President, etc. Improved extruder and pelleting technologies
