Collaborative project: Efficient and market-oriented production of high-value fish feed additives on the basis of yeast and algae - subproject 1
Project
Project code: 2817301510
Contract period: 01.05.2012
- 30.04.2015
Budget: 178,587 Euro
Purpose of research: Experimental development
Worldwide around 17 % of animal protein for human consumption are from fish (FAO 2006). For 2.9 billion people, fish is the most important source for animal protein. A rise of the fish supply in populous countries of Asia and Africa, like India, China or Egypt, through an increase of production in semi-intensive aquaculture of Carp and Tilapia is possible. Aim of the project is to develop the needed low-cost-feed for carp and tilapia from protein rich by-products of the biofuel production.In arid and semi-arid regions Jatropha curcas L. is one of the most important plants for biofuel production. The press cake has a very high protein content (>60 %). Due to the high level of anti-nutritive substances (especially phorbol esters), the use of jatropha meel as animal feed was not possible to date. However a process for detoxification is available now. First tests using the detoxified material as food for fish and shrimp had promising results. On the base of this material, enriched with lysine, a supplemental feed for tilapia and carp for regional markets in tropical countries shall be developed. Finally, the feed will be tested in outdoor ponds close to practical fish farm conditions in Egypt.
