Collaborative project: FENA - Efficient and market-oriented production of high-value fish feed additives on the basis of yeast and algae - subproject 1

Project


Project code: 2817302610
Contract period: 15.04.2012 - 14.04.2015
Budget: 598,940 Euro
Purpose of research: Experimental development

The goal of the research activities is the efficient and market-oriented production of high-value fish feed additives on the basis of yeast and algae. A sustainable aquaculture for the production of nutritionally enhanced high-value and healthy fish shall be achieved. The dry fish feed products are characterized by an optimized bioactivity.For achieving goals described, yeasts with a high fatty acid content are identified in a screening and produced in a high cell density cultivation. Heterotrophic algae with an optimized content of polyunsaturated fatty acids will be cultivated in suitable bag bioreactors in an efficient way at optimized processes. The specification of the fish feed will be further improved by the addition of phototrophic protein-rich algae. The fish feed is finally produced to lab-scale and will be tested in the late feeding phase of fish in aquaculture. For achieving maximal bioactivity, the processes will be monitored by analyzing phenolic compounds. Due to the cooperation of partners with long-time experience in process optimization of yeast and algae cultivations and food chemists with partners of the fish feed production and fish aquaculture as well as an industrial steering committee, the consideration of economic needs and the commercial realization is assured.
