Presentation of the project content:
In Hungary, fish are farmed in earthen ponds. Our most important economic fish is the farmed lake trout. Carp of different ages are fed on abstracts to supplement the natural food produced in the ponds, which the fish use as a source of protein. As the natural food base of the ponds decreases in the second half of the breeding season, the feeding of high-protein, complete diets for rearing is becoming increasingly important in domestic carp farming technology. Another advantage of feeding on feed is that larger size food fish can be reared without fattening the flesh. The economics of fish farming are largely determined by the price of feed, with fishmeal being a particularly important component, and its price is constantly rising. Fishmeal can be partly replaced by relatively high protein abrakhulins, mainly soya. The protein content of extracted soya meal is relatively high, but its amino acid and fatty acid composition is inadequate. The high protein content of algae and their high essential amino acid and fatty acid content have led to an increasing interest in the use of algae in animal feed. Inexpensive algae can be used as a partial substitute for fishmeal and soya meal, which can increase the economic viability of carp farming at home. Carp are omnivorous and do not consume algae directly. It is therefore necessary to “incorporate” algae as a feed supplement into the diet.
A total of 125m3 in the Zöldségcentrum Kft. algae is produced in an algae culture system with a useful volume. Currently the algae biomass produced is stored, sold and used together with the nutrient solution. The project aims at expanding the algae biomass use sectors produced. In order to achieve these objectives, it is necessary to improve the processing technology for algal biomass. Algal biomass processing involves a number of steps to convert the algae suspension into an algae powder product. By drying the resulting biomass, we aim to improve the product’s manageability and maintain its stability over the long term without special storage conditions. For use as a feed supplement, in most cases it is expected that dried algae powder will be supplied by the producer, as the vast majority of existing feed producers have production technologies adapted to dry feedstocks. Our aim is to produce algal powders of a quality and quantity that will enable SzegedFish Ltd. to provide the amount and quality of proteins and fatty acids necessary for the development of the fish when mixed with the feed used. Another aim of the project is to make fish farming more economical through the development of feed technology. The use of algae as a feed supplement is also expected to increase the concentration of omega-3 fatty acids in fish meat, which has a very important health-promoting role in human nutrition.
Within the framework of the project, Bay Zoltán Nonprofit Ltd. is developing the algae production and processing processes to laboratory scale and is actively involved in scaling up and optimizing these processes to plant level, as well as in testing samples of fish feed and fish meat.
