The main objective of this diploma thesis is compare the production efficiency of special types of feed for African catfish in experimental conditions in a recirculating system with biological treatment of water. It was tested four different types of floating feed, differing in the proportion of main components, the chemical composition and determining - for catfish (CatCo GROWER - 12 EF, CatCo SELECT - 13 EF and CatCo GROWER - 13 EF), respectively salmonid fish species (Dibaq Trout Evolution). The primary outcome indicators was the growth rate, individual weight (and it's variability), feed conversion ratio, the cost of feed consumed per unit of growth and product quality, evaluated according the average dress-out percentage of skinless fillets, organoleptic assessment and chemical composition of flesh.
