Predatory fish is valuable fish material, necessary for planting of pond fisheries along with natural water reservoirs. The most popular predatory fish are: pike (Esocidae), pike-perch (Lucioperca lucioperca L.), silurus (Silurus glanis). Current technology, used for predatory fish reproduction, is not effective. Artificial growth of fish larvae in incubation section and future run-out of small species in industrial ponds leads to almost total death of fish because of low (0.1%) vitality level. The results of the research, based on new approach to fish larvae growth, are presented in the article. Research of vitality of larvae, fingerlings and young fish of Esocidae and Siluridae, grown with the use of special feeding, is shown. Growing of larvae, fingerlings and young fish in artificial conditions using special technologies, increases vitality level of larvae and decline losses of young fish. The increasing of resilience of young pike and European catfish, due to the introduction in the diet of larvae of starter feed of domestic production is determined. The effect of mixed feeding on blood parameters of fish, the ability to respond to the extreme effects of the environment and on the biochemical composition of the body of studied fish is revealed.
