| Popis: | The article focuses on the data from foreign literature on growing rainbow trout or mykiss (Oncorhynchus mykiss) with the inclusion of dried and / or fat-free insect biomass in diets. The following seven types of insects could be recommended for inclusion in the diet of rainbow trout and other fish species: larvae and / or pupae of diptera fly (Hermetia illucens), housefly (Musca domestica), flour worm larva (Tenebrio molitor), locusts and grasshoppers (Acrididae), crickets (Gryllidae) and cathidids (Tettigoniidae), silkworm pupae (Bombyx mori). The brief data on physiology and life cycle of these insects are given, as well as the data on proteins and fatty acids concentration in fresh and dry larvae of insects. It has been shown that the flour from dried insect biomass contains a large amount of amino acids and fatty acids. There has been given the data on the influence of flour from insect larvae on the mass increase of rainbow trout juveniles and adults, digestibility of feed dry matter, organoleptic characteristics of fish fillets, amino acid and fatty acid composition, and other indicators. It has been found out that in most cases the survival rate is significantly higher in the experimental groups of Oncorhynchus mykiss juveniles fed a diet containing insect flour. It has been inferred that including flour from insect biomass in certain proportions has a positive effect on the growth and life of Oncorhynchus mykiss species. The most promising is adding Hermetia illucens larvae flour in the diet of rainbow trout in aquaculture, because Hermetia illucens larvae have the highest biomass yield per unit time compared to other insects. |
