Influence of free choice of feed on the productive qualities of two-year-old carp (cyprinus carpio l.) in ponds

The results of research on the effect feed with different feeding values and organoleptic properties productivity two-year-old carp are presented. Within same pond, joint use demand feeders (feeds tastes) makes it possible for fish to choose one them in response well-developed chemoreception. Diets calories affect quality resulting production at consumption. combination two types within pond provides food savings per gain, despite higher total Two-year-old give preference more high-energy food. At time, consume 1/3–1/4 low-energy food, regardless time. mass consuming only is 1.7 2.6 times less than that simultaneously these foods, respectively. Combined contributes an increase relative muscle mass, primarily comparison fed a diet. Fish-farming biological characteristics indicate yielding qualities case simultaneous (K-111 Karp-38/12). Taste priorities must be considered aquaculture farming.
