Description
Summary:The article presents data on alternative feed sources composition for thermophilic freshwater crustaceans and cyprinids. We found that the implementation of an agriculture component in the feed is quite capable of replacing the regular parts. Studies have shown that the addition of new elements allows modifying the previously used feed with a positive effect on the potential growth rate of cultivated thermophilic objects. The presented food additives from local, raw materials not only correspond to the food preferences of the cultivated objects but also reduce the cost of feed, thereby increasing its competitiveness in the aquaculture feed market. Based on the detailed study of nutritional characteristics of alternative sources of feed raw materials, effective doses of the compounds have been developed. A partial replacement of scarce fish meal was made with the useful addition of local raw materials- an alternative component of the source of protein from pond ecosystems - 50%, which provides a high growth rate of cultivated objects. A consistent rejection of antibiotics dictated the conditions for the study of the addition of the probiotics of into feed (0.3% -0.5 %) that increase the body's resistance under farm conditions and 100% survival during cultivation. The proposed alternative is the taste addition of a local halophyte plant - 0.1% increase feeding attractiveness, active and united response to the recommended feed, which reduce its conversion. Replacement with alternative sources of feed was made under the basic requirements of organic production of aquaculture products.
