Cost effective technology of marketable fish in pond aquaculture

Abstract

Studies on reclamation ponds of Pripyat Polesie showed their suitability to conduct feeding, cage and integrated fish farming. Results of the studies indicate the appropriateness to use as seeding pike yearlings, two-year carp, grass carp and bighead carp for aquaculture feeding. Growing of sturgeon in cages, using as feed supplements Chlorella suspension, showed that the addition to the feed mixture of 10 % suspension of chlorella on the mass of the food provided to increase the average weight of Sterlet and Lena sturgeon by 19,9 and 25,1 % respectively. This technology saves up 4.3 € (7,5 %) of the 57 € spent on feeding the fish per day. The positive results showed during production of marketable fish in conjunction with the Muscovy ducks. The live weight of ducks that received during the initial period of growing the suspension of chlorella was 9,2 % higher than in the control group.
