Efficiency of Using Natural Zeolites in Cultivation of African Catfish

The article represents the results of studies in zeolite use fish feeding. influence zeolites on exterior and interior characteristics African catfish grown high-technological industrial aquaculture was evaluated. Zeolites were introduced into feed amount 3 % 5 %. feeding has had a positive impact growth, indicators fish. In five-month-old catfish, when using zeolites, average daily growth increased by 4.15 g (with addition zeolites) 4.68 zeolites), compared to that did not receive zeolites. experimental groups, there also an increase absolute 124.4 g-with 140.2 commercial weight 24.05 35.52 %, respectively. show growing fish, composition fastens its significantly reduces costs. 1
