Common Carp (Cyprinus carpio L.) Characteristics under Conditions of Culture Based Fisheries in Tudakul Reservoir, Uzbekistan

Ummatova M, Yuldashov M.A., Kamilov B.G.

As a result of reorientation of fish capturing to culture based fisheries in Tudakul reservoir, Uzbekistan (reservoir area 21 000 ha), fish catch increased from 150 - 210 tons/year before 2003 up to 624 1458 tons/year since 2006. Fish productivity increased from 5.3 to 31.4 69.3 kg/ha. Since 2004 reservoir is stocked every autumn by summerlings of common carp (Cyprinus carpio) and chinese carps. Fattening period lasts 2 years. Fish catch is oriented only to large (more than 1.5 kg) fish. Correlation between summerlings biomass stocked and catch of stocked species after 2 years of fattening period was determined (r = 0.77). The largest common carps catches were after 2 fattening years as a result of stocking density on the level 200 summerlings/ha.
