Distribution of major carp fishes in minor reservoirs: a case study of nagulakunta water tank, vinjapally of siddipet dist. telangana state

The present study based on the data for 5 years deals with the role of a minor reservoir in fish production and the influence of stocking densities on fish production. Nagulakunta, a minor reservoir with 10 ha of water spread is located in Vinjapally village of Siddipet District. The minor reservoir is treated as stocking and capture system for development of the fisheries. The overall major carp production is 465.88kg/ha/yr, and that of the rest being 56.25kg/ha/yr. The total fish production is 513.13kg/ha/yr. The major carp production increased significantly from 13.43 to 98.02%, and that of others decreased drastically from 86.57 to 1.98%. The major carp seed (20 - 40mm fry) alone was stocked in the reservoir with overall stocking rate of 5892 fry/ ha/ yr. The major carp production considerably increased with stocking and the maximum yield of carps was recorded at a stocking density of 8500 fry/ha/yr. It is concluded that Nagulakunta is productive reservoir in terms of fish production.
