Fisheries of a minor reservoir, Shathamraj,

The present study based on the data for 10 years deals with the role of a minor reservoir in fish production and the influence of stocking densities on fish produc-tion. Shathamraj, a minor reservoir with 25 ha of water spread is located in Hyderabad. The reservoir is treated as stocking and capture system for develop-ment of the fisheries. The overall major carp production is 456.88kg/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 Shathamraj is a highly productive reservoir in terms offish production
