Ctenopharyngodon idella (average weight 32.0 gram) were cultured in six brick lined
(26'x12'x6') ponds for a period of six months. The stocking ratio was 7: 4: 4: 3, respectively
and the stocking density of each pond was 2508 fish/acre. Three of the six ponds served as
aerated ponds and other three as non-aerated ponds. Aeration was done with the help of
1/3 Hp vertical pump. Fish in each pond were fed with 20% protein diet@ 3% body weight.
The ponds were fertilized with cattle manure (@ 500 kg/acre) and chemical fertilizers@ 20 …
Ctenopharyngodon idella (average weight 32.0 gram) were cultured in six brick lined (26'x12'x6') ponds for a period of six months. The stocking ratio was 7: 4: 4: 3, respectively and the stocking density of each pond was 2508 fish/acre. Three of the six ponds served as aerated ponds and other three as non-aerated ponds. Aeration was done with the help of 1/3 Hp vertical pump. Fish in each pond were fed with 20% protein diet@ 3% body weight. The ponds were fertilized with cattle manure (@ 500 kg/acre) and chemical fertilizers@ 20: 2: 0 (N: P: K). Significantly high growth (P< 0.0001) and survival of fish (P< 0.0001) was observed in aerated ponds as compared to the non-aerated ponds. Pond aeration has resulted in 2095 Kg/acre more fish production with economic benefit of Rs. 144,130.
