Effect of Pond Fertilization with Vermicompost and Some Other Manures on the Growth Performance of Indian Major Carps
Sunita Godara, Ram C. Sihag and Rajender K. Gupta

Abstract:
Vermicompost is one of the ready to use organic fertilizers. The efficacy of vermicompost vis-a-vis other organic fertilizers for fish production has not yet been extensively explored. For this purpose, an experiment was performed on three Indian major carps viz. catla (Catla catla Ham.), rohu (Labeo rohita Ham.) and mrigal (Cirrhinus mrigala Ham.). The fry/fingerlings acclimated for 10 days prior to the commencement of experiment were stocked in 5.54x6.15 m size ponds with a stocking density of 30 fish per pond in a ratio of 3:4:3, respectively. Six treatments viz. a control (T1) without any treatment, pig manure at 4,000 kg ha-1 year-1 (T2), poultry manure at 6,000 kg ha-1 year-1 (T3), cow dung at 10,000 kg ha-1 year-1 (T4), vermicompost at 10,000 kg ha-1 year-1 (T5) and vermicompost at 15,000 kg ha-1 year-1 (T6) were used and their effect on growth performance of these fishes was recorded every month for a period of one year. All the six treatments caused significant monthly increase in fish growth; the three fish species gained maximal growth (length and weight) in ponds treated with vermicompost at 10,000 kg ha-1 year-1 (35.6 cm, 900.5 g; 36.8 cm, 935.0 g; 35.2 cm, 879.0 g), followed by vermicompost at 15,000 kg ha-1 year-1 (31.8 cm, 880.8 g; 32.1 cm, 910.2 g; 33.2 cm, 860.2 g), cow dung at 10,000 kg ha-1 year-1 (28.7 cm, 835.7 g; 29.3 cm, 850.7 g; 30.1 cm, 783.0 g), poultry manure at 6,000 kg ha-1 year-1 (26.5 cm, 768.7 g; 27.4 cm, 792.2 g; 28.9 cm, 760.9 g), pig manure at 4,000 kg ha-1 year-1 (25.1 cm,718.1 g; 25.9 cm, 732.9 g; 26.8 cm, 693.8 g) and the control (21.7 cm, 645.5 g; 22.0 cm, 606.2 g; 23.1 cm, 591.2 g), respectively; the differences between treatments were significant. Among the three species, Labeo rohita attained the maximal growth (length and weight) (36.8 cm and 935.0 g) followed by Catla catla (35.6 cm and 900.5 g); Cirrhinus mrigala showed the minimal growth (35.2 cm and 879.0 g). Pond fertilization with vermicompost at 10,000 kg ha-1 year-1 (in split doses) seemed to be the optimum dose for the maximum growth of Indian major carps.
