Biogas plant-effluent as an organic fertilizer in monosex, monoculture of fish ( Oreochromis mossambicus)

Effluent collected from a KVIC model biogas plant fed on cattle dung was utilised in monosex (all male), monoculture of the fish Oreochromis mossambicus, at field level in 0.002 ha ponds. Biogas-plant effluent was supplied at 0.15% (W/V) concentration level at 3 day intervals. No supplementary feed...

Description
Summary:Effluent collected from a KVIC model biogas plant fed on cattle dung was utilised in monosex (all male), monoculture of the fish Oreochromis mossambicus, at field level in 0.002 ha ponds. Biogas-plant effluent was supplied at 0.15% (W/V) concentration level at 3 day intervals. No supplementary feed was given for the fishes grown in biogas plant effluent. Oreochromis mossambicus attained a maximum weight gain of 0.67 g fish −1 day −1. Growth rate was independent of stocking density upto 60 000 fish ha −1. Total maximum fish production was 4826 kg ha −1 in 125 days.
