abstract
The study has been carried out to study the Impact of Labeo rohita (Hamilton) Fingerlings Feeding Probiotic (Proteus) on selected water quality parameters. For pursuing such type of research probiotic (Proteus) have been taken as growth promoting ingredients in the traditional carp feed i.e. rice bran, groundnut cake, fish meal and mineral mixture for the rohu (Labeo rohita) fingerlings. These above four feed ingredients have been mixed with conventional carp diet at 2g/kg of feed, 3g/kg of feed, 4 g/kg of feed and 5g/kg of feed levels respectively. During the experimental period of 60 days, the fingerlings of rohu (Labeo rohita) were fed @ 4 % of their body weight per day.
