Polyculture of gulsha (Mystus cavasius Ham.) with rajpunti (Puntius gonionotus Bleeker) and silver carp (Hypophthalmichthys molitrix Val.) in earthen ponds
Culture of gulsha (Mystus cavasius) with rajpunti (Puntius gonionotus) and silver carp ( Hypophthalmichthys molitrix) was undertaken to assess the growth and production potential of these species under polyculture system. Fingerlings of gulsha, rajpunti and silver carp were stocked at a density of 18.000, 10.000 and 4.000/ha respectively. Two treatments were tested in this experiment. Treatment-I was conducted with rice bran and mustard oil cake and treatment-II with rice bran and duck weed. All the ponds were fertilized with urea and TSP at fortnightly intervals. After six months' rearing, the gross production was estimated to be 3,582 and 3,125 kg/ha from treatment-I and treatment-II respectively. Total yield showed non-significant differences (P>0.05) between the treatments.
