Abstract:
The present investigation was carried out to study the seed rearing and survival of silver barb (Puntius gonionotus) in cement cisterns under monoculture with varying stocking density. Study was carried out for a period of 90days in twelve number of cements cisterns with 21m3 area (7×3×1) m. Four different stocking density such as; 0.2 million/ha,0.4million/ha,0.5 million/ha and 0.6million/ha in T0, T1, T2 and T3 having three replicas for each respectively. The initial average weights of the species were 0.74±0.04 g, 0.75±0.07 g, 0.87±0.05 g and 0.75±0.07 g respectively in T0, T1, T2 and T3. Fishes in all experimental cement cisterns supplemented with ground nut oil cake and de-oiled rice bran (1:1) at a rate 10% of their biomass throughout the culture period. Water quality parameters were within a suitable range for fish culture in cement cisterns. At the end of experiment, the treatment means which differ significantly is done by computing the critical difference (CD) of randomized block design. The difference between the treatment means T0 and T1, T0 and T2, T0 and T3, T1 and T2, T1 and T3 is more than the CD value indicating the significant difference between these treatments. It is concluded that Puntius gonionotus is a suitable fish species for seed rearing in cement cisterns for better growth and survival with stocking density varies from 0.2 million/ha to 0.4 million/ha.
