Abstract:
Background and Objective: Eco-climatic condition is highly favorable to conduct the aquaculture farm operation in Riverine Bangladesh and recently aquaculture became a profitable and nutritious source of agriculture and this study conducted to enhance the production of small indigenous fish with carps in Bangladesh. Materials and Methods: An on-farm experiment was carried on 240 days during April-December, 2012 at North-west Bangladesh to produce more small fish with the carps. All of the household ponds (200-600 m2) were stocked with the fingerlings of Labeo rohita, Catla catla, Cirrhinus cirrhosus, Hypophthalmichthys molitrix, Ctenopharyngodon idella, Labeo bata and Amblypharyngodon mola at different rate. There were three treatments and interfering the period of culture varied the production frequency of mola which produced more or less in the experimental ponds. Results: All the recorded water quality parameters varied significantly differences (p>0.05) among the treatments except transparency and dissolved oxygen. The growth performance of all the carps, silver carp was the first growing and bata was the lowest. The total fish production was the highest (3783.30 kg ha1) in early stocking (EST) and the lowest (2836.61 kg ha1) in existing stocking (EXST) treatment, but the total small fish production (55%) was higher in the EXST ponds than seasonal stocking (SST) and EST ponds. The highest SGR and the rate of survival of carps were higher in SST than the other treatments. Conclusion: Poly-culture of carps with mola can provide additional nutritional and economic benefits; field level household culture is highly suggested in Bangladeshi pond.
