Optimisation of stocking density of Thai silver barb (Barbodes gonionotus Bleeker) in the duckweed-fed four species polyculture system
The optimisation of stocking density of Thai silver barb (Barbodes gonionotus) in the polyculture with Labeo rohita, Catla cat/a and Cyprinus cmpio was investigated in seasonalponds. Three different stocking densities of Thai silver barb i.e., 5,000, 6,000 and 7,000fingerlings ha-1 were tested with stocking density of carps fixed at the rate of 10,000fingerlings ha-1 Duckweed was applied to all ponds supplemented with rice bran and oilcake. There were no significant variations on either water quality parameters orabundance of planktonic organisms due to the different stocking densities of silver barb.A significantly higher fish production (p<O.OS) was recorded in the ponds in whichmedium stocking density of Thai silver barb was maintained.
