Abstract
The culture potential of Sperata seenghala was investigated in captive conditions. The fingerlings of S. seenghala were collected from Sajawal, Thatta, Sindh. The fish were air lifted to the NARC, Islamabad in oxygen-filled polyethylene bags with three sedative doses (20, 30 and 40 mgL-1) of tricaine methane sulphonate (MS222) at two loading densities (50 and 75 fish per bag). The maximum survival of 90.66% was observed in fingerlings transported with sedative doses of 30mgL-1 at loading density of 50 fish per bag. The fingerlings were acclimatized in circular tanks and concrete raceways. The survival and growth performance during the acclimatization period was better in concrete raceways compared to circular tanks. The cannibalism behavior was studied by the segregation of fish into four groups on the basis of their body weight while the fifth group was mixed size fish (control). A significant difference (p<0.05) of survival rate was observed among the segregated groups and mixed size fish. It was concluded that water and oxygen-filled polyethylene bags having 30 mgL-1 of MS222 were effective for the live transportation of giant river catfish fingerlings. The fingerlings of giant river catfish were successfully acclimatized in captivity by segregating it on the basis of size.
