Resumo

Pangasius sutchi were artificially bred for determining the hatching success and larval growth response to live food in relation to varying stocking densities. The fertilized eggs were hatched out with successful hatching rates ranging between 60 and 63%. Newly hatched larvae of 4.4 mm average length were reared using Tubifex as live food in metallic trays with water temperature of 27 to 29.5°C and dissolved oxygen level of 3.88 to 6.22 mg/1 for 6-day with an average survival rate of75.56±13.25%. The P. sutchifry of9- day old were further reared using Tubifex in the polythene covered metallic trays at the stocking densities of 2-7 fry per litre of water for a period of 14 day. P. sutchi fry raising at 4 individual per litre of water for 14 day gives better results in terms of survival and growth.
