Abstract
A study was conducted to study the effects of feed on survival and growth of local sarpunti (Puntius sarana) fry in nine glass aquaria (45 x 25 x 24 cm) for a period of 35 days in the Wet Laboratory of Fisheries Faculty, Bangladesh Agricultural University, Mymensingh. Each glass aquarium contained 10L of tap water and the stocking rate was 6L-1 of water. Three feeding treatments such as live feed (Plankton, 8,700/L), SABINCO feed containing 25% protein and formulated feed containing 30% protein were used for T1, T2 and T3, respectively. Each treatment had three replications. The growth performances in terms of length gain, weight gain and SGR (%/day) were 19.1±0.1 mm, 81.5±2.9 mg and 9.9±3.1 respectively in case of Ti and it was followed by T3 (10,9±0.1, 13.5±1.1 and 5.3±1.7, respectively) and T2 (7.8±0.4, 10.2±0.8 and 4.6±1.7, respectively). The highest survival rate was also found in Ti (77%) while the lowest in T2 (56.1%). Ti showed significantly (p<0.05) higher health condition (3.4±1.3) followed by T3 and T2 (1.3±0.1 and 1.2±2.1, respectively) but T2 and T3 did not differ significantly (p<0.05) from each other.
