The present study was carried out to evaluate the breeding performance of riverine rohu Labeo rohita and growth performances of F1 progenies reared in hapas. Two reciprocal crosses of brood fish from Halda and Padma rivers: Halda X Padma ‚ (cross 1) Padma X Halda ‚ (cross 2) and one parental cross (cross 3 control): Hatchery X Hatchery ‚ were obtained in the present study. After 3 days of hatching the spawns were transferred and reared in hapas for 107 days to observe growth performances in terms f weight and length. Cross 1 and cross 2 showed lower fertilization rates of 86 and 83 and hatching rates of 66 and 61 respectively compared with 90 fertilization rate and 71 hatching rate of cross 3. Growth performance study revealed no significant differences (p 0.05) in weight and length between the reciprocal and parental crosses. The Halda X Padma ‚ and Padma X Halda ‚ crosses showed higher weight of 4.64 g and 4.56 g and length of 8.63 cm and 8.11cm respectively compared with 4.47 g and 7.55 cm of parental cross. Fry survival rates in hapas 1 2 3 4 5 6 7 8 and 9 were 31.253.18 37.503.21 33.331.57 31.253.18 29.410.99 25.000.78 26.670.87 25.000.67 and 23.530.02 respectively.

Abstract

The present study was carried out to evaluate the breeding performance of riverine rohu Labeo rohita and growth performances of F1 progenies reared in hapas. Two reciprocal crosses of brood fish from Halda and Padma rivers: Halda X Padma ‚ (cross 1) Padma X Halda ‚ (cross 2) and one parental cross (cross 3 control): Hatchery X Hatchery ‚ were obtained in the present study. After 3 days of hatching the spawns were transferred and reared in hapas for 107 days to observe growth performances in terms f weight and length. Cross 1 and cross 2 showed lower fertilization rates of 86 and 83 and hatching rates of 66 and 61 respectively compared with 90 fertilization rate and 71 hatching rate of cross 3. Growth performance study revealed no significant differences (p 0.05) in weight and length between the reciprocal and parental crosses. The Halda X Padma ‚ and Padma X Halda ‚ crosses showed higher weight of 4.64 g and 4.56 g and length of 8.63 cm and 8.11cm respectively compared with 4.47 g and 7.55 cm of parental cross. Fry survival rates in hapas 1 2 3 4 5 6 7 8 and 9 were 31.253.18 37.503.21 33.331.57 31.253.18 29.410.99 25.000.78 26.670.87 25.000.67 and 23.530.02 respectively. Hapa 2 showed the highest survival and yield whereas hapa 9 showed the lowest survival and yield.
