Aim: The present study was undertaken to find out the possibilities of induced breeding of Catla catla, at low water temperature using fibre reinforced (FRP) tanks in a carp hatchery.    


Methodology: Brood fish of C. catla was maintained in 0.1 ha pond with proper feeding and pond management. Six induced breeding programmes: 3 in April (pre-monsoon) and 3 in June (monsoon) of 2017 were conducted with C. catla using synthetic hormone, Ovasis intra-peritoneally. The relationship between temperature variation and latency period, effective spawning period, fecundity, hatching start time, hatching duration and spawn production with its recovery was observed.


Results: The latency period (time gap between injection and first egg release) was very high and ranged between 653.3 and 721.6 min for breeding in the pre-monsoon and ranged between 446.6 and 480 min for monsoon period. In pre-monsoon, the effective spawning period between 86.6 and 116.6 min and in monsoon between 53.3 and 73.3 min; both varied significantly (p˂0.05). In pre-monsoon period, the average water temperature during larval incubation in hatching pool ranged between 21.58 and 22.58?C, whereas during monsoon period it ranged between 30.1 and 30.4?C. The spawn production was 0.13 to 0.22; and 0.47 to 0.65 (lakh kg-1 b. wt. of female) in pre-monsoon and monsoon period, respectively, and showed a significant difference (p˂0.05).               


Interpretation: This report on breeding of C. catla in the temperature range of 18.6-24.7oC indicates the possibility of spawn production of Indian Major Carp in the north east hilly region states of India


Key words: Catla catla, FRP carp hatchery, Induced breeding, Low temperature, Latency period, Spawn production
