Abstract:

Portable Fiberglass Reinforced Plastic (FRP) pabda hatchery consisting of three incubation pools and three rearing tanks having capacity to accommodate about 45,000 - 50,000 nos. fertilized eggs and to produce about 10,000 – 15,000 nos. of early fry of Ompok bimaculatus (pabda) in a single cycle was developed, established and operated at Kalyani Field Station of RRC-Rahara of ICAR-CIFA. Four different induced breeding experiments were conducted using 14 pairs of pabda brooders (female: 120.75 ± 39.25 g and male: 68.89 ± 15.92 g) in the established hatchery between August and October, 2019 using synthetic hormone Ovatide. Brooders were injected within 8-12 hrs of harvest to ensure proper acclimatization and also to avoid stress due to long time confinement. Females and males were injected with hormone @ 1.5 ml and 0.75 ml per kg body weight, respectively. Latency period was 8.5-10 hrs and relative fecundity ranged from 131-186 eggs/g body weight of female. Rate of fertilization achieved was 72.57 ± 6.62% at water temperature range of 25-27°C. Fertilized eggs were distributed in the FRP incubation pools and maintained for hatching in two different flow-through systems (feeble water circulation + aeration, and feeble water shower + aeration). Eggs hatched out between 22–27 hrspost fertilization (hpf) at water temperature of 26.67 ± 1.58°C, with no clear difference between the two systems. Though not statistically significant, average rate of hatching were observed little higher in system with feeble water shower and aeration (65.25 ± 7.71%) than feeble water circulation and aeration (64.20 ± 9.47%). Yolk-sac of newly hatched larvae (measured 3.8 – 4.5 mm in length) got absorbed within 60 hpf. A total of approximately 43,000 nos. seeds after 7 days of hatching with hatchlings survival rate of 43.8 to 58.5% were achieved.
