Title : Captive breeding of indigenous Sophore barb (Puntius sophore) for ornamental trade and nutritional security
Abstract:
Cyprinids are potential candidate species in the aquarium trade as well as nutritional security and standardization of breeding technique is a sustainable method to reduce pressure on natural stock. In the present study, fish species were collected from North-East India and brought to South part of India to develop and implement breeding technology for sustainable supply and conservation. The breeding trials were conducted using synthetic hormones viz. Wova-FH, Human Chorionic Gonadotropin (HCG) and Ovatide at various doses. Results confirmed that P. sophore bred successfully after intra-peritonial injection of WOVA-FH at 0.4 mL kg-1 to female and 0.3 mL kg-1 to male with higher fecundity (881.50±85.8), fertilization (78.50±2.72%) and hatching rate (83.75±2.39%). Developmental stages like morulation, blastulation, gastrulation, bud formation and hatching were observed at 1:45-, 2:45-, 5:30-, 11:00- and 72:00 hrs post-spawning (hrs), respectively. The present study offers breeding technique using synthetic hormone and provide insight on embryonic developments which will have significant implications on conservation and seed production for aquariculture.
Key words- Breeding, Conservation, Embryonic development, Puntius sophor, Synthetic hormone.
