Breeding of endemic catfish, Horabagrus brachysoma in captive conditions

Abstract

Horabagrus brachysoma, popularly known as golden catfish, is an endemic species in the Western Ghat rivers of peninsular India. Breeding of this catfish was successfully accomplished in captive condition. Induced fishes responded well and spawned naturally in 8–14 h and the fertilized eggs hatched in 22–29 h.Artificial fertilization by stripping was also successful when carried out within 1–2 h of the latency period after hormonal manipulation. Seed rearing was successfully accomplished in earthen ponds. This opened up opportunities for mass production of seeds of this species for restoration, stocking and conservation. Consequent to introduction of hatchery reared seeds produced by these techniques into natural waters, the species is now on a comeback trail.
