Ex-situ Studies of Captive Breeding of Ompok bimaculatus (Bloch, 1794) in Tripura

Brood stock (37 males and 83 females) of Ompok bimaculatus was sampled from Rivers Feni, Muhuri, Gomoti, and also from Hurijala wetland of Tripura during November 2008 to February 2010. During sampling of fish species, water samples from different locations were also sampled in order to know the water quality characteristics of the habitat. The brood stock was provided specific live feed and water quality during acclimatization. The maturity cycle of the species was examined with gonad during the monsoon period. During breeding season the gravid females and males were identified with some specific phenotypic characteristics. Induced spawning was done under some particular aquaculture conditions only.
