Abstract
During September 2009 to August 2011 brood stock of Ompok bimaculatus was collected from different water bodies of Tripura such as Rivers Feni, Muhuri, Gomoti, and also from Rudrsagar and Hurijala wetlands. To maintain certain water quality characteristics in the breeding program water samples from different locations were collected. The brood stock was provided specific feed during acclimatization. With certain characteristics of the gonad the maturity cycle of Ompok bimaculatus was examined during June-July. With some specific biological conditions the induced spawning was done. Developments of embryonic and larval developmental stages of O. bimaculatus were marked with some specific characteristics features.
