Between October 2000 and March 2001, a preliminary study on the aspects of the biology of Parachanna obscura, was investigated. Sex ratio revealed female preponderance [X2=4,7338, df =1, p2 = 4.735, df = 1, p = 2697,n= 408, r = 0.869, [pC. obscura [size range 9.0 18.0 cm comprises food items. The items were re-classified into seven major groups consisting of detritus [coarse fine detritus], fish juvenile and remains of fish], Insecta [un-identified adult and remains of insects, macrophyte materials, mud, Oligochoetes [earth-worm], and abiogenic sand. Fish, insects Oligochoetes were eaten as primary foods items. There was a complete ingestion of the array the dietaries by both sexes. Exception of one item [coarse detritus] during the wet season, P. obscura consumed all the dietaries during the seasons. Nevertheless, the later season increased in the ingestion of 9 out of the 10 items in conformity with optimal foraging theory. Parachal obscura is considered as piscivore-insectivore-invertivore in feeding habits. In the wake of doubts about the viability and prospects of aquaculture, farming of P. obscura is a possibility. This species possesses a number of positive attributes with regards to aquaculture. It is likely that efforts to culture this hardy carnivorous and fast-growing fish will spread in the coming years in Nigeria, breeders and fish farmers will likely give it a chance
