  Aquaculture wastewater collected from a catfish farm in Ibadan metropolis was treated with duckweed, Lemna minor (Td) for two weeks and thereafter used in the culture of Nile tilapia (O niloticus). The performance of O niloticus raised in Lemna minor treated waste water was compared with bacteria-treated waste water, Bacillus sp. (Tb) and well water (Tc) as control (untreated). The Bacillus sp. was isolated from the catfish wastewater, and was positive to Gram’s staining, catalase and glucose fermentation test. Nile tilapia juveniles (n=54) of an average initial weight of 10.43 ± 0.04 g were stocked in triplicates per treatment and fed to satiation twice daily for 8 weeks. There was significant difference (P<0.05) in the quality of waste water in all the treatments. Compared to initial waste water, Td showed a significant reduction in biological oxygen demand, BOD (1.2.. View More»
