Comparative assessment of fermented maize broth and cassava waste water on the growth performance of catfish (Clarias gariepinus) fry
The study was conducted to evaluate and compare the growth performance of catfish fry on fermented maize broth and cassava waste water. Four day old fry (weight range 0.002 - 0.003g) of C. gariepinus were acclimatized in 10 litres glass tank of water for 5 days in Aquaculture Department of Nigerian...

| Summary: | The study was conducted to evaluate and compare the growth performance of catfish fry on fermented maize broth and cassava waste water. Four day old fry (weight range 0.002 - 0.003g) of C. gariepinus were acclimatized in 10 litres glass tank of water for 5 days in Aquaculture Department of Nigerian Institute for Oceanography and Marine Research, Victoria Island, Lagos. Shell free artemia was mixed with Fermented Maize Both (FMB), Fermented Cassava Waste water (FWC) and bore hole water (control) respectively. The artemia mixtures were allowed to air-dry before administration. The treatments were produced in triplicates, feeding, ad-libitium for 30 days. The fry were fed with the treated shell free artemia and weighed every 6 days. The results revealed that fry fed fermented cassava waste water [FCW] diet showed highest mean weight, daily growth rate [DGR], survival rate and specific growth rate [SGR] and lowest food conversion ratio (FCR). This was followed by fermented maize broth while fish fed artemia mixed with borehole water-had the least growth. The results suggest that addition of fermented cassava waste water to shell free artemia can enhance fish growth in catfish hatchery production. |
