Abstract

A Comparative Study of the Growth Performance and Food Utilisation of the African Catfish (Clarias gariepinus) Fed Unical Aqua Feed and Coppens Commercial Feed

Growth performance of African catfish, Clarias gariepinus fed Unical Aqua feed was carried out as a comparative study with Coppens commercial feed for six months in concrete tanks. Triplicate group of 50 post fingerlings with a mean bulk weight of 0.50 ± 0.02 kg were stocked in three circular concrete tanks, area 16.63m2 labelled A1, A2, A3, B1, B2 and B3. Fish in units A1, A2 and A3 were fed Coppens feed while fish in units B1, B2 and B3 were fed Unical Aqua feed twice daily at 3% of their body weights. Growth performance indices showed that weight gain (kg), growth rate (GR), specific growth rate (SGR) and mean growth rate (MGR) of C. gariepinus fed Unical feed was significantly different (P<0.05) from fish fed Coppens feed.
