  Clarias gariepinus has been identified as a candidate that will help to bridge the gap between demand and supply in fish protein in Nigeria due to its suitability for aquaculture in Nigeria. Feeding therefore forms a very high proportion of production cost of this fish especially in concrete ponds where there is total dependence on food supply by farmer. Blue crown feeds were investigated to know its influence on some growth parameters. The mean weight gain in the fish was 715.12 g for males in 120 days. That of females was 734.7 g within the same period. The average daily weight gain for males was 5.96 g/day and that of females was 6.12 g within the period. The specific growth rate for males and females were 2.20 and 2.21 respectively. An increase in length of males and females fish in 120 days was 36.3 cm and 36.7 cm respectively. The fish population exhibited jumpers’ phenomenon as the fish final range was 400g - 850 g in weight and 37 cm - 45 cm length. However, the specimens formed a population that was normally distributed, this jumper’s was minimal. There was absence of cannibalism in the pond because only one fish died possibly by natural cause. There was a positive allometric growth as the condition factor; K of the fish was greater than 1. Though blue crown has a price which is 0.5 time lower than COPPENS, its effects on growth parameters are optimal and is recommended as a feed of choice for Clarias gariepinus culture in Nigeria.
