Effects of Fish Feed Carbohydrate Sources on the Floatation and Water Stability of Fish Feed Pellets

Abstract

Three feeds were formulated to carry out a study on the floatation test and water stability tests of fish pellets. The feeds were formulated using different sources of carbohydrate (Maize, Guinea corn and Wheat). After 30 minutes of exposure to water, Guinea corn maintained 90% of floating pellets while the other two sources had 80% floating pellets respectively. There were significant differences in the percentage number of pellets floating between 0 and 30 minutes (P<0.05). There were also significant differences in the water stability of the pellets, between 10 and 30 minutes. Wheat had the highest water stability of 87.8% while Maize had 75.4% water stability and Guinea corn had the lowest percentage of 71.6% but after 50 minutes Maize had the highest percentage of 61.8% and Guinea corn had the lowest percentage of 52.4%.

Keywords: Carbohydrate sources, Floating ability and Water stability.
