Abstract

The chemical and nutritional assessment of tiger nut (Cyperus esculentus) used as feed additives on the feed of African catfish (Clarias gariepinus) was investigated. The fingerlings of C. gariepinus were assigned randomly into 3 replicate aquaria at 15 fingerlings per treatment and fed at 3% of their body weight twice daily. The proximate composition showed that dry tiger nut had 4.63% moisture content, 2.89% ash, 26.73% lipid, 7.65% crude fibre, 6.92% crude protein and 58.84% carbohydrate. The mineral analysis on the other hand showed that the tuber of C. esculentus is made up of sodium (247 mg/100g), potassium (193 mg/100g), calcium (136 mg/100g), manganese (21.3 mg/100g), magnesium (18.3 mg/100g) and iron (0.91mg/100g). Fish feed experimental diet III showed significantly higher increase in length from the initial week 1 and week 2 (p<0.05). Fish feed experimental diet III showed significantly higher increase in length from the initial week, week 1 and week 2 (p<0.05). Fish fed experimental diets I and II had significant feed conversion efficiency (p<0.05) compared to control diet.
