Abstract
The use of coconut meal may represent an alternative source to fish feeding. The purpose of this work was to assess the impact of the use of coconut meal in Nile tilapia feeding and on the nutritional value of the fish fillets. The experiment was conducted in a completely randomized design with 4 treatments (T1 - 0%, T2 - 10%, T3 - 20%, and T4 - 30% for the inclusion of coconut meal) with five repetitions. The proximate composition, cholesterol, and fatty acids were determined. There was a difference (p < 0.05) between the treatments T1 and T3 and between T2 and T3 with regard to moisture levels; between T2 and T3 with regard to lipids; T1 and all the other treatments with regard to carbohydrates, and finally between T1 and T2 and between T3 and T4 with regard to ash. The cholesterol level showed a significant gradual increase following the increase in the inclusion of coconut meal. There was also a difference (p < 0.05) between the treatments concerning the following fatty acids: C10:0; C12:0; C14:0; C18:1; C18:3 (gama); C20:3 , and C22:6 , but the nutritional quality of the product was not affected.
