Implications of dietary Delonix regia seed meal on growth, feed utilization, haematology and fillet yield of red Nile tilapia Oreochromis niloticus

Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing seed meal D0 = 0%; D15 15%; D20 20% D25 25% inclusion levels respectively prepared. Red tilapia (Oreochromis niloticus) fingerlings 6 weeks old acclimatized for two stocked in 12 hapas at 15 fish per hapa measuring 0.6 m × 1.2 0.7 placed a concrete tank. Each diet was assigned to separate triplicate administered 3% body weight day 16 weeks. Fish length taken initially, bi-weekly terminally. Water quality monitored weekly. Number end recorded survival rate, growth, feed utilization, fillet yield blood parameters determined. data subjected analysis variance mean separation (P= 0.05). Survival rate highest raised on least without any significant difference across range. Mean growth performances, utilization indices generally congruent between with varying degrees other feeds. Results assay did not depict harmful effects indicating that enjoyed some good measures health. gross performance optimal. It therefore concluded dietary level cooked dried flamboyant best red post fingerlings.
