EFFECT OF DIFFERENT INCLUSION LEVELS OF SHRIMP MEAL WITH FISH MEAL IN OREOCHROMIS NILOTICUS DIET

NENE AMABERE JAMABO*, CHARITY DASIMEOKUMA





 Abstract:


   A feeding trial was conducted to evaluate the effect of inclusion of different levels of shrimp meal with fish meal on growth performance, feed utilization, water quality and cost implication of the diet O. niloticus fingerlings. A total of two hundred and four (204) fish with an initial weight of 2.93+ 0.55g were stocked in twelve (12) tanks of dimension 1.8 × 1.3 × 0.36 m3 for 12 weeks. Four treatment diets (D1, D2, D3 and D4) contained 100% shrimp meal, 70% shrimp meal and 30% fish meal, 50% shrimp meal and 50% fish meal, 30% shrimp meal and 70% fish meal respectively, were fed twice daily to satiation. Final weight gain was 4.65±1.72g, 3.89±0.96g, 3.58±0.65g, 3.73±0.80g for the treatments respectively. The highest mean weight gain (4.98±0.31g) and specific (4.57±0.69%) growth rates were in fish fed with 100% shrimp meal (D1) and lowest (3.59±0.15g, 17.7±0.17% respectively) in fish fed 50% shrimp meal and 50% fishmeal (D3). Protein efficiency ratio was highest in D1 (0.13±0.00) and lowest in D4 (0.04±0.00). Feed conversion ratio was lowest in treatment diet D1 (0.60±0.10) and highest in D4 (2.01±0.20). Survival rate was good in all the treatments having the highest (89.7±3.17%) in D2 and lowest (82.4±5.02%) in D1. Diet 1 had the best growth performance followed by D2, D4 and D3 respectively. Cost implication and water quality parameters showed no significant differences (p>0.05) among the diets. Results showed that Shrimp meal could replace fish meal by 100% without having any negative effect on the growth and tend to be uneconomically efficient at such inclusion level. When included at reduced levels, it gives a good growth performance and is economically efficient.
