Effect of Different Feed Application Rates on G rowth Performance and Body Composition of African catfish, Clarias gariepinus fingerlings
Journal Title: International Journal of Scientific Research and Management - Year 2013, Vol 1, Issue 9
Abstract
This Study was carried out in the Institute of Oceanography Fish Farm which is geographically located in the historic peninsula of the Great Kwa River. This study lasted for ten weeks and was carried out in 3 hapas (A 1 , A 2 , and A 3 ) measu ring 1.5 x 1.0 x 1.0 m 3 in earthen pond. A total of sixty (60) fingerlings of Clarias gariepinus , mean bulk weight 0.20 ± 0.02 kg (10 g for each fingerling) were collected from the University of Calabar fish farm and stocked in each of the three experiment al units (20 in each unit). The fishes were fed twice daily at 3%, 8% and 12% of their body weight. Some physicochemical parameters (Dissolved oxygen, pH, Ammonia and Temper ature) of the water were measured weekly with a calibrated electronic meter. Mean t emperature, pH and ammonium were found not to be affected by feed application rates during the ten weeks feeding trial. However, dissolved oxygen levels increased significantly with i ncreasing feed application rate. The food values analyzed showed varied v alues of their presence in the body tissue of the fish analyzed; with the mean moisture, carbohydrate and protein recording higher value in that order; followed by ash, fat and fibre. The fish samples pre sented a relatively higher and lower amount of proxi mate concentrations. Growth performance and proximate composition of Clarias gariepinus show no significant differences among different feed application rates. The results suggest that, although a feeding rate of 12% gave the highest growth performance, Cl arias gariepinus should be fed at the rate of 8% body weight per day, considering feed conversion efficiency, survival rate and growth response
