Abstract
This study was carried out to investigate the effect 01 level of poultry manure and stocking density on growth performance of silver carp (HypophMalmichtnys mollate. Six recangle earthen ponds, each of a total area of about 0.25 leddan (50 x 20 m) representing six treat-mans (3 levels of poultry manure 150. 300 and 450 kgneddarVweek within each two stocking densities 3200 and 4800 fisMeddan), were used In this study. The experiment expanded 20 weeks. Results obtained showed that average body weight and body length of silver carp fish during the experiment increased with increasing poultry manure levels and the increase was more pronounced at lower slacking density (3200 s !VI eel de n ). Analysis of variance showed that the differences between average body weight and body length were sig­nificant (bc0.05). Other growth performance parameters are also dis­cussed. In general, results indicated that body weight of silver carp in­creased within each manuring level as the stocking density decreased the increase in this trait was more pronounced at higher manuring lev­els. The same trend was observed for body length. Body weight gain in­creased with increasing manuring level. The results indicated that fish grow better at lower stoking density (3200 fish/fed). The results indi­cated that increasing manuring level results in an improvement in SGR. Increasing stocking density led to decrease SGR. Generally. the results indicated that level of manuring and stocking density seemed to have no influence on condition factors.
