| Abstract | Dry fish blood (DFB), a by-product from the fish processing industry, is a rich source of nutrients, small proteinmolecules and iron. This study aimed to examine the effects of dietary inclusion of canning by-product fish blood on growthperformance and activity of digestive enzymes in L. vannamei with mean initial weight of 4.79?0.12 g. Six diets wereformulated: four diets having poultry meal and soybean meal as the main protein sources contained DFB at 0 (control), 4, 8, and16% of diet and the reference diets5 and 6contained 4% tuna viscera hydrolysate (TVH) and 16% fish meal, respectively.Triplicate groups of shrimp (12 shrimp tank-1) were fed with respective diets five times daily for six weeks. The results showedthat growth of shrimp decreased with increasing level of dry fish blood. Growth performance of shrimp fed 4% DFB was notsignificantly different from those fed 4% TVH. Survival rate was not significantly different among treatments (P>0.05). Insummary, dry fish blood could be used as a feed ingredient in shrimp diet at 4% of diet with good growth performance. Theresults demonstrated that the high levels of dry fish blood had an effect on feed utilization efficiency, alkaline phosphataseactivity and shrimp growth reduction. |
