A 12-week feeding trial was conducted to assess the impact of fishmeal replacement with blood meal or dried porcine solubles on growth performance, body composition and intestinal morphology common carp (Cyprinus carpio). Fishmeal 50% substituted either solubles, two-third both alternative products, at a 1:1 ratio. There no significant difference in survival, final weight, weight gain ratio, feed conversion ratio condition factor between control experimental groups (p > .05), although visceral somatic index group higher than that < .05). Crude lipid content significantly soluble while other nutrient levels were not different The amino acid each from villus height fold depth lower those results this study show is optimal for growth.
