Abstract：
The fish diet is one of the essential factors in the development of aquaculture. The purpose of present study was to evaluate using grape pomace as a main feed ingredient on growth performance, body chemical composition, survival rate, and morphological indices of the carp (Cyprinus carpio). 200 fish with an average weight of 7 ± 0.4 g were randomly distributed in four tanks for total of 56 days. The fish were fed with a diet containing 5%, 10%, and 15% grape pomace in different feeding groups designated as G1, G2, and G3. The average daily weight gain (g), weights gain (g), and specific growth rate (%) were significantly higher (p < .05) in G3 as compared to G1 and G2 groups. The lowest feed conversion ratio was recorded in G3 group. The morphological indices, condition factors, viscerosomatic index, and hepatosomatic index were significantly higher in G3 group as compared to other treatments. The protein, fat, moisture, and ash contents in the C. carpio fillets were significantly influenced by feeding rate. The results showed that grape pomace had a positive effect on growth, survival, and nutritional indices in the carp fish. According to the obtained results, grape pomace (150 g/kg food) can be considered as the diet component for the carp fish.
摘要：
鱼类饮食是水产养殖发展的重要因素之一。本研究的目的是评估使用葡萄果渣作为主要饲料成分对生长性能的影响。身体化学成分，存活率,和鲤鱼（Cyprinuscarpio）的形态指标。将200条平均重量为7±0.4g的鱼随机分布在四个罐中，共56天。鱼的饮食含有5％，10%,不同饲喂组的葡萄果渣分别为G1、G2和G3。平均每日体重增加（g），体重增加(g)，与G1和G2组相比，G3组的特定生长率（％）显着更高（p<0.05）。G3组的饲料转化率最低。形态学指标，条件因素，脏腑指数，G3组肝细胞指数明显高于其他治疗组。蛋白质,脂肪，水分,饲喂率显着影响C.carpio鱼片中的灰分含量。结果表明,葡萄果渣对生长有积极作用,生存,和鲤鱼的营养指数。根据得到的结果,葡萄果渣(150克/千克食物)可以被认为是鲤鱼的饮食成分。
