Abstract

Background and Objective: Bonylip barb (O. vittatus) is a freshwater fish which have economic value. This study was carried out to evaluate the effect of oil enriched commercial feed on the survival and growth of O. vittatus. Methodology: Feed enriched with 9% of Shark Liver Oil (SLO), Fish Oil (FO), Corn Oil (CO) and Soybean Oil (SO) which had total fatty acid were 68.18, 86.57, 48.19 and 31.16%, respectively. The addition of different source of fat had influence on fatty acid composition of feed. The O. vittatus fingerlings performance was evaluated based on the survival and growth parameter. Results: Feed enriched with CO and SO obtained the lowest survival rate. The enrichment commercial feed with SO also displayed the lowest of weight, total length and percentage weight gain. Specific rate growth of O. vittatus fingerlings was highest with feed enriched with FO and SLO, followed by feed enrichment with CO and SO. Meanwhile, feed enrichment with SO produced the highest feed conversion ratio. Conclusion: Feed enriched with 9% of FO is good for survival, growth and feed conversion ratio of O. vittatus fingerlings.

不同脂肪源富集商品饲料对黄颡鱼鱼种存活和生长的影响

背景与目的:Bonylip barb (O. vitatus)是一种具有经济价值的淡水鱼。本试验旨在评价富油商品饲料对维塔纳图鱼(o.w itatus)存活和生长的影响。方法:饲料中添加9%的鲨鱼鱼肝油(SLO)、鱼油(FO)、玉米油(CO)和大豆油(SO)，总脂肪酸含量分别为68.18%、86.57%、48.19%和31.16%。不同来源脂肪的添加对饲料脂肪酸组成有影响。根据生存和生长参数对维氏梭子鱼鱼种性能进行评价。结果:添加CO和SO的饲料成活率最低。添加SO的富化商品饲料的体重、总长度和增重率最低。饲料中添加鱼油和SLO时鱼种的特定生长速率最高，其次是添加CO和SO。同时，用SO富集饲料可获得最高的饲料转化率。结论:添加9%鱼油的饲料有利于维氏梭子鱼鱼种的生存、生长和饲料转化率。
