以半滑舌鳎为试验对象,进行为期90天的摄食生长试验,比较研究不同饲料对半滑舌鳎摄食、生长饲料利用的影响。试验选择2种商业饲料,一种是品质已获得市场认可的亚洲某知名品牌饲料,另一种为国家鲆鲽类产业技术体系研发的国产优质高效饲料—七好饲料。结果表明:七好饲料组半滑舌鳎的增重量、增重率和特定生长率均明显比亚洲某知名品牌饲料组高,七好饲料组的饲料效率较高,饲料系数较低,表明其饲料利用效率更高。
The half-smooth tongue 鳎 as the test object, a 90-day feeding growth test, a comparative study of different feed on the smooth tongue 鳎 feeding, the growth of feed utilization. Two types of commercial feed were selected for trial. One is a well-known brand of feed approved by the market in Asia, and the other is a high-quality domestic feed developed by the national technology system of flounder and shrimp. The results showed that the weight gain, weight gain rate and specific growth rate of the semi-smooth tongue plovers of the seven good feed groups were significantly higher than those of a well - known brand feed in Asia. The feed efficiency of the seven good feed groups was lower and the feed coefficient was lower, indicating that the feed utilization efficiency higher.
