通过对黄鱼桑鱼消化道指数和消化道内食物组成的研究表明，黄鱼桑鱼系肉食性鱼类，主要以小型水生动物为食。胃、肠的ｐＨ值分别为３．８～４．６、６．５～８．５。同时，胃、肠的蛋白酶和淀粉酶活力性较强，经池塘网箱养殖２８ｄ后，其胃、肠的蛋白酶和淀粉酶活性明显增加，表明黄鱼桑鱼具有较强的消化能力。通过对全鱼和肌肉常规营养成分和氨基酸的分析结果表明，黄鱼桑鱼为一种营养价值较高的优质鱼，具有较大的开发价值，是人工养殖的优质鱼类
The study on the digestive tract index of the yellow croaker and the food composition in the digestive tract showed that the yellow croaker mullet is a carnivorous fish mainly feeding on small aquatic animals. Stomach, intestinal pH values were 3.8 ~ 4.6, 6.5 ~ 8.5. At the same time, the activity of protease and amylase in stomach and intestine was stronger. The protease and amylase activities in stomach and intestine increased significantly after 28 days of culture in pond cages, which indicated that the fish had good digestibility. The results of routine nutrition analysis and amino acid analysis of whole fish and muscle showed that the yellow mulberry was a kind of high-quality fish with high nutritional value and had great development value. It was a kind of high-quality cultured fish
