栉孔扇贝(Chlamys farreri)是一种重要的海产经济贝类。闭壳肌的干制品俗称“干贝”,其肉质细嫩,味道鲜美,营养丰富。据分析,在一百克食用部中,含蛋白质63.7%,脂肪3%,碳水化合物15%。在我国分布于黄、渤海沿岸,是我国近年来发展增养殖的一种重要珍贵种类。随着扇贝增养殖的发展,对苗种的需要量愈来愈大,但在目前海区天然资源贫乏,人工养殖数量又很少,大多数海区尚未具备天然采苗的条件下,人工育苗仍然是近年内解决苗种来源的主要手段。我国自1974年人工育苗试验成功以来,扇贝人工育苗已经有了很大发展,目前全国已建成投产的育苗室三十余处,育苗水体达15,000立方米左右。但育苗效果始终不稳定,究其原因,除了水质条件和育苗技术水平外,幼虫饵料不适也是重要的
Chlamys farreri is an important seafood economy shellfish. Clostridium dry products commonly known as “scallops”, its delicate meat, delicious, nutritious. According to the analysis, in one hundred grams of food department, containing protein 63.7%, fat 3%, carbohydrates 15%. Distributed in China in the Yellow Sea and the coast of Bohai Sea, China is an important species of development and breeding in recent years. With the development of scallop by breeding, the demand for seed is getting bigger and bigger. However, in the current sea, the natural resources are scarce and the number of artificial breeding is very small. Most of the sea area does not have the natural seedling, In recent years, the main means to solve the source of seed. Since the success of artificial seedling experiment in China in 1974, the artificial breeding of scallop has been greatly developed. At present, there are more than 30 breeding nurseries in China and about 15,000 cubic meters of nursery water. However, the effect of nursery has always been unstable, the reason, in addition to water quality and nursery skills, larval food discomfort is also important
