实践证明,利用滩涂建池培育贝苗是解决种苗不足的好途径。贝类人工育苗打破了自然海况环境的制约,技术简便、易行。我国海域辽阔,贝类资源极为丰富,经济价值较大的就有150多种,现在已经开发利用的主要是一些生活在潮间带或水深不超过一二十米处的贝类。目前世界上已养殖(包括增殖品种)的贝类约有60多种,我国目前养殖的或正在开展试验将要增加养殖的有30多种。养殖的品种大都为腹足类,属埋栖型,即主要在泥沙中生活的种类。食性多是属于滤食性。
Practice has proved that the use of beach ponds to cultivate shellfish seedlings is a good way to solve the shortage of seedlings. Artificial breeding of shellfish broke the constraints of the natural sea environment, the technology is simple and easy. China has a vast sea area and abundant shellfish resources. There are over 150 species of great economic value. The main species now under development and utilization are those that live in intertidal zones or water depths of not more than 10-20 meters. At present, there are more than 60 species of shellfish that have been cultured (including multiplication varieties) in the world. There are over 30 species of aquaculture species currently under cultivation or under development in China. Breeding species mostly gastropods, is a buried habitat, that is, mainly in the types of sediment life. Diet is more than filter feeding.
