发展滩涂贝类养殖业,应根据各种贝类的生殖特点,结合本地区的自然条件,修建贝类育苗池。在滨海滩涂上修建育苗池,要注意以下问题。一、育苗池场地的选择贝类育苗池要从投资少、生产安全、有发展前途等方面慎重考虑,一般需注意以下几点: 1.位置:应选择滩地平坦、风浪较小、易于排灌,无工业污染、位置高底适中的内海滩涂。 2.底质:根据养殖贝类品种选择适宜的底质,或先进行底质的改造再建池。 3.水质:建育苗池附近的海区水质要适于贝类发育生长。海水的比重一般在1.010～1.025之间;pH值
The development of beach shellfish breeding industry should be based on the reproductive characteristics of various shellfish, combined with the natural conditions in the region, the construction of shellfish nursery ponds. In the coastal beach painted nursery pond construction, pay attention to the following questions. First, the choice of nursery ponds shellfish nursery ponds from less investment, production safety, there are prospects for development and other aspects of careful consideration, generally need to note the following: 1. Location: Beach should be flat, less stormy, easy irrigation and drainage, No industrial pollution, the location of high end of the beach within the coating. 2. Sediment: According to breeding shellfish species to choose the right sediment, or the first sediment reconstruction and then build the pool. 3. Water Quality: Sea water near the nursery ponds should be suitable for the growth and development of shellfish. The proportion of sea water is generally between 1.010 ~ 1.025; pH value
