海洋是人类的食物仓库,它蕴藏的丰富的渔业资源,是人类必需的几种氨基酸的重要来源,为人类提供了大量的营养食物。要使这些资源得到发展,能够满足人们越来越多的需要,必须将渔业生产的重点转移到海水养殖上,并尽可能地采取新技术措施提高水体的负荷能力,也就是提高海水养殖的单位面积产量。海水养殖一般是在沿岸浅水区、内海、内湾、滩涂及营建的虾池等范围内进行的。这些水域内立体放养的潜力是很大的。要发展海水养殖就要提高海水养殖的集约化水平,改变粗放管理,单一种群平面养殖的方法,利用不同鱼、虾、贝、藻的习性,在海水这个广阔的空间里,实行立体养殖。实践证明这是一条最有效的途径。实现立体养殖可用下列形式和技术。
The ocean is a human food warehouse. Its rich fishery resources are an important source of several kinds of amino acids necessary for human beings and provide a large quantity of nutritious food to human beings. If these resources are to be developed to meet the increasing needs of the people, the focus of fishery production must be shifted to mariculture and new technological measures should be taken to increase the load capacity of water bodies as much as possible, that is, to raise the unit for mariculture Area production. Marine aquaculture is generally carried out in shallow water areas along the coast, inland sea, inner bay, shoals and shrimp ponds. The potential for stereo stocking in these waters is significant. In order to develop mariculture, it is necessary to increase the intensity of mariculture, change the method of extensive management and single-population planktonization, and utilize the habit of different fish, shrimp, shellfish and algae to practice three-dimensional breeding in this vast space of seawater. Practice has proved that this is the most effective way. To achieve the three-dimensional culture available the following forms and techniques.
