为了更好地利用海洋资源,在同一海区内进行不同形式的多品种增养殖,不但能充分利用海区资源,维护海区生态的良性循环,而且,能够相互促进提高经济效益。 1.海区概况长岛县四面环海,浅海水域广阔,海产生物资源丰富,30米等深线以内的宜增养殖水面约达23万亩(1亩=0.0667公顷),随着增养殖技术的不断提高,向40米以外的深水海区发展,潜力更大。浅海海底可增养殖面积也很大,岩礁,砾石是理想的增养殖基础,40米水深以内的有3万多亩,5～20米水
In order to make better use of marine resources, different forms of multi-species aquaculture within the same sea area will not only make full use of marine resources and maintain a virtuous circle of marine ecology, but also promote economic benefits. 1. Overview of the sea area Long Island County, surrounded by the sea, the vast shallow waters, rich seafood resources, within 30 meters isobath line should be increased by about 230,000 acres of aquaculture water surface (1 mu = 0.0667 hectares), with the continuous breeding technology Increase, 40 meters away to the deep-water sea development, greater potential. Shallow sea bottom aquaculture can increase the area is also very large, rock reefs, gravel is the ideal basis for aquaculture, 40 meters deep within 30,000 acres, 5 to 20 meters of water
