从七十年代以来,世界各沿海国家普遍采取了渔业保护措施——纷纷宣布200海里专属经济区,使发达国家的远洋渔业受到了一定的限制。为了适应这种新形势,水产增养殖事业已为各国所重视,有些国家把养殖生产做为一项战略措施来抓,所以近年来发展很快。一、发展海水增养殖事业是渔业发展的必然趋势 (一) 为了满足世界人口不断增长的需要,联合国粮农组织(FAO)把鱼类、肉类、豆类列为三大蛋白供应源,提倡加强研究和利用。可是依赖畜牧业和农业提供的肉类和豆类都是陆地产品,受到土地和其他因素的限制,因此,人们很自然地把注意力转向尚未充分开发的辽阔海洋,希望从海洋中获取大量价廉、味美的动物蛋白。但是,蕴藏在海洋中丰富的自然 Since the 1970s, fishery protection measures have been universally adopted by all the coastal countries in the world. They all announced the exclusive economic zone of 200 nautical miles, which restricted the developed countries’ offshore fishing industry. In order to adapt to this new situation, aquaculture and aquaculture has been valued by all countries. In some countries, aquaculture and production have been taken as a strategic measure so that it has developed rapidly in recent years. I. Development of seawater aquaculture is an inevitable trend in the development of fisheries 1. In order to meet the growing needs of the world’s population, the United Nations Food and Agriculture Organization (FAO) has classified the three major sources of fish, meat and beans as sources of supply and advocated strengthening Research and utilization. However, meat and beans, which depend on livestock husbandry and agriculture, are land-based products that are limited by land and other factors and, as a result, it is natural for people to turn their attention to the underdeveloped and vast oceans in the hope of obtaining large amounts of value from the oceans Cheap, delicious animal protein. However, rich in the nature of the ocean
