我县的对虾养殖业发展势头自80年代初出现了第一个高峰期,养虾面积由几百亩迅猛发展到6万多亩,产量、效益等均曾创全国五项指标第一。仅十年来,特别是1993年以来,对虾养殖业遇到了前所未有的灾变,由于受近海港湾、河口水域富营养化的影响,对虾生态环境受到严重破坏,虾病长期难以根治,使我县对虾养殖业步入困境,多年徘徊不前。 The development of prawn aquaculture industry in our county has shown its first peak since the early 1980s. The area of ​​shrimp aquaculture has rapidly developed from several hundred mu to more than 60,000 mu. Output, benefits, etc. have hit the top of the five indicators in the country. In the past ten years alone, especially since 1993, the shrimp aquaculture industry experienced unprecedented catastrophe. Due to the eutrophication of offshore harbor and estuarine waters, the ecological environment of shrimp was severely damaged and the shrimp disease was hard to cure for a long time. Industry into trouble, many years stagnant.
