【摘要】：为了解我国海水养殖业的自身污染状况,本文利用2014年全国海水养殖产量及主要养殖生物产污系数等数据对我国海水养殖活动氮、磷的产出量进行了初步评估。结果显示,全国海水增养殖区氮、磷年产出量分别达到29.3万t和9.7万t。其中,投饵性养殖生物(鱼类、甲壳类等)总氮、总磷产出量分别达到3.9万t和0.6万t,非投饵性养殖生物(滤食性贝类)总氮、总磷产出量分别达到25.4万t和9.1万t。与全国陆源污染物排海量相比,海水养殖总氮、总磷产出量分别约占江河总氮、总磷排海量的10.0%和36.1%;同时,海水养殖总氮、总磷产出量已分别超过排污口氨氮、总磷的排海量,分别约为二者的5.6倍和7.2倍。因此,海水养殖自身污染已成为我国近岸海域重要污染源之一,应引起相关部门的足够重视。
[Abstract]:In order to understand the self pollution status of the marine aquaculture industry in China, the output of nitrogen and phosphorus in the marine aquaculture activities in China was preliminarily evaluated by using the data of the national mariculture production and the main biological pollution factor in 2014. The results showed that the annual output of nitrogen and phosphorus in the national aquaculture area reached 293 thousand T and 97 thousand T., respectively. Total nitrogen of bait breeding organisms (fish, crustaceans, etc.), the total phosphorus output of total phosphorus reached 39 thousand T and 6 thousand T respectively, the total nitrogen of non bait breeding organisms (Filter Feeding Shellfish), total phosphorus output reached 254 thousand T and 91 thousand T., compared with the national land source pollutants. At the same time, the total amount of total nitrogen and total phosphorus in mariculture have exceeded the emission of ammonia and nitrogen, and the amount of total phosphorus is about 5.6 times and 7.2 times of the two, respectively. Therefore, the pollution of mariculture has become one of the important sources of pollution in the coastal waters of China, which should be paid enough attention by the related departments.
