非净化的污水,对渔业水域应该大大地限制排放,甚至完全禁止利用。污水和其他的污染可以影响到:1)水域的物理一化学和生物性质;2)水域饵料资源;3)鱼类的贮存和4)渔场。从渔业的观点上来看,污染和污水它们对水域的影响可分为三个方面:1)在自己的分解过程中所形成的有毒物质的污染及水的物理——化学性质和在分解过程中它的气体状况所引起的对鱼有害的污染;2)自身毒物的污染;3)除了自身毒物的污染外,在水体经受变化的过程中,结合水中溶解的游离的氧甚至还形成新的有毒的物质。
Non-purified sewage should greatly limit emissions to fishery waters or even ban them completely. Sewage and other contaminants can affect: 1) the physical-chemical and biological properties of the waters; 2) the water resources of the fish; 3) the storage of fish and 4) fisheries. From a fisheries point of view, pollution and sewage impacts on waters can be divided into three areas: 1) pollution of toxic substances formed during their decomposition and the physico-chemical properties of water and its decomposition during the process Its pollution to the fish caused by its gaseous conditions; 2) pollution of its own poison; 3) in addition to the pollution of its own poisons, the formation of new toxic Material.
