现代高密度集约化的水产养殖模式,往往会因为投入过量饵料而导致高蛋白质残饵和高含氮排泄物不断沉积于池底,并被水中的微生物分解成含氮物,导致养殖水体中氨氮、亚硝酸盐等有害物质积累,出现水体和底质富营养化,引起养殖水域生态环境恶化,影响养殖生物的正常生长甚至导致其死亡。养殖水体中亚硝酸盐的产生、危害以及怎样预防和消除亚硝酸盐,本文拟从生 Modern high-density intensive aquaculture models often result in the deposition of high-protein bait and high-nitrogen-containing excrement on the bottom of the pond due to excessive feed intake, decomposition by microorganisms in the water into nitrogenous matter, and ammonia nitrogen in aquaculture water , Nitrite and other harmful substances, the emergence of water and sediment eutrophication, aquaculture caused by the deterioration of the ecological environment, affecting the normal growth of aquaculture organisms and even led to its death. Aquaculture water nitrite, hazards and how to prevent and eliminate nitrite, this paper intended to students
