随着生活污水和工业废水的日益增多,自然环境的破坏和恶化和养殖自身污染加剧,养殖水环境日益严重污染,各种病原生物不断增多,不断变异更新,养殖疾病频发,导致水产养殖蒙受了巨大经济损失,严重威胁着水产养殖业的健康发展,养殖污染物的排放、沉积可引起水体富营养化,但目前仍缺少控制和解决的有效措施。为此,必须加强池塘养殖中有机污染的控制和防范。
With the increasing domestic sewage and industrial waste water, the destruction and worsening of natural environment and aggravation of pollution in aquaculture, the increasingly serious pollution of aquaculture water environment, the continuous increase of various pathogens, the constant mutation and update, frequent occurrence of aquaculture diseases A huge economic loss, a serious threat to the healthy development of aquaculture, aquaculture emissions of pollutants, sedimentation can cause eutrophication of water bodies, but there is still no effective control and solution. To this end, we must strengthen the control and prevention of organic pollution in pond culture.
