南方的鱼塘，在高温季节常暴发蓝藻(方言叫湖淀，也称铜锈水)，对养殖鱼类是有害的。要杀灭这种蓝藻，用0.7毫克/升硫酸铜全池泼洒很有效，但对养殖散鳞镜鲤和兴国红鲤的亲鱼塘，使用时要非常注意，至少在我们当地，这两种亲鱼对硫酸铜较敏感。我处主养散鳞镜鲤和兴国红鲤鱼塘 Southern fish ponds, often in the hot season of cyanobacteria outbreak (dialect called Lake, also known as copper rust water), is farmed fish is harmful. To kill this cyanobacteria, with 0.7 mg / l copper sulfate Quanchiposa is very effective, but the breeding of Sclater mirror carp and Xingguo red carp of the parent fish ponds, be very careful when used, at least in our local, these two Broodstock are more sensitive to copper sulfate. I advocate scattered Scattered mirror carp and Xingguo carp pond
