夏秋季节,气温较高,若池塘中有机质较多,这时候蓝藻常常会大量繁殖,形成水华,又称“铜锈水”、“湖淀”。这种水质条件下,鱼类易缺氧浮头,甚至致病死亡。因此,调节好水质,控制蓝藻的过度繁殖对提高鱼池产量、预防鱼病有着重要意义。 Summer and autumn, the temperature is high, if the pond organic matter more, this time the blue algae often multiply, forming the bloom, also known as “copper rust water”, “lake”. Under such water quality conditions, fish are vulnerable to hypoxia and even death from disease. Therefore, regulating the water quality and controlling the over-breeding of cyanobacteria is of great significance for raising the yield of fish ponds and preventing fish diseases.
