夏季是观赏鱼生长发育的旺季,对金鱼、热带鱼和锦鲤来说都是如此。但当气温高达37℃-38℃时,水温亦常高达30℃以上,此时要特别警惕缺氧和“烫尾”两大威胁。要做好防暑降温工作,主要措施是加深水位至35cm-40cm,观赏鱼可潜入温度较低的深层,尽量设法使水温控制在30℃以内。彻底清污、勤换水和遮盖遮光网或苇帘,可减慢水温升高,保持水中较高的溶氧量和抑制浮游植物的大量繁殖,是预防观赏鱼“浮头”和“烫尾”的有
Summer is the season for ornamental fish growth and development, both for goldfish, tropical fish and Koi. But when the temperature is as high as 37 ℃ -38 ℃, the water temperature is often as high as 30 ℃ above, this time to be particularly vigilant hypoxia and “hot tail” two threats. To do a good job of sunstroke cooling, the main measure is to deepen the water level to 35cm-40cm, ornamental fish can penetrate into the lower temperature, try to try to make the water temperature controlled within 30 ℃. Thoroughly decontamination, frequently changing the water and covering the shade net or reed curtain can slow down the water temperature, keep the high dissolved oxygen content in the water and inhibit the large multiplication of the phytoplankton, and prevent “floating head” and “hot tail” There
