金鱼饲养条件下的含氧量

金鱼饲养条件下的含氧量

金鱼（详细信息）

金鱼水中的含氧量是判断水质的标准。氧气是金鱼非常重要的生存条件。当空气中的氧气与水接触或水中的植物在光合作用期间产生氧气时，水中的氧气溶解在水中。那么，当饲养金鱼时，水中的适当氧含量是多少？

天然水中的溶解氧含量相对较高。天然水是指河流、湖泊和海洋，可达到8-12 mg/L。然而，在人工饲养条件下，鱼塘和鱼缸的开口面较小，照度受到一定程度的限制，饲养密度相对较高，因此需要安装气泵充气以增加溶解氧。如果养鱼密度小，曝气器每天可以运行8小时左右。如果密度高，应该保持24小时

除了氧气，还有一个条件：光照，这对水质的转化和水草的生长有重要意义。阳光中的紫外线也有杀菌作用。因此，可以利用光线来补充缺乏光线的室内水箱，并且可以安装紫外线灯，每天照射几个小时，以补充阳光的不足

Oxygen content in goldfish feeding conditions

Goldfish (details)

The oxygen content in goldfish water is a standard to judge the quality of water. Oxygen is a very important living condition for goldfish. The oxygen in water is dissolved in water when the oxygen in the air is in contact with water or the plants in the water produce oxygen during photosynthesis. So what is the proper oxygen content in the water when raising goldfish

The amount of dissolved oxygen in natural water is relatively high. Natural water refers to rivers, lakes and seas, which can reach 8-12 mg/L. However, under artificial feeding conditions, the opening surface of fish ponds and fish tanks is small, the illumination is limited to a certain extent, and the feeding density is relatively high, so it is necessary to install an air pump to inflate to increase dissolved oxygen. If the density of fish farming is small, the aerator can be operated for about 8 hours every day. If the density is high, it should be kept on for 24 hours

In addition to oxygen, there is another condition: light, which is of great significance to the transformation of water quality and the growth of water plants. Ultraviolet rays in the sun also have bactericidal effect. Therefore, light can be used to supplement the indoor water tank that lacks light, and the ultraviolet lamp can be installed to illuminate for several hours every day to supplement the lack of sunlight
