It is necessary to pay attention to the water quality and water temperature when raising swordfish. The water quality should be weak acid or weak alkaline, and the PH value should be 7.2 ~ 7.4, and the water temperature should be 25 ~ 28 degrees. At the same time, use natural water or treated tap water, and keep changing water regularly. During the feeding period, it is necessary to feed a small number of times to ensure that a variety of foods are fed to prevent malnutrition.

Matters needing attention in raising swordfish

Water temperature and water quality are important conditions for raising swordfish. During the feeding period, it is necessary to adjust the water quality to weak acid or weak alkaline water quality, with a PH value of 7.2 ~ 7.4, and control the water temperature at 22 ~ 25 degrees, preferably not lower than 20 degrees, to avoid affecting the appetite of swordfish.

It is best to use natural water, such as well water, river water, etc. If tap water is used, it needs to be exposed to the sun in advance. When changing water, it is necessary to ensure that the water is changed every three days, and only one third of the water can be changed at a time.

In order to ensure the reasonable and healthy diet of swordfish, it is necessary to ensure diversification in usual feeding, and to feed a small number of times. Small fish are fed three or four times a day, and adult fish are fed once or twice a day, mainly with fish feed and live feed.
