1, water quality: brocade carp do not like hard water, so before raising, need to soften the water, otherwise the fry is difficult to adapt. If tap water is used for aquaculture, it is necessary to put tap water in the sun in advance for drying, so that the water releases chlorine, which is convenient for aquaculture.
2. Water temperature: Two to three centimeters of koi seedlings do not require high water temperature, keep the water temperature at 25 degrees Celsius. If the water temperature exceeds 27 degrees Celsius, oxygen should be started to avoid hypoxia of Koi seedlings.
3. Feeding: Two to three centimeters of Koi carp seedlings are in a period of vigorous growth, and their demand for nutrients is relatively high. In addition to general fish feed, they also need to be fed with animal feed, such as earthworms and red worms, to promote the growth of Koi carp seedlings. In general, feeding animal feed twice a week can meet their needs.
When raising two to three centimeters of brocade carp fry, keep the water temperature between 20 and 26 degrees Celsius. They do not require high water, and can be cultured with ordinary tap water. They do not have high requirements for food, and general fish feed can be fed. Koi seedlings are in the growth period, the consumption of oxygen is relatively large. If the breeding density is relatively large, oxygen is needed. But if the density is not large, oxygen can not be used.
