To cultivate Daphnia, we first need a container with a diameter of about half a meter, which contains a proper amount of water, not too deep. After that, Daphnia can be introduced. The source of Daphnia can be found in the wild, and it can be obtained and poured into containers. Proper light can accelerate reproduction, but it is necessary to avoid the increase of water temperature and replenish cold water in time. In addition, feed should be provided with a little milk or flour solution, but not too much. First, the culture container first needs a container, usually a water tank, with a diameter of about half a meter, so that there is enough space for it to breed. Of course, the bigger the water body, the better. The water quality is easy to maintain and the oxygen content is high, so it will be more convenient to raise. But the water can't be too deep, because the water pressure is too high to survive. Generally, half a meter is enough.

Second, the introduction of Daphnia will not appear out of thin air. We need to find the source of Daphnia in the wild and then introduce it into the container. It can be seen in most water bodies. As long as you look carefully and see white particles jumping around in the water, you can be sure that it is a water flea.

3. Proper illumination The growth of Daphnia cannot be separated from adequate illumination. If the environment is dark, its reproduction will be affected to some extent. Therefore, it is best to put the feeding container in a sunny place, but to avoid the water temperature rising too fast. If the water temperature is found to be too high, it needs to be mixed with cold water in time.

Fourth, providing feed Daphnia is more suitable for living in nutrient-rich water, that is to say, the nutrient content of water must be high enough to make it grow well. Usually, you can add an appropriate amount of organic matter, such as milk and flour solution, to the water. , but don't put too much, lest the water quality deteriorate and lead to a large number of Daphnia deaths.
