How to breed Daphnia without Daphnia species? How long is the breeding cycle?

The source of seeds is the key to raising Daphnia. Generally, wild Daphnia will die in large numbers after being collected, so they must be domesticated and watered before they can be raised. You can also buy domesticated seeds directly. Daphnia mainly feed on bacteria or algae. If there is no way to obtain green water, you can use yeast to raise them. While raising Daphnia, you can put a few apple snails, because a small number of adult Daphnia die every day due to old age, and apple snails can play a certain role in cleaning.

1. How to breed Daphnia without Daphnia species

1. Before breeding Daphnia, you must first obtain the seed source. Without the seed source, you cannot breed. The seed source is the key to breeding. You can collect wild seed sources, but wild seed sources must be domesticated and watered before breeding, otherwise a large number of deaths will occur. If you don't want to be too troublesome, you can directly buy domesticated seed sources. The suitable growth temperature for Daphnia is 18-25°C and the pH value is 7.5-8. No oxygen supply is required during the breeding process.

2. Daphnia pulex feeds on bacteria or algae. Green water can be used to provide food for them. If green water is not available, yeast can be used for feeding. When feeding, observe the water color first. If you can see the bottom of the container, it means that you need to feed. You can first put a small amount of dry yeast into a small paper cup, add water to dissolve it, and pour it directly into the water after it is fully dissolved. It is best to make the water a little hazy and not see the bottom.

3. When raising Daphnia, you can also put a few apple snails in the container. Because a small number of adult Daphnia die every day due to old age, even if the breeder catches a large number of Daphnia every day, it still cannot keep up with the growth and reproduction speed of Daphnia. These dead individuals will sink to the bottom and have a great impact on the water quality, and apple snails can play a certain role in cleaning.

2. How long is the reproduction cycle of Daphnia?

1. The reproduction cycle of Daphnia is generally 15-20 days. Daphnia is a crustacean. From the perspective of animal evolution, it is still a relatively low-level animal. Daphnia has a relatively simple structure and a relatively short lifespan. It is precisely because their lifespan is not particularly long that their life cycle is also relatively short and they reach adulthood earlier.

2. Generally, Daphnia can reach adulthood in about half a month of growth and development, and at the latest in about one month. After adulthood, they will have the ability to reproduce. Daphnia have a very strong reproductive capacity and a very fast reproduction speed. Generally, they can reproduce once every 2-3 days.

3. The reproduction frequency of Daphnia will be affected by the surrounding environment, such as water temperature, which is a very important factor. When the water temperature is suitable, the reproduction rate of Daphnia will be faster. When the water temperature is too low or too high, the reproduction rate of Daphnia will slow down. When the water temperature is not ideal, Daphnia will not be able to reproduce and may even die.

Which one reproduces faster, Daphnia or Shellfish?

Daphnia reproduce very quickly

Daphnia reproduce very quickly, about once every 2 to 3 days. However, this is only the reproduction speed of Daphnia when the environment is suitable. The actual reproduction speed of Daphnia is also affected by many environmental factors. Shell fleas are high in calcium and can be used as fish food, but because the reproduction speed is not as fast as that of Daphnia, and the hard shell is not particularly easy to digest, shell fleas are generally not used for large-scale breeding.

Shell fleas may affect the molting of shrimps and are not suitable for feeding shrimps. The breeding conditions are exactly the same as those for Daphnia. The temperature is maintained at 15℃ to 25℃, and sufficient nutrients and oxygen are ensured in the water. Daphnia reproduces quickly in water temperatures of 20 degrees Celsius, mainly through parthenogenesis.
