1. Pond and density: When red worms are cultured artificially, the number is generally large, and large-scale culture is very common. The first thing to pay attention to is the culture pond and density. Red worms can be cultured in cement ponds, the water depth can be controlled at 20-30 cm, not too deep, and some sludge can be put at the bottom of the ponds. The number of red worms should not be too large, otherwise there will be insufficient dissolved oxygen in the water and insufficient food.

2, food: red worms can eat more food, some red worms only eat meat, while others are omnivorous, both meat and vegetarian can be eaten, and even some bacteria can become their food. If the red worm is cultured artificially, you can also add some glucose to the water, so that the growth and development of the red worm will be better.

3. Water temperature: Pay special attention to the water temperature when breeding red worms, because the water temperature has a great influence on the growth and development of red worms. Red worms are not afraid of heat and cold, which can be kept at about 10 degrees, that is, more than ten degrees. When the temperature is suitable, the growth and reproduction speed of red worm is faster.

4, change water: breeding red worms must pay attention to change water, otherwise the water quality is poor and the dissolved oxygen is insufficient. The specific water changing frequency can be determined according to the state of water in the pool, and the water quality in the pool can be monitored in real time.

5, lighting: red worms don't like strong light, so try to keep the pool dark. If there is strong light during the day, it is recommended to cover it in time.
