Preparation of containers: crabs can be raised, want to raise crabs, first of all, prepare a water basin, the bottom of a layer of sand. Adjust the water quality: you can choose clean river water or lake water for breeding, and change the water once every 7 days. Regulate water temperature: Keep the water temperature at 15 degrees, which can promote the digestion of crabs. Feed feeding: daily feeding is based on meat.
How to raise crabs
1, prepare containers
Raise crabs first to prepare a container, the container can be used in a water basin, can effectively avoid the water is too deep, is not conducive to the cultivation of crabs, the conditions of the tank can be chosen to tank wall higher tanks, to prevent the escape of the crabs, and then in the bottom of the container to lay a layer of sand, appropriate planting a few plants water plants.
2, regulate the water quality
Breeding water can choose clean river or lake water, you can also use tap water, but to dry before use, tap water contains chlorine, there is a certain degree of harm to aquatic animals, an average of every 7 days to change the water, if it is the cultivation of sea crabs, you also need to go to configure a special salt water.
3, adjust the water temperature
The water temperature has a great impact on the growth of crabs and health, usually the water temperature is maintained at 15 degrees is most suitable to promote the digestion of crabs, the water temperature of 10 degrees or less, the crabs will be because of the low temperature, the activity sharply reduced, the intake of food will also be reduced.
4, feed feeding
Crabs are omnivores, daily feeding to meat-based, plant-based feeds, meat can feed some small fish, shrimp, eggs, red nematodes, etc., plant-based feeds to choose pumpkin, corn, potatoes boiled for feeding, each time do not feed too much, eat the rest of the food scraps should be fished out in time to avoid contamination of the water. Avoid polluting the water.
