Control button for crab seedlings

1, crab ponds to simulate the natural ecological environment, plant some aquatic plants in the seedling pool, and put aquatic peanuts and other plants, the area can be one-third of the water body, aquatic plants not only for feeding crabs, hidden attachment shelling , Cooling, and aquatic grasses can breed many aquatic animals, can increase the natural bait of crab seedlings, while water plants can also absorb fertilizer, play a role in water purification.
2, to keep the crab dung to grasp the method of feeding, large-eyed larvae when the pond, the water to be fat, to cultivate appropriate amount of plankton, feeding to do two fine, middle green. That is to say, pre- and post-feeding should be refined, and medium-term should be young. Specifically, in the 4th to 5th phase of juvenile crabs, concentrates should be concentrated, and some fine fish and pelleted foods should be fed, and they should be served for 7, 8 and 9 months. , to feed less concentrate, more suitable for feeding pajamas, such as calf Sha best, when the weather is hot, crabs like to eat cold food.

3, do a good job of injection and drainage work, continuously improve the water quality, raise the water level, increase dissolved oxygen, and control the fatness.
4, to adjust the PH value of the pool water, the best PH value of the growth of crab seed in the 7.5 to 8.5, to maintain this standard, must be applied twice a month lime, usually 15 kg per acre, this can adjust the water quality It can also prevent seed diseases.
5, pond culture and crab should be moderate, the area should not be too large or too small, generally about 2 acres is appropriate, culture crab pond mode, the best dish type, should not set the crab island, pool slope should not be steep, The slope ratio of 3:4 is appropriate and the water depth is about 1.5 meters.
