The bait method is a common method for preventing and treating crab disease. This method has a good effect on parasite and bacterial infections and health care in crabs. The following points should be noted when adopting the bait method to prevent crab disease.
The principle of drug selection. There are many functions of crab medicine, and the main role is three aspects: that is, to suppress and kill pathogens, improve the breeding environment, and enhance the crab's own resistance. For the function of inhibiting and killing pathogens, the side effects of drugs on crabs can not be ignored, there may be cross-resistance between drugs and drug multiplication, addition and phase effect.
Ensure that the diseased crab eats enough medicine. One is that the stability of the bait in the water is better. The choice of bait must be for crabs to eat and palatable and use adhesives.
The medicine baits do not spread quickly after entering the water, and the diseased crab can eat enough medicine. Second, the amount of medicine to be fed should be accurate. Calculate the amount of medicine according to the body weight of crabs, and consider other food-feeding baits (such as fish and shrimp in mixed ponds). Try to reduce waste. You can use fish and shrimp first. Feed, then feed baits. The third is that the bait must be fed for one course of treatment (usually 3 to 7 days or 7 days) or after the crab stops dying, continue feeding for 1 to 2 days. If the drug is stopped prematurely, the pathogenic bacteria in the body of the crab will recur.
Pay attention to the feeding method of the bait. Before the feeding of baits, one insecticide should be used to kill the surface parasites of the crabs and the water quality should be adjusted to ensure that the water quality is good and the dissolved oxygen is sufficient. The crabs are fed one day of bait, and the baits are given the next day. The bait is mainly fed in the evening, which increases the chance of feeding the bait for sick crabs and weak crabs, and can make a bait once in the morning of the next morning. Do not change the water or replenish the pool water during the feeding process to avoid aggravating the crab disease or causing recurrence. After the bait is fed, a water quality adjustment is performed.
