CATDOLL : CATDOLL: How to breed hairy crabs?

The hairy crab is a traditional delicacy in my country, with high drinking value, efficacy and economic value. The hairy crab is oviparous and generally reaches sexual maturity in 2 years. It begins to breed and migrate in autumn every year, mates and lays eggs in brackish water, and hatches and grows. Its life span is divided into three stages: larval stage, yellow crab stage, and green crab stage. It is loved by everyone and is relatively expensive. So, how to breed hairy crabs?

First, whether it is to cultivate crab seeds or to raise adult crabs, the first thing to do is to select the right seedlings, which is also the key to successful breeding. There are two types of crab seedlings: artificial breeding and natural capture. Naturally captured crab seedlings have a more complicated origin, more water imports, and are expensive, and there are too many uncertain factors. A major advantage of artificially breeding crab seedlings is that the size of its parents can be strictly controlled, which ensures the authenticity and survival rate of the bred crab seedlings, and the price is only about half of that of natural crab seedlings. Taking all factors into consideration, it is more cost-effective to use artificial crab seedlings.

Second, use high-quality complete pellet feed for hairy crabs. Compared with traditional feeding methods such as wheat and corn, the use of high-quality complete pellet feed has the following advantages: 1. Convenient feeding. 2. Strong palatability and not easy to pollute the water body. 3. Obvious economic benefits of breeding. If it is really difficult to buy complete pellet feed for hairy crabs, we can prepare feed by ourselves, but we must add mud shovel molting agent.

3. Strengthen feeding management.

1. Effective feeding amount and feeding time. The feeding amount is different at different growth stages. The daily feeding amount should be adjusted according to the temperature of the day and the feeding status of the previous day. The feed should be placed on the steep slope close to the water level or in the shallow water area beside the pond. The feeding time can be chosen in the evening every day.

2. Do a good job of regulating and adjusting the water environment. Use quicklime powder to adjust the water body frequently to keep the water fresh. The water level of the crab pond should be maintained at 0.6-1 meter in spring and can be deepened to 1-1.5 meters in summer. When changing water, the water level difference between the inside and outside should not be too high. It is best to maintain a long-term micro-flow.

3. Carry out pond inspections. Once problems are found, effective measures must be taken immediately.

During the breeding process, you should also pay attention to hygiene and water quality. It is best to feed the crabs by feeding, which may be more appropriate. You also need to do a good job of management during breeding. You must check carefully every day and observe the growth process of the hairy crabs. These processes are very important.

You should choose better seedlings, and when breeding, you must follow the corresponding size. You should also pay attention to choosing some good particles. You must pay attention to water issues and strengthen management.

In general, we should pay attention to water quality, choose a suitable place for breeding, and be sure to choose the right species. When humans breed, we must pay attention to the selection of crab seedlings and follow scientific methods.

First of all, you should choose good seedlings and provide very good water quality. Then you should strengthen feeding management, make corresponding adjustments to the water environment, learn scientific breeding techniques, and also pay attention to mating issues and control temperature issues.
