Hairy crabs are a kind of food that many people like to eat. Although the price of hairy crabs is currently a bit expensive in the market, its demand is still very large. Affected by the market environment, many people have begun to invest in hairy crabs. Is it risky to raise hairy crabs? Affordable hairy crab breeding technology and methods!
1. Is the risk of hairy crabs?
1. The risk of hairy crabs is related to the quality of management technology. In order to reduce the risk of breeding, you need to choose high -quality crab seedlings. Put the crab in the pond. The crab’s ability to adapt to water quality is put in when there is no adverse reaction.
2. In order to ensure good breathability, the sand or soil land should be mainly controlled at about 1m. The shallow place cannot be less than 10cm, leaving several mounds in the pond, planting reeds, white white white white white, white white white white white, white white white white white, white white white white white white, white white white white white, white white white white white, white white white white white, white white white white white white white white white white white white white white white white white white white white white white and white white white Aquatic plants such as 菖, provide a good living environment for crabs.
3. It is forbidden to feed metamorphic feed, mainly to put meat feed, with some nutrients, especially plant feed to ensure good water quality of the pond. The number of feeding needs to be determined according to the change of temperature.
Second, hairy crab breeding technology and method
1. Crab species selection
The choice of crab seedlings is actually relatively simple. Usually we choose more uniform color, normal size and normal limbs, no disease, and no activity damage to active big yellow crabs. The survival rate will be higher, and the growth rate and reproduction ability will be stronger.
2. Scientific reservation
Before releasing, we need to disinfect the crab seedlings to prevent the quality of pollution and affect the healthy growth of other crab seedlings. Secondly, the depth of the water at the time of the first placement is between 1:5 meters and 2 meters. The water temperature of the farm is basically about twenty to 25 degrees Celsius. After one month, they slowly adapt to restoration to normal temperature. Finally, under the conditions of the growth conditions, about 300 hairy crabs are usually stored per acre, so that their activity space and food will be more sufficient.
3. Breeding management
The peak season of hairy crabs is usually in summer. At this time, we need to seize better opportunities. We will provide more nutrients for hairy crabs to promote rapid growth, usually based on plant private chat. For example, wheat, corn, pumpkin, etc., when it is autumn, it is generally the stage of fattening of hairy crabs, so we need to add snails, snails, small fish, and river mussels to make crabs eat well, can use crabs to make use more money.
4. Daily management
We must continue to observe the water quality of the farm. Good water quality is a relatively important factor in the growth of hairy crabs. In spring and autumn, it usually needs to be replaced every half a month. The temperature in summer is relatively high, so basically you need to replace the water once a week, and the temperature will fall for about one month before changing the water. The second is to check the anti -escape system to prevent crabs from escaping. Finally, it is necessary to disinfect the farm from time to time to avoid affecting the growth of hairy crabs.
5. The prevention and control of pests
During the breeding process, hairy crabs often encounter crab parasites and water mouse damage, etc. We can use lime, omotycin erythromycin, chitin or chitin, formalin, copper sulfate and mouse cage, mouse, mouse, mouse, mouse, mouse Cycles are used to prevent and treat.
In summary, raising hairy crabs has certain risks, but the risks are affected by many factors, but in general, the breeding prospects of hairy crabs are still good.
