The development of a fat hairy crab.
Hairy crab is a traditional Chinese delicacy, which is delicious and nutritious, and is deeply loved by people. And a plump hairy crab is even more mouth-watering. So, how do you raise a plump hairy crab? Let's take a look at it.
First, the breeding environment.
The breeding environment of hairy crabs is very important, and it is necessary to choose a place with clear water quality, quiet environment and abundant aquatic plants. The freshness of the water is conducive to the growth of hairy crabs, and aquatic plants are the main food of hairy crabs**. At the same time, the breeding environment should avoid pollution and noise interference, and keep it quiet and natural.
Second, the construction of breeding ponds.
The breeding pond is the place where hairy crabs grow and inhabit, and the living habits and growth needs of hairy crabs should be considered when building. The pond should be divided into shallow and deep waters, with shallow water being conducive to hairy crabs crawling and feeding, and deep water providing shelter and rest. In addition, the breeding pond should also be equipped with anti-escape facilities to prevent hairy crabs from escaping.
3. Feed selection and feeding.
Hairy crabs are omnivorous animals and need to eat a variety of feeds to ensure a balanced nutrition. Natural bait such as fish, shrimp, shellfish, and algae can be used as feed, or it can be fed with feed. When feeding, an appropriate amount should be put according to the growth stage and food intake of hairy crabs to avoid excessive or insufficient. At the same time, it is necessary to ensure the freshness and quality of the feed to avoid affecting the growth of hairy crabs.
4. Water quality management.
The quality of water quality directly affects the growth and health of hairy crabs, so water quality management is very important. Water quality indicators should be regularly tested, including pH value, dissolved oxygen content, ammonia nitrogen, etc., and adjusted according to the actual situation. At the same time, it is necessary to change the water regularly to keep the water quality fresh and stable. In the high temperature season, measures such as increasing oxygen and cooling can be taken to reduce the mortality rate of hairy crabs.
5. Disease prevention and control.
Hairy crabs are susceptible to various diseases during their growth, so disease prevention and control is also an important task in the breeding process. Hairy crabs should be inspected regularly, and abnormal situations should be dealt with in a timely manner. At the same time, it is necessary to use drugs rationally to avoid drug residues and harm to hairy crabs. When using drugs, it is necessary to strictly follow the instructions for use of drugs to avoid unnecessary losses.
6. Fishing and Marketing.
When hairy crabs reach a certain size and quantity, they can be caught and sold. Appropriate tools and methods should be used when fishing to avoid harm to hairy crabs. When selling, you can choose the appropriate sales channels and methods according to market demand and the best situation. In the sales process, it is necessary to ensure the freshness and quality of hairy crabs and improve consumer satisfaction.
In short, raising a plump hairy crab requires comprehensive consideration of many factors such as breeding environment, breeding pond construction, feed selection and feeding, water quality management, disease prevention and control, and fishing and sales. Only when these aspects are fully prepared and managed can high-quality hairy crabs be bred to meet the needs of consumers. At the same time, it is also necessary to pay attention to the protection and sustainable development of the ecological environment to achieve the dual goals of economic and social benefits.
