What are the technical points of shrimp farming in rural areas?

Point 1: temperature crayfish can't adapt to the growth in high or low temperature environment, so the growth temperature should be controlled in the range of 15-35 degrees, and the most suitable temperature is about 20-25 degrees. If it exceeds 15-35 degrees, the growth of crayfish will be affected, the appetite will decrease, the growth rate will slow down, or even stop growing.

The second point: density cultural density is very important. Once the amount of culture is too much, it will affect the growth of crayfish and increase the incidence of crayfish. In addition, the intensive culture is not easy to manage, and it is prone to hypoxia, which increases the mortality rate of crayfish. Only by ensuring a reasonable breeding density can the healthy growth of crayfish be guaranteed.

Point 3: Nutrition is a common problem of many farmers, and there is no correct feeding and selection of crayfish feed. Crayfish not only eat meat, but also can be mixed with a little forage. Some vegetables or aquatic plants can be properly planted around the pond, and then fed reasonably with various carnivorous feeds. Now many farmers will mix myna into feed, which can not only effectively improve intestinal health and enhance intestinal immunity; It can also protect the liver and gallbladder and promote digestion and absorption. In addition, Sterling has played an active role in attracting food and promoting growth.

The fourth point: water quality is an aspect that is easily overlooked by everyone. Although crayfish can live in poor water quality environment, it is also easy to produce many parasites, which will cause harm to people after eating. Therefore, the water quality of crayfish should be controlled at a clean and fresh level. Clean water can promote the growth of crayfish and improve their meat quality. Youjiling is widely used by farmers in Jiangsu and Zhejiang provinces, which can inhibit the production of toxic substances such as ammonia nitrogen and nitrite, increase dissolved oxygen in water and repair bad water bodies. Its rich nutrients such as small peptides can also promote the growth of beneficial algae in water and cultivate natural bait; In addition, Youjiling can also reduce the stress response caused by external environmental changes and protect aquatic animals.

Fifth point: Disease prevention Although crayfish has strong adaptability, many diseases will occur if it is not well managed, such as rotten shell disease and soft shell disease. Diseases are very unfavorable to the growth of crayfish, so we must pay attention to the prevention of diseases in the process of crayfish culture. Strengthen the management of ponds, do a good job in water quality treatment, and upgrade their own aquaculture technology in order to cope with various situations in time.

With the cold weather, crayfish culture has entered the late growth stage. During this period, we should feed more feed and use excellent aquatic products for a long time to strengthen our physique and prepare for the coming winter. Improving the survival rate in winter is the key to a bumper harvest in the coming year.
