Have you ever learned about the three small inventions in river crab farming?

River crab is a common crab in life, also known as the rich freshwater products, the artificial breeding technology of river crab has become the leading industry and pillar industry in China's freshwater breeding, river crab breeding after years of development, in the use of production and operation tools, there are a lot of inventions in the folk, the principle is simple, the use is convenient, greatly improve the production efficiency. Let's introduce these three inventions.

1.Drug sprayers

Principle: A battery drives a water pump, the drug is mixed in the cabin according to the required amount of water when used, and the water pump is opened for pond mouth sprinkling, which is simple to operate, evenly applied, greatly improves the efficiency of medication, and replaces the hard work of the previous scoop. What's more, a valve is installed on the opening on one side of the cabin, and when the pesticide is applied, the valve is opened, and one side is flooded, and the efficiency is improved again.

2.Bug traps

Principle: an incandescent lamp, a water pump (the power can be large or small), a mesh bag made of 200 mesh sieve sewn silk. Turn on the incandescent lamp at night, use the phototaxis characteristics of insects, make insects gather under the light, the water pump installed under the lamp extracts the cluster worms, the outlet of the pump is equipped with a mesh bag, the pumped water flow drives the insects into the mesh bag, filters the insects, extracts the net bag the next day, and scalds the insects to death with boiling water for harmless treatment.

There are many ponds, and dozens or even hundreds of catties of insects can be trapped overnight, which greatly improves the environment of the pond. This method is safe and efficient, and avoids the stress and even ** caused by the use of pesticides and insects to the river crab.

3.Tangkou bait machine

Principle: The principle of the device is simple, and the principle of using the bait machine in the fish pond is the same, and the motor drives the bait feeder. The biggest difference is that the feeding machine in the crab pond is installed on the boat and uses the battery to start, move the bait, which is convenient to operate, and one person can operate the boat, simplifying the previous operation mode of one person rowing and one person feeding bait, saving a labor force, especially the large pond mouth, the advantage is even more obvious.

The feeding device can also be used in the same way as the bait.

Insect traps, drug sprayers, and Tangkou bait machines are all very good gadgets and very practical.

For example, sprayers, traps, and feeding machines. This can improve efficiency, and it is also very convenient to use, and it is also very trouble-free.

Be sure to set up a trap for bugs, which can solve many problems, you can design some bait machines, you can set up some sprayers for drugs.

1.Pond culture model. Pond farmingWe have all heard of pond farming, whether it is fish farming, shrimp farming or other aquatic products, you can use the pond farming model, however, we still have to pay attention to the pond farming model also has some points that determine the success or failure of the pond crab farming model.

2.Rice farming model. The rice crab farming model is a popular model in recent years, which is mainly to breed crabs in the rice fields, which can increase the yield of the rice field and increase the yield of crabs. It can also reduce the cost of crab farming and improve the economic benefits of rice fields in general.

3.Cage culture mode. There are restrictions on this crab farming model, and the construction of breeding bases is mainly next to reservoirs and lakes, and these are necessary conditions for cage farming.

4.Crab and shrimp interculture. The shrimp and crab interculture model is a popular breeding model in recent years, which can improve the economic benefits of aquaculture.

Pond culture, paddy field culture, cage culture, shrimp and crab interculture, now it is generally more common to do 4 kinds of breeding mode, and it is also more conducive to management.

River crab is a better breeding model, and can create a high benefit, such a high-efficiency model, the choice of rice crab farming is better, rice field table, thank you together, can make full use of water resources, or rice and river crab double harvest, can improve the total yield per unit area, is a better efficient model.
