Techniques of indoor crayfish culture

In recent years, crayfish has been a very popular breeding project, because with the popularity of midnight snacks, the price of crayfish has gone up. So, what are the techniques of indoor crayfish farming? Let's get to know it together.

1. Aquaculture pond construction

The construction of indoor culture ponds is generally built by cement ponds, and the area of cement ponds needs to be built according to the number of crayfish and indoor environment, and the culture ponds need to be divided into seedling ponds, incubation ponds and cultivation ponds. The breeding farm should be equipped with oxygen supply equipment and emergency power supply equipment, build a good water supply system and gas supply system, and provide a good living environment for crayfish.

2. Selection and stocking of shrimp fry

The choice of shrimp seedlings is also more important, because indoor culture in all aspects of factors are not external conditions of high quality, so the requirements of shrimp seedlings are more stringent. Generally, choose shrimp seedlings with bright color, smooth body surface, no attachment, intact body surface, strong physique, no disease, and more dynamic shrimp seedlings, so that the survival rate of shrimp seedlings will be higher, before the shrimp seedlings are released. Shrimp seedlings need to be sterilized and then put into the culture pond to avoid bacterial infection.

3. Feed feeding

Crayfish are generally fed with fresh miscellaneous fish, snail meat and special plant feed, and the times of feeding and the amount of feed should be reasonable. if the feeding amount is too little, the crayfish will have a fight incident. too much will lead to crayfish to death or waste of feed, resulting in an increase in cost. generally, under normal circumstances, it is necessary to feed about three times a day, but if the weather is bad, it can be fed once.

4. Daily management

The daily management of indoor culture is relatively tedious. First of all, we should always pay attention to the water quality and water level in the culture pond and change the water in time. Secondly, we should test whether the oxygen in the culture pond is sufficient and replenish oxygen in time, and after timely feeding, we should timely fish the feed residue out of the culture pond so as not to pollute the water quality, increase the workload and affect the healthy growth of crayfish. Finally, the culture pond should be disinfected regularly so as not to cause disease and lead to the death of crayfish.

5. Disease control

The diseases and insect pests in crayfish culture include Gill rot disease, tail rot disease, black Gill disease, Polygoniasis, ciliosis and other parasitic diseases, such as Gill rot disease, tail rot disease and black Gill disease, which are mainly caused by water pollution, so we should timely remove impurities from the water, change water and use other ways to improve water quality. at the same time, we also need to disinfect and clean up the culture ponds. At the same time, bleaching powder, methylene blue and tea meal can be used for pond control, while polyzoonosis needs thorough pond cleaning to control ciliosis, and formalin solution can be used to control ciliosis. and control the stocking density.

These are the techniques of indoor crayfish culture. I hope scientific research will help you!
