Detailed Explanation of Key Techniques for Indoor Crayfish Farming

In recent years, crayfish have been a very popular farming project, because with the rise of late-night snacks, the price of crayfish has been climbing steadily. So, what techniques are involved in indoor crayfish farming? Let's take a look together!

1. Building the farming pond

Indoor farming ponds are generally built as cement ponds. The area of the cement pond needs to be built according to the number of crayfish being farmed and the indoor environment. The farming ponds need to be divided into nursery ponds, hatching ponds and grow-out ponds. The farm must be equipped with oxygen supply equipment, emergency power supply equipment, and a built water supply system and air supply system, to provide a good living environment for the crayfish.

2. Selecting and stocking shrimp fry

The selection of shrimp fry is also quite important, because indoor farming is inferior to outdoor conditions in all respects, so the requirements for shrimp fry are even stricter. Generally, choose shrimp fry with bright, glossy color, smooth body surface with no attachments, an intact body surface with no injuries, a strong physique with no diseases, and relatively high vitality. The survival rate of shrimp fry stocked this way will be a bit higher. Before stocking the shrimp fry, they need to be disinfected, and then placed into the farming pond, to avoid bacterial infection.

3. Feed feeding

Crayfish are generally fed with fresh small trash fish, river snail meat and specialized plant-based feed. The number of feedings and the amount of feed must be reasonable. If the feeding amount is too small, the crayfish will fight each other; if too much, it will cause the crayfish to overeat and die or waste the feed, leading to increased costs. Generally, under normal circumstances, feeding about three times a day is needed, but if the weather is bad, feeding just once is usually enough.

4. Daily management

Daily management of indoor farming is rather tedious. First, we must always pay attention to the water quality and water level in the farming pond and change the water in a timely manner. Second, we need to check whether the oxygen in the farming pond is sufficient and replenish oxygen in a timely manner. Also, after feeding in a timely manner, the feed residue must be promptly removed from the farming pond, to avoid polluting the water quality, which would increase the workload and affect the healthy growth of the crayfish. Finally, the farming pond must be disinfected regularly, to avoid triggering diseases that lead to the death of the crayfish.

5. Disease prevention and control

The pests and diseases of crayfish farming include gill rot disease, tail rot disease, black gill disease, ciliate disease, and other parasitic diseases such as Zoothamnium disease. Diseases like gill rot disease, tail rot disease and black gill disease are mainly caused by water pollution, so we must promptly remove impurities from the water, change the water, and use other methods to improve water quality. At the same time, the farming pond also needs to be disinfected and cleaned, and bleaching powder, methylene blue, and tea seed meal can respectively be used for pond splashing prevention and control. Zoothamnium disease can only be prevented and controlled by thoroughly clearing the pond, while ciliate disease can be prevented and controlled by soaking and washing with formalin solution, and simply controlling the stocking density.

The above are the techniques for indoor crayfish farming. I hope this can help everyone!
