What is the typical yield per mu for crayfish farming?

The yield per mu of crayfish farming is divided into intensive farming and ordinary farming. Intensive farming can achieve a yield of about 400-600 jin, while ordinary farming can achieve a yield of about 300 jin.

What factors affect the yield per mu of crayfish farming

1. Farming density

Maintaining a reasonable farming density is conducive to giving full play to the productivity of the pond, and can also increase the yield, size and economic benefits of the crayfish. If the farming density is increased solely in pursuit of yield, it will increase the difficulty of farming management, and the crayfish will also kill each other in fighting for living space.

2. Stocking size

When stocking crayfish, attention should be paid to the fact that the stocking sizes should not differ too much, otherwise large, medium and small sizes must be stocked in separate ponds. During the grow-out process, attention should also be paid to the size of the crayfish. If the sizes are uneven, large crayfish will eat small ones, greatly reducing the survival rate and affecting the increase in farming yield.

3. Correct feeding

Feeding is the key to farming crayfish. When feeding, attention should be paid to 5 aspects: the type of feed, the palatability of the feed, the determination of the feeding amount, the feeding method and the feeding time. Crayfish are omnivorous animals and can consume both animal feed and plant feed.
