In order to raise cages in cages in the main shrimp ponds, each cage can produce more than 100 kilograms of astragalus without increasing the yield of the shrimp, which increases the income of the aquaculture waters. The specific approach is as follows:
I. Pond selection
The water depth of the pond is about 1.5 meters, and the area is about 10 mu. It requires fresh water in the pond and convenient drainage and drainage. The pond can be planted with some aquatic plants such as Xiaomi Cao.
Second, shrimp breeding
In April and May, the use of small fish ponds to breed shrimp can be selected from the shrimp pond into the pool with a body length of 5 cm or more. After the shrimps emerge, the cages will be used to catch the broodstock and put them on the market. Generally, they are sold every 5 mu. The pond can cultivate 3 to 5 million shrimp.
Third, shrimp stocking
In early July, shrimps of 1.2-1.5 cm in length were stocked in clean-up shrimp ponds. About 40,000 were introduced per acre, and about 50 catfish were stocked per acre. In the first half or so of the first half of the year, the cultivation of water quality was mainly used to feed a small amount of feed. In the later period, the feed was mainly made of shrimp, and it was not allowed to overfeed so as to avoid excess feed and affect water quality. In addition, fresh water should be regularly added to the shrimp ponds to prevent the floating of the shrimps.
Fourth, cage settings
Place an open box with an area of ​​15-20 square meters at the water inlet of the pond, and fix it in a pool about 2 meters away from the pool with a bamboo pole, and put some aquatic plants such as water hyacinth and water peanuts in between. Each box is stocked with 50-100 grams/tail of about 40 kilograms.
V. Daily management
Every day, feed fresh fish in the cage to ensure that the eel is full. Check the cage regularly to prevent the mouse from biting and cause the eel to escape. Clean the sides of the tank and exchange the water inside and outside the tank to maintain the water quality. Fresh.
Sixth, timely arrest
After entering the winter, according to market conditions timely arrest, to ensure higher economic benefits.
