First, preparation before stocking.
1. Requirements for pond construction: the loach pond area needs to be 5 acres to 10 acres, the depth of the pond water needs to be 1.5 meters to 1.8 meters, the pH value of the silt at the bottom of the pond must be neutral, and the pond wall must be compacted to ensure that it does not leak. , the water inlet and drainage of the pond should be convenient, the surrounding area of ??the farm should be quiet, the water quality should be good and free of pollution, each acre of pond should be equipped with an aerator, and anti-rat nets should be set up around the pond.
2. Clean the pond: Before planting loach seedlings in early spring, clean the pond with quicklime 20 days in advance, and then use aeration particles and compound salt to improve the water quality. After cleaning the pond and adding water again, plant some water spinach, lotus root, wild rice, water hyacinth, and water peanut in the pond. This will help improve the water quality and protect the loach from the sun.
3. Fertilizer water quality: Sprinkle some amino acid fertilizer in the pond 10 days before stocking, so that the aquatic animals and plants that loaches like to eat will reproduce faster.
Second, stock loach seedlings.
1. Select loach seedlings: Seedlings should be purchased that swim fast, have no skin damage, are healthy and disease-free, and are 3 cm to 4 cm long. When transporting the seedlings, be careful not to injure the seedlings. After transporting the seedlings to the pond, spray them with salt water before stocking them.
2. Stocking density: The best time to stock seedlings is mid-May. 10,000 loach seedlings can be stocked per acre.
Third, breeding management.
1. Feeding: After placing the loach seedlings, put 6 buckets specially filled with loach feed next to the pond. Each bucket should be filled with 10 kilograms of special expanded feed for loach, and feed them continuously for 3 days. After the feed in the bucket is used up every day, another 10 kilograms of feed will be filled and the feeding will continue. The diameter of the feed should be 0.3 mm at the beginning. After 10 days of feeding, feed with a diameter of 0.5 mm should be used, and then 0.8 mm feed should be fed for another 10 days until it is one month old. After one month of cultivation, use a special feeding machine for feeding. Feeding time should be between 7 am and 8 am. Two feeding machines should be installed per acre of pond.
2. Water quality management: Change the water frequently after stocking loach seedlings. Every time you change the water, drain out part of the pool water first, and then add new water. Use quicklime to adjust the water quality every week. The best color of the pool water is yellow-green.
3. Disease prevention: Sprinkle yeast, EM bacteria and other biological agents in the pool at regular intervals. This can adjust the water quality and improve the immunity of the loach, and the chance of the loach getting sick will be reduced. .
4. Fishing: It takes about 3 to 5 months from stocking loach to fishing. Loach can be harvested and marketed as long as it grows to 10 centimeters long.
