Loach breeding technology

1. Pond construction: Choose the place where the shelter is sunny, easy to divert water, weak alkaline sediment, and no pollution. The pond can be cement pool or earthen pond. The earthen pond is made to be durable and free from holes, and the bottom of the pool is spread with 20-30 cm of fat. The inlet and outlet are stopped by wire or plastic mesh, and the bottom of the tank is inclined to the outlet.

2. Qingchi Disinfection and Placing of Straw Bales: 2 weeks before stocking, 80 kg of quicklime dry clearing ponds per acre, and 400 kg of organic fertilizer per acre after 3 days. Then dry the mold-free corn stalks, straw and other straws, bundle them with 10th wire into bundles of straw with a diameter of 40-50 cm, and then use a wooden rod with a diameter of 5-8 cm to wrap the bundles of straw on the bundle. Eyes, after the use of stone, etc. for the sinking stone, straw bundles parallel to sink into the bottom of the pool, put straw bales 15 to 20 per mu, and finally to the pond water injection to 80 to 130 cm.

3. Feeding quail species: Wild scorpions that are artificially propagated or captured can be used as seeds. Loach species require individuals to be robust and uniform in size. Before stocking, soak it in 3% saline for 5 to 10 minutes. The amount to be put is between 25,000 and 30,000 per mu; in places where there are conditions, polyculture with cockroaches, cockroaches, squid, etc. are carried out.

4. Feeding management: on the basis of providing natural food, increase the feeding of animal feeds such as aphids, cockroaches, quail meats, fish meal, miscellaneous fish, livestock and poultry waste, and wheat bran, rice bran, bean dregs, cakes and other plants Sex feed, or artificial compound feed. Normally feed every day on the afternoon and afternoon, and the daily feed is 5% to 10% of the loach's body weight. Feeding should be based on water quality, weather, and food conditions. Water quality management should maintain "fat, live, tender and cool". If it is found that the muddy surface is "swallowing" or floating on the surface of the water, fertilization should be stopped immediately and fresh water should be injected. In the summer and autumn hot season, change the water every 7 days, changing the water every time by 50%.
