CATDOLL : CATDOLL: Greenhouse eel farming technology What are the greenhouse eel farming technologies?

1. To raise eels in a greenhouse, you need to build a pool, each pool is about 10 square meters and 40 centimeters deep. After disinfecting the pool, you can put the eels in. Generally, each pool is filled with about 5 kilograms of eel fry.

2. Meat should be fed daily, including earthworms, snail meat, clam meat, etc., and silkworm pupae, fish meal, etc. can be added later. Artificial seedlings are required after a period of breeding.

3. After the pool is built, plug the main drain, fill the pool with water, soak for 5 to 7 days, drain the pool, plug the drainage hole at the bottom, drain the water to keep the water depth of each pool 5 cm, and have a slight flow of water. Then you can stock the eels. Eels need to be disinfected before stocking. Add 8 grams of copper sulfate and 10 grams of bleaching powder per ton of water, stir well, and soak the eels in the liquid for 20 to 30 minutes after dissolving (set the water temperature to 10 to 15 ° C).

4. After a period of breeding, if the eels in the same pond are uneven in size, they should be separated and raised in time. Wash and expose the feeding table regularly, or disinfect it with bleaching powder and other drugs. Disinfect the water body with 20 grams of quicklime per square meter every 5-7 days. Change the water in time. For eel ponds that are not micro-flowing water, add new water to the pond once every 5 days during the high temperature season, and drain the same volume of old water at the same time. In winter and early spring, remove the straw curtain from the plastic shed from 10 am to 3 pm on sunny days, and cover the curtain to keep warm at other times.
