Culture Technology of Micro-running Water Monopterus albus

Construction of running water tank

Aquaculture ponds can be built indoors or outdoors, each pool area 2~5m2, pool depth of 24 cm, rectangular, brick floor, single brick upright and arranged into a wall, polished with cement. The eaves around the wall are protected, the two ends of the pool are 20 cm high above the bottom of the pool, respectively set into, drain, equipped with appropriate aperture of the escape net or grid, the bottom of the pool covered with sand. When building multiple pools, it can be a single joint type. A reservoir needs to be built upstream, and after installing the regulating valve and opening the valve, the pool water is required to flow freely in each pool in turn, and finally discharged.

Selection of seedlings

The species of eel come from artificial cultivation or natural collection. Physical requirements are robust, consistent in size, bright in color, no trauma, 25g / m ~ 30g per tail, 100g / m ~ 150 young eel per square meter, and sterilized with 30g / L salt water or potassium permanganate before entering the pool.

Feeding and management

1. The fodder of Monopterus Albus can be fed with earthworms, fresh fish and shrimp, or artificial compound feed.

2. The eel seedlings were domesticated after entering the pond for 3 days, and the domestication period was about 15 days. At first, the bait can be given in the evening, and then gradually advanced to 14-15:00 in the afternoon or around 10:00 in the morning, the daily feeding amount is 6%-7% of the total body weight of the eel, and it is fed twice in the morning and evening. The bait of ricefield eel should also be "determined".

3. In the middle of summer, it is best to plant some aquatic plants in the pond or build a shed for shade.

4, residual bait, feces and other dirt, make it float and discharge into a pool in turn, until finally discharged from the culture pond.

5. Always patrol the pool, observe the water quality and water temperature, and pay attention to the damage caused by cats and mice.

Prevention of eel disease

The disease of yellow eel is not easy to find, so it is mainly to be prevented. In addition to disinfecting eel species before releasing seedlings, quicklime is generally sprinkled all over the pond every 15 days during the breeding period, with a dosage of 510g / m? 2. During the disease season, low concentration solutions such as 0.1 g / m ~ 3 bleach or 0.2 g / m ~ 3 trichlorfon or 0.7 g / m ~ 3 copper sulfate were regularly applied in the eel pond.
