①Site selection of the open space in front of the house around the courtyard to build a pool, available groundwater or tap water as a source of aquaculture.
②Walls made of single brick, generally 2 square meters per eel pool area (2 meters long, 1 meter wide), inside and outside the wall and the bottom surface with cement, wall height 50 cm, the top of the wall made T-shaped, to prevent the escape function. The wall is 30 centimeters from the bottom of the pool to install a 10-centimeter diameter rubber hose overflow. The bottom of the pool to the drain to have a certain slope, in order to be able to drain the pool of water as a standard, the drain and the total drainage ditch connected. 20 centimeters from the bottom of the pool below the wall and the bottom surface of the pool are all tiled. Overflow and drain with wire to make anti-escape net cover, when not in use with cork tight.
3 cistern according to every 10 square meters of eel pool with 1.5 cubic meters of cistern ratio, with red bricks to build a cistern, inside and outside the walls of the flat corner, the bottom of the pool, all cement plaster. At the bottom of the pool, install a good water pipe. At the same time, the bottom surface of the pool to have a certain slope, often regularly cleaned sewage outlets, water outlets and sewage outlets are controlled by valves. Requirements for the cistern does not seepage, leakage, to ensure the safety of water supply. Cistern bottom plane should be 20 centimeters higher than the bottom plane of the breeding pool.
(2) Breeding technology
①Eel pond preparation eel pond built, first full of water, soaked for 10 days with 20 ppm (20 mg / liter) concentration of lime water on the pool and the environment for disinfection. One month before the release of seedlings, the pool was filled to a depth of 20 centimeters, and the tiles were soaked so that attached organisms and mossy mud grew on the tiles to reduce the reflection of light from the tiles. One week before the release of seedlings, placed around the pool after cleaning and disinfection of some water peanuts, leaving the center of the pool empty water for eels to feed. At the same time, each pool is stocked with a toad and a few loaches.
②Putting seedlings generally in early April can begin to buy eel seedlings. Eel seedling selection cage without trauma for the best, requires robust, swimming lively, neat specifications, about 30 per kilogram, specifications of the big difference to be stocked in separate pools. Before stocking, use 3% concentration of salt water to soak the eel fry for about 5 minutes. The amount of stocking to 5 kg per square meter is appropriate to ensure that the year's sales specifications of 150 grams or more.
3 baiting when the water temperature reaches 18 ℃ above, eels open feeding. But the eel seedling stocked in the pool in the first few days of appetite is very poor, generally do not take the initiative to eat. From the 4th day onwards, you can tame their feeding, start to live earthworms to lure them to open or fresh mussels cut into 4cm x 1cm x 1cm strips to tame the bait. After a few days, they can be fed artificial bait. With the appropriate amount of wheat flour, add fish meal, through the meat grinder to make a strip of bait, drying into a half-dry feeding. Feeding 1 time a day in the evening, feeding amount to the pool of eels in the total weight of 3% ~ 5% calculation. Generally placed in the pool of empty water, not only easy to observe the feeding situation, but also conducive to the removal of residual bait.
