Four secret ways to raise ricefield eel

Raising ricefield eel in cage is the most economical and cost-effective way of breeding. Ren Chao, special agent for science and technology in the Central District of Neijiang City, Sichuan Province, introduced four tips for raising ricefield eel in cages.

The young eel is selected to observe the body surface. Monopterus Albus has red blood clots on the body surface, which is rotten skin disease; the tail is white and flocculent villi, which is water mold disease; the head is large and thin, and even shows stiff curls and trembles, which is a parasitic disease in the body; the anus is red, swollen and inflamed protruding, which is enteritis. In addition, the young eels with weak body, less mucus and floating head are all bad eels and should be eliminated.

Pond disinfection

The pool should be fully disinfected before putting down the seedlings. After soaking the cement pool with quicklime water for 3 to 7 days, and then soaking in clean water for 15 to 30 days, it would be better for the bottom of the pool to grow moss. After disinfection, Misgurnus anguillicaudatus was put into the pond for disinfection detection, such as Loach floating head in 1-4 hours, swimming crazily in the water, or death, indicating that the cement pool disinfection has not yet achieved the effect. The time of disinfection and soaking should be prolonged.

Cast a net to plant grass

Raising eels in cages is inseparable from aquatic plants. Aquatic plants have the function of shading and letting Monopterus Albus attach. Varieties generally choose water hyacinth and cross-river vine. The dung of Monopterus Albus happens to be the fertilizer of aquatic plants. Aquatic plants generally account for about 70% or 80% of the net cage or cement pool.

Seedling domestication

The trick to getting out of seedlings is to look at the weather. Should pay attention to the weather changes 5-7 days in advance to ensure that the seedlings are sunny; the water temperature is stable at about 25 degrees Celsius; the temperature difference between day and night does not exceed 5 degrees Celsius; the maximum water temperature does not exceed 35 degrees; put aside the laying and spawning period of Monopterus Albus. Seedlings can be planted when these conditions are met.

Under the classification of large and small seedlings

Domestication is critical to the growth and survival of Monopterus Albus. The seedlings were lowered for 3 to 5 days, and the young eels that did not eat or opened a small amount of food were treated in time. Domesticated eel seedlings can be fed without bait two to three days before the seedling pond, and then fed later. The bait can be composed of maggots, earthworms, snail meat and so on.

In the process of domestication, it is best to do three things: first, listen to whether the rice field eel eels eat evenly; second, see whether there are more or less rice field eels that open their mouth to eat; and third, observe the amount of bait left the next morning, whether there is any abnormal situation of the rice field eel and whether the rice field eel leaves the aquatic plants and comes out during the day.
