Can we raise ricefield eel in newly dug ponds?

Monopterus Albus can be raised, but the area and depth of the pond must be controlled according to the size of the eel, and it is necessary to dig deeper when digging the pond in order to prevent the water temperature from getting too high in summer. It is convenient for Monopterus Albus to make holes with about 40 cm of organic fertilizer soil in the pond, and the fence and design to prevent the escape of Monopterus Albus need to be done. Ponds need regular fertilization, disinfection to ensure water quality, prevention of disease, proper addition of bait, and daily supervision to prevent rice field eel and fish from being stolen.

I. matters needing attention in digging and building ponds

1. Monopterus Albus is agile and easy to escape. When digging the pond, the practicability of the pond should be considered according to the characteristics of Monopterus Albus. The area of the pond had better be controlled at about 10-20 square meters, and the pond depth should be different according to the size of Monopterus Albus. Small Monopterus Albus adapts to a depth of about 40 cm, while adult Monopterus Albus lives in a pond depth of about 1 meter.

2, the pond had better choose brick cement plastering or concrete, in order to prevent the high summer temperature caused by high water temperature, affecting the growth of ricefield eel, it is best to dig deeper when digging the pond, and some soil can be laid at the bottom of the pond if necessary. make sure the pond is smooth and watertight. The T-shaped pond mouth can prevent Monopterus Albus from escaping, and the drains and inlets of the pond should also be guarded to prevent the Monopterus Albus from escaping with the influent. In addition, in order to facilitate the Monopterus Albus to make holes in the pond, it is necessary to put about 40 centimeters of soft and moderate organic soil in the pond.

II. Daily management matters

1. Regular fertilization

According to different seasons, the fertilizer and quantity are different. Take 670 square meters as an example, 1 kg of organic manure is needed in February. After entering summer, it is mainly phosphate fertilizer and nitrogen fertilizer, and the fertilization method is changed and needs to be spread separately. Fertilization should be chosen in the sunny morning, sprinkle fertilizer with water all over the pond, apply 5 kg phosphate fertilizer on the first day, and 7.5 kg ammonium bicarbonate on the second day. Fertilize regularly every half a month.

2. Bait and water quality assurance

Silver carp can make the water quality in the pond more fertile. In order to ensure that Monopterus Albus has enough bait fish, the number of bait fish will increase with the increase of Monopterus Albus, but too much bait fish will cause insufficient food for silver carp and lead to the imbalance of biological proportion in the pond. therefore, in addition to feeding bait fish, it is necessary to put in some pellet feed made of corn, cake, wheat bran, fish bone meal and vitamins twice a day.

Under the condition of ensuring adequate bait, the change of water quality should be observed at any time. If there is a fish floating head, the oxygen equipment needs to be turned on immediately, and the waste water needs to be discharged regularly and injected with new water every week to ensure the water quality of the pond.

3. Pond management and disease prevention

Farmers need to observe the situation of ricefield eel and fish at any time by the edge of the fish pond every day, and can also prevent people from stealing fish and eels.

In addition to the daily supervision of ponds, it is also necessary to pay close attention to the development of fish and rice field eel and apply fish medicine regularly to prevent fish diseases. In addition to changing water regularly every week, fish ponds also need to use quicklime or bleach to disinfect the water quality every half a month in summer. The application of fish medicine and disinfection time must be staggered with the fertilization time, so as not to affect the effect of disinfection and fertilizer production.
