1, digging fish ponds
Choose a place with sunny ventilation and convenient access to water. After pushing the eel pond into shape with a pusher, clean up the surrounding ridges with a excavator, and then install it into the drainage pipe. Choose a 300 cm cement culvert or use a submersible pump to directly feed water.
2, cage installation
The cage is made of PVC knottless mesh or pure white four-kill knottless mesh, with the specification of 2m× 3m or 2m× 2m. The water depth of the cage is 50cm-80cm, and the water outlet height is not less than 50cm. The cage is fixed with wooden stakes and iron wires, or bamboo poles. Soak the cage in water 7 to 10 days before sowing, so as to make it adhere to algae, so as to avoid friction and damage when the eel enters the net.
3, pond cleaning disinfection
After the cage is installed, the pond is cleaned with quicklime, and the amount of quicklime is used.
Dry cleaning pond is 80 to 100 kilograms per mu.
Clear pond with water 150 to 200 kg.
The aquatic plants are put into the box with 2~3% salt or 10ppm bleaching powder, and the aquatic plants are soaked and disinfected to remove leeches.
4. Put in white fish
About 30 silver carp, Hualien 10, five grass carp, one bream ten tail, one herring and white lotus are put into each mu to purify the water. Grass carp and bream mainly remove weeds in the pond, and herring eats snails and mussels at the bottom of the pond.
5. Buy eel fry
It is best to enter the eel fry in sunny days. After the fry come back, we should distinguish the size, remove the red fry and keep the healthy eel fry. The specifications are about 30 fish per catty, about 2× 2m cage12kg, about 2× 3m cage18kg, and about 1 kg 15.
6, put the seedlings to train food
After releasing the seedlings, we should first train for food, because after the eel larvae come back, there is an adaptation stage. When we train for food, we should choose fresh earthworms or red worm water earthworms, cooperate with fresh fish, and gradually add feed after one week, and gradually increase the amount of feed, subject to the fact that the eel is finished 10 to 20 minutes after feeding, and gradually increase the amount and enter normal management.
7. Control the feeding amount
The normal food intake of Monopterus albus is calculated according to fresh materials.
The daily feeding amount is 8%- 10% of the body weight of Monopterus albus, and the daily feeding amount is 2.5%-3% of the body weight of Monopterus albus according to the formula feed.
Monopterus albus can't be fed as much as it can. It is necessary to control the food intake of Monopterus albus within a predetermined range to reduce the burden of liver and gallbladder.
8, safe medication
The use of pesticides should be reduced in eel breeding, which is highly toxic. Don't use highly toxic pesticides when parasites appear. Insecticides not only kill insects, but also bring burdens to eel's liver, so choose safe and non-toxic products when there are parasites.
In recent years, the market prospect of Monopterus albus breeding is good, and many people are eager to try. However, Monopterus albus breeding is no better than others, and it needs to master precise technology. Otherwise, Monopterus albus will die easily, not only making no money, but losing money. Therefore, we must pay attention to its growth habits and ecological breeding.
