How to design the best pond for raising Monopterus albus?
Pond stocking is not recommended. Nowadays, many Monopterus albus farmers are like this, and it is better to use the latest cage culture method, but if you want to disagree, I'll tell you. 1. Selection of natural conditions; Generally, the ponds for breeding Monopterus albus are built in places with shelter from the wind and sunshine, sufficient water sources, pollution-free water quality and convenient water intake and drainage. 2. Pond construction: Monopterus albus culture ponds can be rectangular or square, and the depth of ponds is required to be L.-L.2m.. Culture ponds are divided into two types: soil ponds and cement ponds. The ridges of the soil ponds are made of hard soil, with the bottom of the ridges being .5m wide and the top of the ridges being .3m wide. The bottom of the ponds is compacted, and the four walls and the bottom are pressed with plastic films or plastic tarpaulins. Contiguous ponds should be designed and constructed in a unified way, and the water inlet and outlet should be equipped with escape-proof and leakage-proof facilities. 3. Bottom condition: The pond for breeding Monopterus albus requires silt with a thickness of .2-.3 meters and rich in organic matter. River mud with grass can be dug in early spring every year, and aquatic plants such as water hyacinth, peanut and water bamboo can be planted in the pond, so that the coverage rate of aquatic plants in the pond can reach about 3%. When stacking ridges, be careful not to make the water in the pond form dead corners, which will affect the water exchange effect. 4. Removal of wild miscellaneous fish: Before stocking eel seedlings, fish with low economic value, which compete with and harm eel seedlings, should be removed from the pond. At the inlet and outlet of the pond, .3 cm mesh cloth can be used to make fish-stopping facilities. 5. Cleaning and disinfection of the pond: When the natural water temperature reaches above 1℃, it is necessary to make preparations. First, drain the accumulated water in the pond and expose it for 2 days. Then clean the periphery and bottom of the pond, disinfect the medicine 1 days before the seed is purchased, use 22-25g/m2 of quicklime with 1cm of water, after the quicklime is dissolved, sprinkle it all over the pond while it is hot, completely kill harmful bacteria and parasites at the bottom of the pond, and create a good and stable pond environment.
