The first thing is to buy an escape net. The choice of net must be strong and durable. It must be able to withstand salt and alkali, corrosion and flood. Better pave more roads. After all, eel likes to drill around the corner all the time. When laying, the silt with a depth of 1 m is dug out, then the net is put down and leveled with silt, but it needs to be replaced every three years. Because it is free-range, fish often run away or get lost.
It is very important to reinforce the ridge. Firstly, the ridge was widened and raised for loach cultivation in rice fields. General ridge height 1250px, width 875px. The ridge should be at least 750px above the water surface, with steep slope and firm ridge. There are two ways to cultivate Monopterus albus and Misgurnus anguillicaudatus in rice fields. One method is to put loach and loach directly without transforming paddy fields. The other way is to transform paddy fields into rice and shrimp fields, leaving inner ridges and deep ditches.
When building a ridge, it must be built firmly. It is what we often say: reinforcement, widening and heightening. Misgurnus anguillicaudatus and eels will not go ashore directly, but if the dam breaks, the water enters the mouse hole and rises over the ridge, they will all escape. However, at present, there is a new farming mode of Monopterus albus and Misgurnus anguillicaudatus, that is, mixed farming in rice fields, in order to increase the extra income of rice fields. Therefore, we must be fully prepared in this regard, especially in heavy rain.
