Attention must be paid to the summer to prevent high temperatures, because the paddy water is shallow, the water temperature in the summer may reach the upper limit of the lethal temperature; and the winter overwintering of the mud bottom of the organic matter content should not be too high, otherwise it is easy to produce toxic substances and the impact of snail overwintering.
2, snails are sensitive to the amount of dissolved oxygen in the water, the normal life requirements of dissolved oxygen in the water per liter in more than 4 milligrams, when down to 3.5 milligrams, the appetite will decline, when down to 1.5 milligrams will cause death.
3, the snail's breeding season in June-July (the conditions of the place in the fall will also lay eggs once), if you consider their own reproduction, it is best not to raise carp in the paddy field of the snail, otherwise the small snail will be ingested by the carp.
4, the use of pesticides in the paddy field should not be used as much as possible or less; that is, the use of low-toxicity pesticides should also be used, and should be used on a sunny day; it is appropriate to use half and half in the paddy field.
5, in the growing season can be regularly used organic fertilizer, the principle is a small number of times, should not be too much fertilizer.
6, the breeding process is best to have a certain micro-flow environment to ensure that the dissolved oxygen in the water, but must pay attention to the water source, do not cite pesticides in the water.
7, you can consider the snails and leeches, loaches, eels and other mixed farming, the economic benefits are better.
8, snails eat what food
In general, the breeding pool first cast some manure to cultivate plankton to provide bait for snails. The amount of fertilizer depends on the bottom of the snail pool, depending on the fat and thin. After the snail into the pool, feeding green vegetables, rice bran, fish offal or vegetable cake, bean cake. Green vegetables, fish offal should be chopped and rice bran and other feed mix feeding. Vegetable cake, bean cake and so on should be soaked and softened, so as to facilitate the ingestion of snails.
The amount of feeding depends on the snail ingestion, generally 1%-3% of the total amount of snails, feeding every 2-3 days. Feeding time every morning, the location of the bait does not have to be fixed, the feed spaced out. When the temperature is lower than 15 ℃ or higher than 30 ℃, do not need to bait.
