The optimum temperature for the growth of snails is 20-26 C. When the water temperature exceeds 30°C, snails will burrow into the soil to escape the heat and stop growing. The quality of water is also one of the main factors that affect the success or failure of snail culture, so it is necessary to ensure good water quality during culture. Snail is an omnivore, so it must not be fed with spoiled and corrupt feed, and the remaining feed should be fished out and cleaned up in time to avoid polluting the water quality.

First, why do you say that raising snails is a loss?

1, the growth temperature of snail is 20-26? C, at this temperature, the intake of snails will increase and grow rapidly. But when the water temperature of its growth exceeds 30? C, the snail will burrow into the soil to escape the heat. At this time, it will not eat and stop growing. In the long run, the meat quality of snails will be affected and become hard and boring.

2. The quality of water is also very important for the cultivation of river snails, and the water quality must be ensured during cultivation. Water containing a lot of iron and sulfur substances is not suitable for breeding snails, because the iron content in this water is too high, and a large number of snails will die if they are cultured in it. Moreover, the mortality rate of snails growing under this water quality is extremely high. Even if they can survive, there is a lot of red rust on the snail shell and the snail meat will be brownish red.

3. The snail is an omnivore. Its main food is deep-water plants and algae. When it is cultivated artificially, it can be fed with some vegetables and fruits. However, when feeding, we should pay attention to it. We must not feed it with spoiled and corrupt feed. In addition, we must remove the remaining feed in time to avoid polluting the water quality.

Second, what do snails eat?

1, Oncomelania hupensis prefers to grow in waters with rich humus in sediment, such as lakes, ponds, depressions or rivers with slow water flow. Their main food sources are microorganisms and humus in the bottom soil, phytoplankton and moss in the water, and they can be fed some artificial compound feed, fruits and vegetables, vegetable leaves, bean cakes and various animal scraps during artificial breeding.

2. The specific feeding quantity of river snail must be adjusted according to its feeding situation, and the general feeding quantity is 1-3% of the total weight of river snail. The feed can be put in a different place. When feeding, the feed must be put separately, usually about 3 days 1 time.

Third, how to feed snails

1, snail larvae

Feeding should be started two weeks after delivery, and egg yolk should be used for feeding. After 1-2 days, it can be fed with natural bait. When feeding, young snails will lick the bait with their teeth and tongues, so when feeding solid bait, they must be soaked soft.

2. Young snails

After the snails are put into the pond, they can start feeding some vegetables, rice bran, fish offal or tea cakes and bean cakes. When feeding, it should be noted that vegetables and fish viscera should be chopped and mixed with rice bran and other feeds, and the feed such as vegetable cakes and bean cakes should be soaked and softened so that snails can eat.

3. Oncomelania

Adult snails can be fed freely at this time, but the number and frequency of feeding should be paid attention to, about once every 1-2 days, and the feeding amount must be determined according to the feeding situation of snails.
