How to Farm River Snails for High Yield? Here Comes the Detailed Technique Guide
Currently, river snails have become a very popular snack in many parts of our country. As market demand increases, wild river snails are becoming fewer and fewer, and artificially farming river snails is becoming more and more popular. Below is an introduction to the detailed guide to high-yield river snail farming techniques.
I. Selection of Snail Seed Stock
The selection of seed river snails is a fundamental condition for successful river snail farming. Many farming beginners actually do not know much about river snails, so when selecting seed snails they cannot tell which are high-quality seed stock. This makes it very easy to be deceived, causing great losses. In fact, when selecting seed snails, we only need to choose river snails that are free of pests and diseases, have no damage to any body parts, look relatively robust, are suitable for local growth, and are relatively uniform in size.
II. Pond Cleaning
Many people have seen the environment where wild river snails grow and think that pond cleaning is an unnecessary task, but this is actually not the case. It is precisely because of this that wild river snails are becoming fewer and fewer and their reproductive capacity is further degrading. So when farming them, we need to pay attention: before farming, the excess silt must be cleaned out, then quicklime should be used for disinfection, and after disinfection is complete, the river snails can be stocked. In addition, during the later stages of farming, proper pond cleaning and disinfection are also needed, so as to ensure the quality of river snail growth.
III. Water Quality Adjustment
In river snail farming, adjusting water quality is very important. The water used for river snail farming needs to be relatively fertile, so we must reasonably control the supply of fertilizer. Second, we need to change the water regularly to ensure the water quality is suitable for the normal growth of river snails. Especially during the breeding period of river snails, water quality has a very large impact on their reproductive output. Also, when summer temperatures are relatively high and winter temperatures are relatively low, we need to scientifically adjust the water temperature, which helps promote the growth of river snails. Finally, the water level in river snail farming water bodies should not be too deep; generally the maximum should not exceed 40cm and the minimum should not be lower than 20cm. One more point is to properly adjust the pH value of the farming water body; basically, every half month appropriately add some quicklime to neutralize the acidity and alkalinity of the water body.
IV. Bait and Feed
The river snail is an omnivorous organism, so first we can apply an appropriate amount of fertilizer, which can increase the plankton in the water and provide a certain long-term food source for the river snails. Second, they mainly feed on aquatic plants and algae. When feeding them, we usually give vegetables, melons and fruits, animal offal, rapeseed cake, and the like, but we must not feed poor-quality or spoiled feed, and we must promptly clean out feed residues to avoid polluting the water quality. Also, when feeding, it cannot be fed whole; it should be chopped up before feeding, and the amount fed each time should be based on the specific condition of the river snails. The frequency of feeding should not be too often; it is best to feed once every two days.
The above is Tuliu.com's introduction to river snail farming techniques. Many people have raised river snails, or have seen the growing environment of river snails in certain places, but sometimes what we see is not necessarily truly reliable, so everyone should still carry out farming according to professional farming techniques.
