How to prevent and treat emaciation disease in farmed river snails

In our country, river snail farming is very common, especially in recent years with the continuous development of our country's farming industry and the continuous rise of the late-night snack industry, the market demand for river snails is growing. The most important thing in farming river snails is the prevention of river snail diseases, so let's take a look together with the editor below.

Causes of emaciation disease in river snails

Improper soil pH, temperature too high or too low.

Symptoms of emaciation disease in river snails

The body shrinks back into the shell, eats little or not at all, and remains in long-term dormancy or semi-dormancy.

Treatment of emaciation disease in river snails

① Soak in warm water at 22-25°C for 1 minute to make the river snails extend their heads, mix 0.25 of chloramphenicol with fortified glucose powder into 2,50 grams of concentrated feed, and feed continuously for 3-5 days

② Soak the river snails in 0.04% salt water or soda for 2 minutes to make the river snails extend their heads; feed dilute glucose water twice a day (glucose 50 grams plus chloramphenicol 500,000 units, mixed with 500 milliliters of water)

Characteristics of river snails  

It is a mollusk, and its body is divided into 3 parts: the head, the foot, and the visceral sac. The head has a mouth, eyes, tentacles, and other sensory organs. There is a shell outside the body. The foot muscle of the river snail is well developed and is located on the ventral side of the body. The membrane piece tightly attached to the sole of the foot is called the operculum. It is like a round lid. When encountering the unexpected or needing rest, the river snail retracts its body into the shell and, through contraction of the foot muscles, uses the operculum to cover the shell tightly. The blood color of the river snail is rather special, being white. River snails can be eaten, and the edible part is mainly its fleshy foot.  

River snails are distributed in most areas nationwide and can be caught in summer and autumn. In freshwater, Cipangopaludina cathayensis is commonly found. It is a medium-sized individual, with a shell height of about 44.4 mm and a width of 27.5 mm. The shell is nearly broadly conical, with 6-7 whorls, and each whorl expands outward. The height of the spiral part is greater than the height of the aperture, the body whorl is obviously swollen, the apex is sharp, the suture is relatively deep, the shell surface is smooth and without ribs, and it is yellowish brown. The aperture is nearly oval, with a complete, thin edge and a black rim. The operculum is a thin horny sheet, smaller than the aperture, with concentric growth lines, and the opercular nucleus is located in the center of the inner lip. Habitat.  

River snails generally grow in ponds or by reservoirs. If the water quality is poor, they are easily contaminated. Especially when eating them, if the feces inside the snails have not been fully discharged, there are many parasites; for example, Oncomelania snails are the host of schistosomes.

When farming river snails, it is very important to master the symptoms, causes, and most commonly used treatment methods of some common river snail diseases. Only by mastering some commonly used treatment methods can disease prevention methods be effectively applied and some unnecessary losses be reduced.
