Recently, we when to the paddy field in early morning, about 6.30 am, to look for the freshwater snails. During observation, there were no Lymnaied snails was present there. Before this, studies have been done in that area, the liver fluke infection has occurred in cattle. But, still did not find the presence of snails that act as intermediate host for this disease.Therefore, we want to know when and where to find the snail intermediate host that causes liver fluke disease in cattle. Thanks.
Lymnaea sp. are usually abundant during certain seasons. usually they are found to be floating when sunlight is rich
I find that with Lymnaied snails you can find them almost year round in many parts of the world. If you really believe the infections are coming from the ponds on the field you should start to check around the edges of the water and perhaps on emergent vegetation. Since Lymnaied snails are amphibious I often find them 5-10 cm or so out of the water sitting on a substrata like cement or plants.
I agree with Will K Reeves, they are found to be attached with vegetation normally but when the temperature on the upper part of water bodies gets higher they seems to be floating on the surface of water
