Summary The effects of environmental factors, such as the nature of paddy soil, the presence of rice plants and weeds and applications of compost and weed-killers, on the behavior, growth and reproduction of the mud snail (Cipangopaludina japonica, an important paddy-soil dweller in Japan) were studied. The types of water-soluble substances in the soil and the softness of the mud make paddy soil a suitable habitat for this snail. The snail avoids soils that bear rice plants and weeds, preferring soils without higher plants. Feeding experiments revealed that the snail consumes a great deal of bacterial materials, such as detritus and sludge compost, suggesting that the sewage sludge produced from wastewater-treatment installations can be decreased by the snail if it is applied to paddy fields as sludge compost.
