Abstract

The snails are very important part of the food chain and excellent source of calcium in the ecosystem for the birds during their breeding season. They are intermediate hosts of many parasites. This study was conducted to estimate the species relative abundance, the effects of abiotic factors on different snail species, which led us to the finding of the indicator species in the agro ecosystem of Faisalabad,. Total of 19,290 snails were collected from crop lands of 24 villages. The species were identified with the help of recent identification keys and RAPD markers. Three snail species i.e. Physa fontinalis, Zooctecus insularis and Ceciliodes acicula were found completely absent from most of the villages except a few, indicating that the possible cause may be presence of arsenic. Other abiotic factors i.e. Cd, Pb, pH and Electrical conductivity are within the permissible limits. These species can be considered extremely important for biomonitoring. This study can be used as a predictive model to estimate environmental degradation.
