Seasonal Variation of Water Quality Modulated Redox Regulatory System in the Apple Snail Pila globosa and Its Use as a Bioindicator Species in Freshwater Ecosystems across India

Studies on oxidative stress physiology molluscs to monitor the aquatic environment, influenced by pollutants and stressors are very limited in general Indian apple snails, P. globosa particular. The main focus of present study was establish baseline data a redox regulatory system sampled across subcontinent. Snails were from different zones India three seasons (rainy, summer winter) (levels antioxidant enzyme activities small molecules) indicator (lipid peroxidation) analyzed. observed elevated lipid peroxidation level season accompanied with pH, salinity temperature indicates induction stress. In season, superoxide dismutase (SOD), catalase (CAT) glutathione reductase (GR) enzymes augmented, whereas free -SH group peroxidase (GPx) glutathione-S-transferase (GST) found be increased. Similarly, correlation analysis between parameters revealed that SOD, CAT GR pH as well salinity, strongly correlated temperature. Collectively, our indicate use model organism access freshwater environment determining status this animal.
