Seasonal variations of Molluscan forms in relation to lake water characteristics in Koothaippar lake ecosystem, Tiruchirappalli District, Tamil Nadu, South India.
Wetlands support many aquatic organisms especially molluscan forms. Studies on the status and distribution of fresh water molluscans are lacking because of difficulties in taxonomy. The current study was carried out at the Koothaippar lake, Tiruchirappalli district, Tamil Nadu, from October 2013 to June 2014. Hand picking and quadrate methods were applied for the collection of molluscan forms in the lake. Five different fresh water molluscan species comprising two orders and three different families were recorded, besides two unidentified molluscan forms were also recorded during the study. In addition, the study investigated the effects of physico - chemical parameters of water on the distribution of freshwater molluscan forms in the Koothaippar wetlands. The study showed that the physico-chemical parameters of water influenced the distribution and abundance of fresh water molluscan.
Keywords: Molluscan forms, freshwater wetlands, distribution, physic-chemical parameters of water, interaction and conservation.
