Determination of Rate of Shell Accretion in Pesticide Induced Fresh Water Bivalve, Parreysia Corrugata
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2017, Vol 1, Issue 4
Abstract
Rate of shell accretion was studied in the freshwater bivalve, Parreysia corrugata exposed to chronic treatment of pesticides; quinalphos (0.108 ppm) and thiodan (0.0708 ppm). The thickness of the accreted part was maximum at umbo, moderate in the middle and was minimum at the margin of the shell in bivalves of all three groups. Rate of shell accretion was reduced in pesticide exposed bivalves than in normal bivalves. Accreted piece of the shell found to become brittle with dull and poor nacre. Dr. Pramod P.
