Studies on life span, growth increments and energy budget of the freshwater snailPila globosa (Swainson) in an artificial pond
Growth rate, instantaneous growth rate and energy budget ofPila globosa in an artificial pond were estimated using marking and recapture method. A decrease in growth rate and instantaneous growth rate were noticed with the increase in body weight. The life span ofP. globosa assessed was more than 4 years. The rates of feeding, absorption and metabolism of different weight-classes have also been studied.
