Thermal Effect on the Life-cycle Parameters of the Medically Important Freshwater Snail Species Lymnaea (Radix) luteola (Lamarck)


The snails Lymnaea (Radix) luteola exhibited marked variations in growth, longevity, and attaining sexual maturity at different temperatures and diets. At 10°C, irrespective of foods, pH and salinity of water, the snails had minimum life span, maximum death rate and lowest growth rate. At 15°C, the growth rate was comparatively higher and the snails… (More)
