Growth and reproduction of Planorbarius corneus (Linnaeus 1758) in laboratory conditions

This study presents the results of observation on reproduction and growth of Planorbarius corneus over the course of several years of continuous rearing in the laboratory. Some reproduction and growth features which could provide more information for culturing P. corneus in the laboratory were presented. Noticed was a statistically significant negative correlation between initial snail size and growth and positive correlation between size and fecundity. Noticed was also a decreased growth and reproductive output in progeny of isolated animals.
