The effect of water temperature and salinity on the longevity of cercaria of marine littoral trematodes Podocotyle atomon (Opecoelidae) and Renicola thaidus (renicolidae)

The influence of temperature and salinity on the survival of free-living cercariae of the marine trematodes Podocotyle atomon and Renicola thaidus has been examined. It was found out, that the survival of free-living cercariae depend upon the temperature and salinity of the water.
