Abstract

Invasive species of snail, Potamopyrgus antipodarum (Gray, 1843), is native species of New Zealand. It feeds on periphyton, diatoms, and plant and animal detritus. It is spread all over the world where negatively affects biodiversity and causes great economic damages. Females which are parthenogenetic are dominating in populations which may reach a number of 800 000snails/m². Species is in competition for food and area with native species which are directly endangered. Adaptations such as tolerance on wide range of temperatures, great depth and high salinity gives it advantage over native species. If it comes to establishing stable populations, species is impossible to eliminate. Therefore the preventive measures such as chemical treatment, drying (water-drainage), heating, freezing and washing equipment, which was previously used on areas where P. antipodarum habits, are very important. In addition, education about ways of spreading these species and control methods is very important.
