Preventative measures: It is currently legal to own B. chinensis in the United States. Rixon et al. (2005) recommend the erection of trade restrictions regarding the sale, importation or breeding of high-risk species in areas where they have potential for establishing populations. In particular, vectors of invasion such as live fish marks and the aquarium industry should be addressed (Rixon et al., 2005; Strecker et al., 2011). It does not feed on macrophytes, making it popular with aquarists and water gardeners.
B. chinensis is thought to be spread overland by attachment to macrophytes on boat hulls. Changing human behaviour such as encouraging removal of macrophytes may reduce the spread of this snail, as well as other invasive species of concern (Havel, 2010).
Chemical control: Copper sulfate is approved by the U.S. Environmental Protection Agency as a snailicide commonly used for control of other invasive snail species. It has recently been used for the first time against B. chinensis in Jackson County, Oregon. While 100% eradication has not been achieved, it may be a successful method for controlling populations (Freeman, 2010).
Location Specific Management Information
Copper sulfate is an EPA approved snailicide that has been used in Jackson County, Oregon to control B. chinensis. While 100% eradication has not been achieved, it may be a successful method for controlling populations (Freeman, 2010).
The Oregon Fish and Wildlife Commission is likely to add B. chinensis to the list of organisms that it is illegal to possess or sell in the state (Freeman, 2010).
Bellamya chinensis is listed in the 1998 State of Washington Aquatic Nuisance Species (ANS) Plan, which was updated in 2001 (US Fish and Wildlife Service, 2010).
