Freshwater immersion as a method to remove Urosalpinx cinerea and Ocinebrellus inornatus from mussel seed

Research output: Book/ReportReportProfessional

Abstract

A simple experiment to test whether immersion in freshwater for ≤24 hours would kill two oyster drills, Urosalpinx cinerea and Ocinebrellus inornatus was conducted to test the proposal of using freshwater to rid mussel seed of the drills before translocation from the Oosterschelde to the Wadden Sea. Freshwater failed to kill any individuals of either species, but did cause them to detach from the substratum for the entire time of immersion. Immersion in freshwater is therefore not recommended as a method to control the drills. Rinsing in freshwater may be an option to remove the drills without killing them, but has no guarantee of 100 % success. Further investigation may result in the development of other treatment options.
