Biofouling assessment protocol for leisure boats and marinas
This protocol has been developed as a part of the COMPLETE-project (Completing management options in the Baltic Sea Region to reduce risk of invasive species introduction by shipping) funded by the Interreg Baltic Sea Region Programme. The aim of this protocol is to identify the potential risk of non-indigenous species (NIS) transfer by leisure boats and trailers in the Baltic Sea region. The sampling methods were tested in Finland during summer 2018, and the final protocol was developed according to the field-testing experience.
