What is the recommended action for equipment after completing an electrofishing survey?

Cleaning and disinfecting equipment after completing an electrofishing survey is essential for biosecurity. This step helps to prevent the transfer of invasive species and pathogens between water bodies. Equipment can inadvertently carry organisms from one ecosystem to another, potentially disrupting local environments and fish populations.

By properly cleaning and disinfecting, you not only minimize the risk of spreading invasive species but also contribute to the overall health of aquatic ecosystems. This practice aligns with conservation efforts and responsible fieldwork protocols.

While the other options may seem convenient, they do not address the critical need for biosecurity. For instance, simply storing equipment without cleaning it could lead to contamination, and only disinfecting if invasive species are suspected can overlook preventative measures. Using soap and water is a good practice for cleaning, but it may not be sufficient on its own to ensure thorough disinfection against all potential contaminants. Thus, option B provides the most comprehensive strategy for responsible electrofishing practices.
