Table 2 Description of inclusion criteria used by the Review Team when screening articles at the title and abstract level

Relevant subjects

Freshwater ecosystems, including both lakes and rivers that contain non-native fish species

Relevant types of interventions

Article describes the type of eradication method used in an attempt to eradicate a fish species. Eradication method can include: mechanical, chemical, biological, environmental or other

Relevant types of comparators

An external control site: similar waterbodies with no intervention (i.e., waterbodies with non-native fish present but have not had any fish management projects conducted in them), before intervention control site within same waterbody, or an alternative intervention type conducted on the same waterbody

Relevant types of outcomes

Measured effect of treatment. Reported measured effect can be quantitative or observational and generally should indicate some change in abundance of target species relative to before treatment or control

Relevant types of study designs

Given the complexity of eradication projects, all types of study designs will be examined, including but not limited to:

 Before/after (BA)

 Comparator/intervention (CI)

 Before/after/comparator/intervention (BACI)

 Randomized controlled trial (RCT)

Studies that do not do or report any before or after assessments following the implementation of an eradication effort will be excluded from the review (i.e., studies where no data is presented that would allow for any assessment of a change in abundance of the target species following eradication efforts)
