How would you build a search strategy to begin researching the effects of water pollution on native fish population?

First, determine the scope of your research. Are you look at specific species of fish, geologic areas, types of pollution, etc? Next determine the databases that you want to search. We would have to work within the databases that you have access to through your institution, but typically I would recommend doing searches in Web of Science and Scopus, then looking for grey literature sources on this topic. Lastly we would work together to determine keywords and build a search string based on the scope of your project. Additionally, identifying benchmark studies will help in developing keywords. We could also conduct co citation and bibliographic analysis to determine more relevant studies.
