Grey literature, which includes policy reports, technical guidelines and dissertations and theses, is produced by many actors within aquatic sciences, fisheries and aquaculture. Many hours of research go into producing these documents, often with the purpose of solving particular environmental, species or socio-economic problems. Whilst the nature of the problem tackled by much grey literature is focused on a specific problem in a specific area, its lessons can often be applied to similar problems or environments around the world. What prevents this taking place is that grey literature can be hard to access – due to the way it is produced and stored, grey literature can often be stored offline, or on institutional websites where it is difficult to access using internet search engines or databases.
