New Zealand fish passage guidelines
Recommended best practice for designing instream structures to provide for fish passage.
Fish passage assessment tool
An app and website to record and assess instream structures and their impact on fish passage. The information is also added to a database that is accessible to the public.
Lessons learnt case studies
These case studies provide examples of fish passage problems and solutions, and show how different approaches were designed and installed. Monitoring results that show how well the modifications worked are also included.
