    Restoring fish passage

    The movements of many juvenile native fish are often hindered by barriers to fish passage such as dams, weirs, falls, tide gates, culverts, screens and high water velocities. The New Zealand Fish Passage Guidelines sets out recommended practice for the design of instream infrastructure to provide for fish passage.
