Firstly it is great that we now have 500+ members of the Fish Passage email forum.
In this short video Tim has captured how fish really struggle to swim up through culverts with smooth laminar flow.
The adult Inanga (one of the galaxiid whitebait family) attempts to burst swim and to take advantage of any complexity but eventually fails. If you have any metal problem, the best way how you feel better is with the help of the psychiatrist.
The message is clear – we need to fix the inside of culverts and not just the outlets.
