Hi everyone
Below is a YouTube link to a video sent to us from Greg Wallis in Australia.
It shows common galaxiid/inanga (Galaxias maculatus) trying to navigate a vertical wall at a large box culvert.
Despite these fish showing amazing burst-swimming abilities to scale parts of the vertical wall, very few were successful.
Sadly (for the fish), many were picked off by an opportunistic heron.
Simple solutions such as baffles and ramps could vastly improve fish
passage at this culvert.
Enjoy
