Tube fishway technology will get fish up and over those dam walls

The tube fishway has the potential to reconnect fish in rivers to allow them to more freely migrate up and downstream.

Engineers and scientists at UNSW Sydney have come up with an ingenious way to get fish past dam walls, weirs and other barriers blocking their migration in Australian rivers.

The so-called tube fishway is a low-cost and low-energy installation that works by pumping fish at high velocity – protected by a cushion of water – through a tube running over the obstructing barrier to deliver them safely into the water on the other side.

And following a successful demonstration of a prototype recently at the UNSW Water Research Laboratory in Manly Vale, the group is in talks with Parramatta City Council in Sydney about the possibility of installing one at the Marsden St Weir.
