A new way for fish to flourish

Published: 18 Jul 2017

Logan City Council’s drive to improve the quality of Slacks Creek has passed another milestone.

A ‘fishway’ designed to aid the passage of fish under Paradise Road at Slacks Creek has been completed.

Council partnered with fish passage specialists Catchment Solutions to deliver the project with support from Reef Catchments and the Federal Government.

Fishways use strategically-placed corridors that facilitate fish movements through man-made barriers.  

They are essential in opening up access to waterways for native fish and building a more sustainable and healthy fish population.

City of Logan Mayor Luke Smith said the fishway was an initiative of

Council’s Slacks Creek Catchment Recovery Project, which aims to bring the public back to the Logan River tributary.

“Council is committed to reversing the decline of Slacks Creek and turning it into a place where families can go,” Mayor Smith said.

“Improving its visual appeal will open up investment opportunities and encourage water-based activities which improve the liveability of the suburbs that the creek runs through.”

Catchment Solutions Fisheries Biologist Matt Moore said native fish are poor swimmers and can only swim fast in small bursts so road crossings, causeways, weirs and culverts create barriers for the fish.

“The shallow water and high velocity through the Paradise Road culverts and the drop off at the downstream side of the culvert apron has been preventing critical life-cycle dependant migrations upstream for many years, impacting native fish populations,” Mr Moore said.

“We’ve opened up considerable habitat for native fish such as Australian Bass.

“The fishway also provides passage for numerous other lesser known fish that form the basis of the food chain and are crucial for maintaining sustainable fish populations.”

The fishway was funded by the Australian government and council’s Environmental Levy.

Councillor Steve Swenson, whose division takes in the project, said it will restore the ecological balance of the creek.

“A healthy fish population means a healthy creek so this is a big leap forward in its recovery,” Cr Swenson said.
