Giving some mussel muscle to the Peel-Harvey inlet

Thanks to jetty owners throughout the Peel-Harvey estuary near Mandurah, shellfish numbers have taken a boost and are supporting native fish populations in the region.  

The reason behind the growing mussel abundance comes down to a clever initiative called ‘Pimp My Jetty’ – created by Ozfish, and supported by Recfishwest, which involved jetty owners agreeing to host a hanging shellfish habitat such as natural ropes under their private jetty.  

The fibres of the rope provide an ideal surface for mussel larvae and for maturing mussels to grow on. As more mussels create homes on the new hanging habitats, it leads to more mussel spat in the estuary and helps to revive the once thriving shellfish population. 

The mussels also improve water quality through filtering it and provide an increased high-quality food source and better habitats that supports black bream and other native fish species such as tailor, herring, whiting, flathead and others.  

More mussels mean more fish, which is a win-win for recreational fishers and the water quality of the estuary. 

The naturally occurring fibres from ropes (pictured left) create an ideal surface for mussels to latch on to, leading to an abundance of shellfish (pictured right) and fish species over time.

Steve Pursell, OzFish Program Manager for WA, believes the success of this year’s project underlines what can be achieved when recreational fishers, local communities, and scientists work together.  

“We have been pleased by the numbers of private jetty owners who came forward to be involved – it shows they understand the importance of healthy habitats in our waterways,” he said.  

“Not only do mussels play a key role in filtering and improving the water quality, research shows they once made up 64 per cent of black bream’s diet in the area but that is now as low as 19 per cent. By restoring habitat, our volunteers are helping to create better fishing,” said Steve.  

Recfishwest Operations Manager Leyland Campbell said, “Estuaries such as those located in the Peel-Harvey region are crucial for providing easy access to great fishing spots and as nursery habitats for key recreational species.  

“Thanks to initiatives like Pimp My Jetty, we not only help restore a valuable food source for fish like black bream, tailor and others, but it also helps improve the water quality and directly benefits the fishing action in the area. 

“The Mandurah estuary is an incredibly unique angling destination for crabbing and yellowfin whiting fishing on surface lures and poppers during the warmer months. Fishers can feel comfortable knowing these kinds of projects will improve these crucial fishing experiences over time.  

“Thanks to all the friendly Peel-Harvey locals who own a jetty and their collaboration with Ozfish, they are helping breathe more life into our estuaries.”  

The Harvey-Peel Estuary in Mandurah has been a much-loved fishing spot for generations and the Pimp My Jetty initiative from Ozfish will help anglers such as Harry Tropiano (pictured right) catch more black bream and other species.

The Pimp My Jetty project is funded by Recfishwest, Navico, the Western Australian Government’s Royalties for Regions program, and BCF – Boating, Camping, Fishing. It is supported by Peel Harvey Catchment Council.

Help sew the seeds for a healthier future for Cockburn Sound

Recfishwest is encouraging metro fishers to get involved and back in Ozfish’s latest Seeds for Snapper drive – its program to help restore critical seagrass habitat in Cockburn Sound.

Since 2018, Recfishwest has collaborated with OzFish and the University of Western Australia to restore seagrass meadows in Cockburn Sound, which are vital as a nursery ground for countless fish and species of marine life including pink snapper, King George whiting, herring, Western rock lobster, prawns, squid and blue swimmer crabs.

Now in it’s fifth year, Seeds for Snapper has already helped collect more than one million seeds in Cockburn Sound, but as volunteers are the driving force behind this project, Recfishwest is encouraging everyone to dig deep and help out by collecting the seeds or dispersing them.

The Seeds for Snapper program relies on community support from recreational anglers, divers, businesses and residents to help disperse the seeds, which are the key to helping rejuvenate juvenile fish habitats.

It is estimated that a single hectare of restored seagrass produces on average 207 kilograms of fish per year and stores 35 times more carbon than the same equivalent area of rainforest.

Over the last century, 85 per cent of these crucial seagrass meadows – equivalent to nearly 2,000 Optus Stadium-sized ovals – have been lost in Cockburn Sound.

With the Government recently proposing a shock eight to nine-month west coast demersal species ban per year and with the Government’s plans to build a new port in Cockburn Sound starting in 2027, the Seeds for Snapper program underpins why preserving the sustainability of these seagrass meadows is more important than ever.

“Cockburn Sounds seagrass meadows act as a nursery area for important species such as crabs, snapper, squid, whiting and garfish and supports the only known spawning aggregations of pink snapper in the West Coast Bioregion, said Recfishwest CEO Dr Andrew Rowland.

“Merely maintaining the status quo is not an option after the huge loss of seagrass habitat in the Sound over the years. It is vital, therefore, that initiatives like this are supported and boosted to help improve the environmental state of Cockburn Sound.

“The Sound’s protected waters on the doorstep of our capital city offer great land and boat-based fishing for fishers of all ages and abilities and fishers can play their part to by helping collect and disperse seagrass seeds and breathe more life into these vital nursery grounds.”

There are various ways you can help out with Seeds for Snapper, whether it’s on the shore, on the boats or in the water! Photo courtesy of the OzFish website.

There were more than 350 registered volunteers dedicating their time last year with the Seeds for Snapper program through a variety of roles, including as boat-based netters, qualified scuba and free divers, shore crews and as seagrass seed dispersal units.

The seagrass fruit harvesting and seed dispersal season will take place from November. Collection and dispersal days and times are subject to weather and tides, so if you want to take part in the fifth year of this great program, Recfishwest encourages volunteers to dig deep and register through the link below.

Fishers Want Better Habitat & Better Fishing

What’s your best session fishing for black bream? Can you imagine a session catching over 100 fish, where the bream averaged over 1 kg each…with some up to 2 kg’s?

Local fishers from Albany and surrounds wanting to learn more about why fishing has changed in the area and what can be done to bring back the glory days came down to the Fishers for Fish Habitat Forum held in Albany earlier this month. The forum, which was run by a partnership between Ozfish Unlimited and Recfishwest, provided a unique opportunity for fishers and habitat experts to come together and combine their knowledge to try and work out the key drivers for changes in the quality of local fishing and what could be done to bring back lost fish habitat and better fishing.

The knowledge local fishers have about changes in the quality of fishing in the area provided a rare insight into how big an impact changes in fish habitat have actually had on fishing. An important part of discussions was led by Western Angler editor Scott Coghlan who talked with local veteran Jim Allan and bream young gun Callum Dowell on their perspectives on changes in the area. Both Jim and Callum had noticed significant changes in the quality of fishing and fish habitat over the years. Jim told tales about some epic bream fishing that used to be available around Albany in years gone by including bream that averaged over 1 kg each, with some pushing 2 kg’s while Callum said at its best it wasn’t unusual to catch over 100 fish in a session! Jim suggested that in terms of habitat loss, one of the key changes that had led to a reduction in the quality of fishing was the huge loss of seagrass in Oyster Harbour, while decreases in rainfall were also hurting the system. Callum had noticed similar changes and noted that on some of the flats he fished the sand had changed over the years from being hard and course to soft mud.

It was amazing to see how close the changes seen by fishers matched with what had been seen by the habitat experts, who further discussed how these changes fit in with the changes in fish habitat. Local seagrass expert, Geoff Bastyan, reinforced the changes seen by Jim to seagrass in the harbour and showed how with the right support, it was possible to bring back much of this lost habitat. There was also some great discussion about the import role bringing back oyster reefs will have on the harbour with Black Bream, Skippy and Yakka’s already seen investigating the developing reefs.

Karen McKeogh from the Department of Water also led a great discussion about how modifications to the Torbay lakes meant that a highly productive system went from producing Murray Cod up to 1.3m to now having health warnings. This forum highlighted the importance of sharing the knowledge fishers have about the changes they have seen in their local systems and their eagerness to bring back some of the lost crucial fish habitat, and better fishing. If you know a fish habitat in your local waterway that needs to be restored, talk to locals in your community and get in contact with the Recfishwest Habitat Officer Michael Tropiano to see what can be done in to bring back fish habitat and better fishing.

Everyone at the forum was hugely appreciative of the members of the Albany Boating and Offshore Fishing Club for hosting the event and all their assistance in running the forum and for support for the event from The Nature Conservancy and the Fisheries Research and Development Commission.
