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.

Creating seagrass pastures anew for Cockburn Sound

Last weekend, recfishing families joined Ozfish Unlimited at the Cockburn Power Boats Association to take part in an exciting seagrass restoration project called ‘Seeds for Snapper’.

The project aims to reseed Cockburn Sounds Seagrass meadows which support a wide variety of important fish species including whiting, pink snapper, garfish, calamari and blue swimmer crabs.

Cockburn Sound hosts the largest pink snapper spawning aggregations in the West Coast Bioregion.

Fishers and divers helped with all elements of the project from the seagrass ‘fruit’ (seeds) collection, placing seeds in tanks with circulating seawater to separate the seed and dispersing of the seed in predetermined locations within Cockburn Sound. It is hoped that one million seeds can be processed, potentially restoring 10,000 m2 (1 Ha) of lost seagrass habitat per annum for the next three years.

The Seeds for Snapper Family Seeding Day builds on last year’s Seeds for Snapper project which saw approximately 200,000 Posidonia australis seeds collected and dispersed over three trial-seeding sites.

Three months after last year’s seeding activities, establishment and survival of the seagrass seedlings ranged between 6.5 per cent and 20 per cent, which is far better than what has been achieved in the past in attempting to establish new Posidonia australis seagrass meadows.

Below you can see the comparison on two dispersal sites.

Recent research has demonstrated that direct seeding into areas of lost seagrass is likely to be the most cost effective method that may one day be scaled-up to make the biggest long-term difference. Read about it here.

Cockburn Sounds Seagrass meadows  support a wide variety of important fish including squid.

The WA community have a close affiliation with Cockburn Sound, with plenty of good work done previously to protect pink snapper stocks, including pushing for an extension to the annual pink snapper seasonal closure in Cockburn Sound and Warnbro Sound and our famous Snapper Guardians initiative.

The recfishing community greatly values the Cockburn Sound fishery and it’s great to see recfishers once again stepping up to look after the fish habitats that underpin our great fishing experiences.

Cockburn Sound hosts the largest pink snapper spawning aggregations in the West Coast Bioregion.

The seagrass meadows of Cockburn Sound are well recognised as critical foraging and nursery grounds for pink snapper and other fish, mollusc and crustacean species.

Cockburn Sound’s seagrass meadows have declined by nearly 80 per cent from 4000ha in the 1960’s to less than 1,000ha today.

That’s an area equivalent to 1,840 Optus Stadium football fields of seagrass habitat that has been lost in only a few decades. Important species affected by the seagrass loss include not only pink snapper, but others such as squid, garfish and blue swimmer crabs.

Appreciation of the role seagrass meadows play in providing great fishing opportunities is growing in WA due to increased understanding of the critical link between our seagrass habitats and coastal fisheries.
