Catch!Issue #68 June 2022 Recreational fishing newsNew rules for Camden Sound and Horizontal FallsNew fishing rules within Lalang-garram / Camden Sound and Lalang-garram / Horizonal Falls marine parks came into effect on 11 June, 2022. The two marine parks include three different zone types - general use, special purposes and sanctuary. Horizontal Falls includes: Camden Sound includes: There will be new fishing rules within these marine park areas, so it is important to know your zones and where you can and can't fish: 12th WA fishery certified by MSCWestern Australia now has 12 fisheries that meet the world’s gold standard in sustainability! Rare Foods Australia (RFA) recently secured an eco-tick of approval from the Marine Stewardship Council for their ‘hatch and catch’ fishery for greenlip abalone. This new tick of approval highlights our commitment to protecting our State’s marine environment, in a year when we are also celebrating WA’s 10 years of commitment to sustainability through the MSC certification program. BEN signs go fully metroWith City of Stirling finishing up the install of their Beach Emergency Numbers (BEN) signs in early June, it means all metro local government areas now have BEN signage. The number of BEN signs around Western Australia keeps growing, with nearly 1500 now installed around WA, both metro and regional. Named in honour of fatal shark bite victim Ben Gerring, BEN signs aim to improve emergency response times by providing specific location information, vital when emergency services are deployed in the event of a shark sighting, incident or other beach emergencies. Download the SharkSmart WA app to find your nearest BEN sign, weather information and notifications of shark activity.

Keep aquarium fish out of our waterwaysIf you have ornamental fish you no longer want, please don’t release them into our waterways. Ornamental fish that come from an aquarium or get moved from one waterbody to another can have a devastating impact on our native species and aquatic environment. If they get established they can be difficult if not impossible to eradicate and their impact may be irreversible. This is particularly important for high conservation areas such the cave karst system in the Cape Range Peninsular near Exmouth, where DPIRD officers were recently involved in eradicating ornamental fish species. These systems are home to rare cave-dwelling species found nowhere else on earth. Having evolved in isolation, these creatures are particularly vulnerable to introduced species. If feral aquarium fish become established in Cape Range’s waterways, their long-term survival may be threatened. If you no longer want your fish, give them to a pet shop, contact an organisation or find someone willing to take them, and only tip aquarium water on grass, not in drains or waterways. To find out more, check our new Don’t dump that fish brochure, or the aquatic biosecurity pages on our website. Let us know about any unusual fish or pest species you see, or catch, and help us protect WA’s aquatic environment by emailing Aquatic.Biosecurity@dpird.wa.gov.au, or calling FishWatch 1800 815 507. If you do catch a pest or ornamental species, please do not return it to the water.
Tag-recapture lobster studyMore than 60,000 tagged lobsters have been released in our latest scientific study, part of a tag-recapture survey which runs over four years. Studying the returned tagged lobsters helps our scientists understand how the lobster population changes, how fast they grow, and where they migrate to. This research was key to understanding lobster stocks after the Western Rock Lobster fishery moved to quotas in 2010, causing fishers to change their fishing behaviour. The results show that the West Coast Rock Lobster Fishery is in a very sustainable condition and is being fished at a rate below the MEY (Maximum Economic Yield). This matches the current stock assessment models for this species,
and supports the current assessment and management of this important marine resource. Post-release mortalityFishing mortality in a fish stock is determined by the catch that is kept and the proportion of fish that die following release. When fishing mortality is too high, the population can’t replenish itself quick enough and stock size will decline. Post-release mortality rates can be an important factor to consider when monitoring the health of a fish stock, particularly for demersal scalefish, which are highly likely to die after being released. Only one in 10 baldies survive, with dhufish only having a 50/50 chance of survival and pink snapper a one in four chance of survival. The main reasons for post-release mortality are: barotrauma (damage to the internal organs due to being brought up from deep water); shark depredation; too long out of the water; or injury. So what we can do to improve their odds of survival?
Otolith catalogue a WA firstAfter 10 years, and thousands of photos of otoliths from as many species of fish from WA’s South West as possible, a fisheries researcher has produced WA’s first photographic catalogue which showcases 268 different species identified by their otoliths. Otoliths or ‘ear bones’ are small bone-like structures made of a hard calcium carbonate matrix found in a fish’s inner ear, used by the fish for balance and hearing. Being bone, they are often the last parts remaining after the fish has been eaten, digested or decomposed. In addition to being used to age and size fish, another useful feature of otoliths is that each species has their own unique otolith shape, making fish identifiable from just these tiny bones. Check out some of the weird and wonderful shapes! Artificial reef is king at ExmouthWhat a difference just four years can make… these before and after photos show the stunning transformation of an artificial reef deployed off Exmouth in 2018. It is exciting to see how artificial reefs around WA are developing into flourishing productive fish habitats and great fishing sites. King Reef is the fastest growing artificial reef in Australia and is made up of almost 50 concrete modules and six large, repurposed steel structures. It is now home to more than 100 species of colourful fish and coral, highlighting the biodiversity of the Exmouth Gulf. Covering an area equal to five footy ovals’ worth of previously barren ocean floor, King Reef is 6km offshore from town, easily reached by small boats launched from the town boat ramp, providing the community with enhanced fishing experiences. The project is a collaboration between the Exmouth community, Recfishwest, Curtin University, Subcon, BHP, National Energy Resources Australia (NERA) and WA State Government through the Recreational Fishing Initiatives Fund. If you are heading out to wet a line, make sure you stick to the rules and take only what you need for a feed. For more recreational fishing rules, visit fish.wa.gov.au/recfishing. MSC stewardship grants to WA researchersTwo DPIRD research projects have been granted international funding to support the ongoing sustainability of WA’s fisheries. The grants, awarded by the Marine Stewardship Council (MSC) from its Ocean Stewardship Fund (OSF), will be used to collect the habitat data needed to better manage fishing impacts in WA’s Peel Harvey blue swimmer crab and West Coast crystal crab fisheries. These fisheries are MSC certified, meaning their operations and management have been assessed and certified against the highest sustainability standard in the world. The OSF grants will ensure these fisheries can continue to operate at this standard. This year marks 10 years of the WA Government’s commitment to the MSC certification program, which has raised and certified the sustainability standards of 11 fisheries in WA. These OSF funded projects reflect DPIRD’s ongoing commitment to the program. The projects will fund aerial and on-ground surveys of endangered birds in the Mandurah wetlands, and the development of an automated and illuminated underwater camera monitoring system for deep sea data collection off our west coast. Shark depredation studiesShark depredation (or bite-offs) occur when a shark partially or completely eats a fisher’s catch before it can be brought on deck. Recreational, charter and commercial fishers in WA are reporting significant increases in shark depredation, particularly in the Gascoyne and Pilbara. Our researchers have participated in a number of studies to better understand and address shark depredation. Some recent findings include:
Developing measures against shark bite-offs is complex, and there is no easy solution. Check out our shark depredation science update to find out more. SnippetsSeasonal notes
In the courts Breaching the 10kg finfish limit cost a Melville man more than $4600 in the Shark Bay magistrate’s court recently when he was found to have 19.6kgs of finfish fillets at his campsite. The abuse and obstruction of fisheries officers at Lighthouse Bay near the Ningaloo Marine Park in April led to a Great Southern man receiving fines and costs of nearly $3000. Illegal mud crab fishing cost a 47 year old man almost $4000 in fines, penalties and costs in the Derby Court after his boat was found with undersized crabs and 10 more than the personal daily bag limit. Illegal sales of rock lobster, as well as using excess pots and interfering with other people’s fishing gear, has cost a Cooloongup man more than $30 000 in fines and costs, as well as having to forfeit his boat and gear.
