State Of The Fisheries: Status Reports And Aquatic Resources Of Western Australia 2022/23, S.J. Newman, K.G. Santoro, D.J. Gaughan

Status reports of the fisheries and aquatic resources

Aquatic resources within Western Australia (WA) are in good condition, and this has positioned WA as a global leader in sustainable fisheries management. The sustainable fisheries of WA continue to support our strong economy and regional communities. Nonetheless, the lack of a consistent approach to build in the knowledge of Traditional Owners remains a gap in our longer term fisheries science in Western Australia.

Climate change and climate variability continues to impact fish stocks, challenging our ability to effectively monitor, assess, and manage fish stocks. We are continually working with our stakeholders, and the broader community to be adaptive, responsive, …

Recreational Fishing For Western Rock Lobster: Estimates Of Participation, Effort And Catch In 2022/23, Claire B. Smallwood, Karina L. Ryan, Alissa C. Tate, Lucy J. Rudd

Fisheries research reports

The Western Rock Lobster (WRL) (Panulirus cygnus) is the most commonly caught Rock Lobster (RL) species in Western Australia. Catches from the commercial and recreational sectors are required to determine and monitor Total Allowable Commercial Catch (TACC), Total Allowable Recreational Catch (TARC) and proportion of Allowable Harvest Level (AHL) achieved. The TARC is set at 5% of the AHL and evaluated in the harvest strategy based on a 5-year average. Data for the recreational sector are obtained using phone-recall surveys to provide estimates of participation, fishing effort and retained catch (by numbers) from recreational fishers who hold a RL licence. …

Recreational Fishing For Abalone In Western Australia In 2021/22: Estimates Of Participation, Effort And Catch., Claire B. Smallwood, Karina L. Ryan, Eva K.M. Lai, Lucy J. Rudd, Lachlan W. Strain

Fisheries research reports

The Western Australian Recreational Abalone Fishery (RAF) operates in shallow coastal waters along the metropolitan, south-west and south coasts. This hand collection fishery targets three species of abalone. Roe’s Abalone (Haliotis roei) inhabit nearshore reef complexes and are therefore generally collected while wading from the shore in accessible areas. This species is taken from the metropolitan, south-west and south coast regions. Greenlip Abalone (H. laevigata) and Brownlip Abalone (H. conicopora) are collected while wading (including snorkelling) and diving (using compressed air) and occur predominantly in the south coast region.

Recreational fishing for all abalone …

Ecological Risk Assessment For The Western Australian Offshore Crustacean Resource., Jason How, Kimberley A. Smith, Hannah Donnelly, Linda Wiberg, Rebecca Oliver

Fisheries research reports

In December 2022, the Department of Primary Industries and Regional Development (DPIRD) convened an ecological risk assessment (ERA) of the fisheries that access the Offshore Crustacean Resource (Resource).

The Western Australian commercial fisheries that access the Resource are the West Coast Deep Sea Crustacean Managed Fishery, South Coast Crustacean Managed Fishery and West Coast Rock Lobster Managed Fishery. Due to the predominantly offshore distribution of the Resource, there is only minor recreational and customary access of this Resource related to harvesting of southern rock lobster on the south coast.

The ERA considered the potential ecological impacts of harvesting the Resource. …

The ERA considered the potential ecological impacts of the WA commercial Silverlip Pearl Oyster Fishery and related aquaculture activities including hatchery and seeding operations. The assessment evaluated the impact of each activity on all relevant retained and discarded species; threatened, endangered and protected species; habitats and the broader environment. Risks associated with aquaculture activities were also considered, including genetic impacts on …

Developing Novel Remote Camera Approaches To Assess And Monitor The Population Status Of Australian Sea Lions, Mathew Hourston, Daniela Waltrick, Stuart Blight, Ainslie Denham, Alex Hesp, Steve Taylor

Fisheries research reports

This project trialled the use of remote cameras to monitor the relative abundance of Australian sea lions (ASLs, Neophoca cinerea) at three Western Australian (WA) breeding colonies. The research was undertaken by the Department of Primary Industries and Regional Development (DPIRD) to assess whether the analysis of camera footage could be used to estimate ASL relative abundance, providing an alternative to the traditional “boots on the ground” approach (hereon in “BoG”) of visiting colonies to count animals. This report outlines the strengths and limitations of this novel approach rather than providing an update on the population status of ASLs. …

Shore-Based Recreational Fishing In The Perth Metropolitan Area: 2022, Alissa Tate, Lucy Rudd, Claire B. Smallwood

Fisheries research reports

Recreational fishing is a popular activity in Western Australia (WA), occurring throughout the state from boats, and from a variety of natural and man-made structures along the shore. Ongoing monitoring of the shore-based recreational fishery is essential to assist with resource allocation, management evaluation and stock assessments for nearshore species. Especially for species such as Australian Herring and Southern Garfish which had management changes including a reduction in bag limit from 30 to 12 in 2015 and closure of Perth Metropolitan waters in 2017, respectively. An on-site roving creel survey to collect effort and catch data from shore fishers has …

Oestrogenic Subterranean Clover Guide. Identification And Remediation, Kevin J. Foster, Megan H. Ryan, Daniel R. Kidd

Bulletins 4000 -

Subterranean clover (subclover, Trifolium subterraneum L.) is an annual pasture legume that provides high quality feed for livestock. It is estimated to be sown over 30 million hectares across southern Australia, with cultivars developed for the low, medium and high rainfall zones. Unfortunately, some older cultivars contain high levels of phytoestrogen which can affect the reproductive system of sheep and cause other health issues. This became a significant issue for sheep producers from the 1940s as new land was cleared and sheep grazed subclover-dominant pastures. There was a collection of livestock issues observed and these were grouped together under the …

South-West Estuarine And Nearshore Finfish Resource Part 1: Sea Mullet And Yellowfin Whiting, Rodney Duffy Dr., David Harris, Emily Fisher, Kim Smith, Danielle Johnston, Ainslie Denham, Alex Hesp, Blaine Hodgson, Amber Quinn, Marcus Newman

Fisheries research reports

This report focuses on one of the primary target species for which biomass-based stock assessments are periodically undertaken - sea mullet (Mugil cephalus). The report also includes a recent stock assessment for yellowfin whiting (Sillago schomburgkii) due to concerns regarding substantial increases in catch relative to historic levels.

Status of stock(s)

Sea mullet

The current stock level is considered to be acceptable, and the current level of fishing mortality is unlikely to deplete the stock to a level at which recruitment could be impaired. On the basis of the evidence provided, the sea mullet stock in …

The Sheep and Goat Industry Funding Scheme (IFS) has been operating since 2010 to address biosecurity threats relevant to the Western Australian (WA) sheep and goat industry. The Scheme was established by regulation under the Biosecurity and Agriculture Management Act 2007 to enable sheep and goat producers to identify pest and disease priorities at a whole-of-industry level and raise funds for activities to address these priorities.

There are currently three Industry Funding Schemes in operation. In addition to the Sheep and Goat IFS, there is a Cattle IFS and a Grains, Seeds and Hay IFS. The three IFSs operate in …
