Assessing The Ecological Impact Of The Western Rock Lobster Fishery In Fished And Unfished Areas Final Frdc Report – Project 2008/013, Lynda B. Bellchambers, Matthew B. Pember
Fisheries research reports
This project, in consultation with an industry working group, has been instrumental in establishing a closed area in the western rock lobster fishery to assess the potential ecosystem effects of removing lobster biomass from deep water (40-100 m). The major outcome of this research is an improved understanding of the ecosystem that supports the western rock lobster. These types of information for improve the Department of Fisheries’ ability to manage the fishery in an ecosystem based manner and provide scientifically defensible data to more precisely assess the level of risk of the fishery to deep water communities. In early 2013, …

A Likelihood Analysis Of The Introduction Of Marine Pests To Western Australian Ports Via Commercial Vessels, Samantha Bridgwood, Justin I. Mcdonald
Fisheries research reports
The following document is an analysis of the likelihood of an introduced marine pest (IMP) being translocated by commercial vessels into Western Australian (WA) state waters. This analysis is presented at the bioregional level (North Coast, Gascoyne Coast, West Coast and South Coast bioregions) and at the port level. The ports include: Albany, Broome, Bunbury, Dampier, Esperance, Fremantle, Geraldton, Port Hedland, Useless Loop and Wyndham. The analyses are based on vessel data supplied by the ports for the period of 2011. As such, all outputs and assumptions are based on data from that period and while the likelihood may change …

Status Of Demersal Finfish Stocks On The West Coast Of Australia, David V. Fairclough, Brett W. Molony, Brett M. Crisafulli, Ian S. Keay, Sybrand Alexander Hesp, Ross J. Marriott
Fisheries research reports
Assessments of the key indicator species for the West Coast Demersal Scalefish Resource (WCDSR; West Australian dhufish Glaucosoma hebraicum, Snapper Pagrus auratus and Baldchin groper Choerodon rubescens) in 2007 and 2009 demonstrated that the stocks were experiencing overfishing. Thus, between late 2007 and early 2010, substantial changes were made to the management of the commercial and recreational fisheries that exploit the WCDSR. These were designed to reduce catches of the entire suite of demersal scalefish species (and of each indicator species) by both the commercial and recreational sectors in the West Coast Bioregion (WCB) by at least 50 % of …
Identifying Factors Affecting The Low Western Rock Lobster Puerulus Settlement In Recent Years Final Frdc Report – Project 2009/18, Nick Caputi, Ming Feng, Simon De Lestang, Ainslie Maree Denham, James D. Penn, Dirk Slawinski, Alan Pearce, Evan Weller, Jason R. How

Potential Eradication And Control Methods For The Management Of The Ascidian Didemnum Perlucidum In Western Australia, Julieta Muñoz, Justin I. Mcdonald
Potential Eradication And Control Methods For The Management Of The Ascidian Didemnum Perlucidum In Western Australia, Julieta Muñoz, Justin I. Mcdonald
Fisheries research reports
In Western Australia, the invasive colonial ascidian Didemnum perlucidum was first detected in the Swan River Estuary in 2010 and subsequently recorded at multiple locations across the State. Ongoing research by the Department of Fisheries (the Department) indicates that this species exhibits strong seasonal changes in abundance. Although, D. perlucidum is able to reproduce sexually (larvae) and asexually (budding) year round, larvae density and settlement, and overall colony size significantly decreases during the colder months (winter). From a management point of view this period would present the best opportunity for an attempt at eradication or control of this species.
Independent Observations Of Catches And Subsurface Mitigation Efficiencies Of Modified Trawl Nets For Endangered, Threatened And Protected Megafauna Bycatch In The Pilbara Fish Trawl Fishery, Corey B. Wakefield, Stuart Blight, Adrian W. Thomson, Clinton Syers, Shane O'Donoghue
Independent Observations Of Catches And Subsurface Mitigation Efficiencies Of Modified Trawl Nets For Endangered, Threatened And Protected Megafauna Bycatch In The Pilbara Fish Trawl Fishery, Corey B. Wakefield, Stuart Blight, Adrian W. Thomson, Clinton Syers, Shane O'Donoghue
Fisheries research reports
Mitigation of endangered, threatened and protected (ETP) species is a challenge in many commercial fisheries globally and independent observer programs are often implemented to determine accurate estimates of interaction rates. However, interactions with ETP species may be extremely rare requiring very high and therefore costly levels of observer coverage to provide adequate statistical rigor for such programs.
The Marine Heat Wave Off Western Australia During The Summer Of 2010/11 – 2 Years On, Nick Caputi, Gary Jackson, Alan Pearce
The Marine Heat Wave Off Western Australia During The Summer Of 2010/11 – 2 Years On, Nick Caputi, Gary Jackson, Alan Pearce
Fisheries research reports
This second workshop on the ‘Marine heat wave - 2 years on’ was held on 11 March 2013 about two years after the original event in the summer of 2010/11. The first workshop focused on the oceanographic conditions associated with the event as well as the short-term effects such as fish kill and southerly range extension of a number of tropical fish species. The second workshop concentrated on the oceanographic conditions since the workshop and the longer-term (2 years) effect on fisheries and the marine environment.

Biological Synopsis Of Australian Herring (Arripis Georgianus), Kimberley A. Smith, Joshua Brown
Fisheries research reports
Arripis georgianus (‘Australian herring’) is targeted by commercial and recreational fishers in Western Australia (WA) and South Australia (SA). Historically, A. georgianus has been the most commonly retained species of finfish taken by shore- and boat-based recreational fishers in the West Coast Bioregion (WCB) and South Coast Bioregion (SCB) (Smith et al. 2013a) (Fig. 1). The species is harvested by several commercial fisheries which use shore-based netting methods (beach seine, haul and gill nets). Historically, the vast majority of the commercial fishery catch has been taken by the herring ‘trap net’ fishery which operates on various beaches near Albany (SCB).

Status Of The Blue Swimmer Crab Fishery In Shark Bay, Western Australia Fishery Assessment Document, David Harris, Danielle Johnston, Errol Sporer, Mervi Kangas, Felipe Nieves, Nick Caputi
Fisheries research reports
The Shark Bay Crab Fishery on the central coast of Western Australia has developed rapidly in the last 10 years to become Australia’s highest producing blue swimmer crab fishery, with peak landings in 2010 of 828t valued at over AU$6 million. The resource is harvested commercially by the Shark Bay crab trap and Shark Bay prawn trawl fisheries, with negligible amounts retained by the Shark Bay scallop fishery. There are currently five 300-trap licences and 28 trawl (18 prawn and 10 scallop) licences authorized to take blue swimmer crabs in Shark Bay.
