Fisheries Research Report No. 242 - Biology, Stock Status And Management Summaries For Selected Fish Species In South-Western Australia, Claire B. Smallwood
Fisheries Research Reports
ObjectiveMany people are interested in fishes, but often it can be difficult to access reliable information on the biology, status and management of a particular fish species. Although there is a long history of world class fisheries research and management in Australia, the full details are generally only available in a fragmented manner in various scientific journals, books and reports. In some cases, these sources of information can be difficult to find and, even for fisheries researchers and managers, who usually have access to scientific journals, certain types of information such as unpublished reports or student theses, can be hard …

Throughout Western Australia Fisheries and Marine Officers (FMOs) play a vital role in ensuring the sustainability of fish resources. Since July 1998, in the course of their other compliance activities, FMOs have collected information from recreational fishers on their catch and fishing trip. The primary objective of this report was to summarise the data collected by FMOs and ascertain the effectiveness of the convenience (i.e. unstructured) sampling technique for determining trends in recreational fishing patterns throughout Western Australia. Recreational fishing data was collected by FMOs during 6 629 land-based and boat-based patrols completed between 1998/99 – 2009/10, mostly within the …
Identification Of Critical Habitats For Juvenile Dhufish (Glaucosoma Hebraicum) Nrm Project 09038 – Protecting Inshore And Demersal Finfish, Paul D. Lewis, Gabby E. Mitsopoulos, Brett W. Molony
Identification Of Critical Habitats For Juvenile Dhufish (Glaucosoma Hebraicum) Nrm Project 09038 – Protecting Inshore And Demersal Finfish, Paul D. Lewis, Gabby E. Mitsopoulos, Brett W. Molony
Fisheries Research Reports
The Western Australian dhufish (Glaucosoma hebraicum) is an iconic demersal species that is endemic to the lower west and south coasts of Western Australia (WA). Information on the critical habitat and distribution of juvenile dhufish, less than two years of age and ca 150 mm total length (TL), was limited to a single study in one area where they have been previously collected. Increasing the knowledge on the habitat types occupied by juvenile dhufish, the distribution of these habitats in the West Coast Bioregion and methods to potentially monitor the annual recruitment of the species are important in their management.

Status Of The Cockburn Sound Crab Fishery, Danielle Johnston, David Harris, Nick Caputi, Simon De Lestang, Adrian Thomson
Fisheries Research Reports
Blue swimmer crabs (Portunus armatus) (formerly Portunus pelagicus; Lai et al., 2010) in Cockburn Sound, Western Australia, are the basis of an important commercial and recreational fishery close to the Perth metropolitan area with the commercial fishery achieving a peak catch of 362 t in 1997/98 and a recreational catch of about 18 t. Commercial blue swimmer crab catches declined significantly since 2000 due to low stock abundance, resulting in the closure of the fishery in December 2006.

Assessment Of The Risks Associated With The Release Of Abalone Sourced From Abalone Hatcheries For Enhancement Or Marine Grow-Out In The Open Ocean Areas Of Wa, Brian J. Jones, Warrick Fletcher
Fisheries Research Reports
The virus that causes Abalone Viral Ganglioneuritis (AVG) is considered to be exotic to Western Australia (WA). The known distribution includes Victoria, Tasmania and Taiwan. There are a number of known strains of the virus; Tasmanian strains do not (to date) cause mortalities in wild abalone (but do so in farms and processing facilities). Victorian and Taiwanese strains cause high mortalities in wild abalone. Despite active surveillance, the virus has not been found in NSW, South Australia or Western Australia but there is a low likelihood that WA specific strains may exist undetected.

Pilot Evaluation Of The Efficacy Of Electronic Monitoring On A Demersal Gillnet Vessel As An Alternative To Human Observers, R Evans, Brett Molony
Fisheries Research Reports
A large number of documents exist in peer reviewed and ‘grey’ scientific literature that describe ‘how to’ establish a generic observer program for bycatch. Rather than repeat the many reviews of establishing observer programs, this component of WAMSI project 4.4.1 undertook a pilot trial to test the efficacy of using Electronic Monitoring (EM) in place of on-board human observers to record and identify the catch composition of a commercial demersal gillnet vessel. Approximately 80% of all catch (including target, by-product and bycatch species), including interactions with threatened, endangered and protected species (TEPS) could be identified to the same taxon as …

Quantifying Recreational Fishing Catch And Effort: A Pilot Study Of Shore-Based Fishers In The Perth Metropolitan Area, Claire B. Smallwood, K H. Pollock, Brent S. Wise, Norman G. Hall, Daniel J. Gaughan
Fisheries Research Reports
Recreational fishing is a popular activity throughout Western Australia, including adjacent to the populous Perth Metropolitan area. Understanding the level of catch and effort associated with this activity is essential for the sustainable management of fish stocks. Whilst the focus of recent surveys in the Perth Metropolitan area has been on boat-based fishers targeting demersal species, shore-based fishing has not been measured for many years. Recent changes to management controls for these demersal species, including the implementation of a fishing boat licence, may increase existing pressures on nearshore stocks by displacing fishing effort onto these resources. Therefore, a need exists …

Fisheries-Dependent Indicators Of Climate Change In Western Australia Wamsi:Sub-Project 4.2.3, Nick Caputi, Alan Pearce
Fisheries-Dependent Indicators Of Climate Change In Western Australia Wamsi:Sub-Project 4.2.3, Nick Caputi, Alan Pearce
Fisheries Research Reports
The use of fishery-dependent data may be a cost-effective way of assessing whether there have been any changes in the distribution and relative abundance of species. Such indicators are part of an ongoing data gathering system and the costs are relatively low compared to those of a fishery-independent field program. Fishery-dependent data may therefore be obtained at a higher frequency and allow detection of changes faster than would be possible from the results from the direct sampling of specific sites within entire ecosystems.

Evaluation Of The Recreational Marron Fishery Against Environmental Change And Human Interaction: Final Frdc Report – Project No. 2003/027, Martin De Graaf, Stephen Beatty, Brett M. Molony
Fisheries Research Reports
The distribution of marron in the southwest of Australia has seen many changes since European settlement. Reconstructions of their range from historical records suggested that marron inhabited the waters between the Harvey River and Denmark River. Due to translocation, their range has expanded as far north as the Hutt River and as far east as Esperance. Although at present marron still exist in all the original rivers within the southwest, their distribution within these rivers has contracted. Poor water quality, salinity, low rainfall and environmental degradation in the upper and lower reaches have restricted marron populations.
