Fisheries Research Reports

Final FRDC Report – Project 2003/005

Objectives:

1. To investigate the implications of the setose and maximum size rules.

2. To undertake preliminary investigations into the implications of egg diameters being significantly smaller at the Abrolhos Islands than at the coast.

3. To quantify the extent of the breeding grounds, so as to weight the overall egg production index for the stock by the contribution of the management zones.

Increases in efficiency due to modern electronic equipment, improved fishing vessels and knowledge about the grounds and lobster behaviour, have all led to western rock lobster fishers becoming more efficient at …

Finfish Aquaculture In Western Australia. Final Esd Management Report For Marine Finfish Aquaculture., Department Of Fisheries Western Australia.

Fisheries Management Papers

It has been recognized that there are a number of potential impediments to achieving continued growth of this industry. These include the need for increased investment, an expansion in markets and ensuring environmental sustainability. One of the most important however, is meeting the growing expectations of the community that all aquaculture sectors can clearly demonstrate that they are operating within the principles of Ecologically Sustainable Development (ESD). Western Australia’s Department of Fisheries is responsible for the management of aquaculture in the State and is committed to implementing ESD. These principles are contained within the objectives of the Fish Resources Management …

Fisheries Research Report No.157 - The Western Rock Lobster Fishery 2003/2004 And 2004/2005, Simon De Lestang, E H. Barker

Fisheries Research Reports

The 2003/2004 season produced the second highest catch recorded to date (13,684 tonnes), up markedly on the previous season’s catch of 11,415 t. Nominal effort in 2003/2004 (10,180,444 pot lifts) did not vary by nearly as much as did the catch, with total pot lifts declining only slightly (<1%) on the previous season. Season 2004/2005 produced a catch of 12, 236 tonnes, down on the previous season’s catch of 13,684 t. Similar to the catch, total nominal effort in 2004/2005 (9,789,671 pot lifts) also declined fairly substantially (4%) on the previous season. Recreational catches for the above two seasons were also down on their respective previous seasons by 52 and 11% each.

Puerulus settlement coast wide during 2003/2004 was below average, especially towards the southern and northern extremes of the fishery (Port Gregory and Jurien Bay south). This was also the case during the following season (2004/2005), although the poor settlement was more evenly spread across the entire fishery. Catch predictions from these …

Fisheries Research Report No. 174 - Spatial Scales Of Exploitation Among Populatons Of Demersal Scalefish : Implications For Management. Part 2: Stock Structure And Biology Of Two Indicator Species, West Australian Dhufish (Glaucosoma Hebraicum) And Pink Snapper (Pagrus Auratus) In The West Coast Bioregion, Department Of Fisheries, Western Australia

Fisheries Research Reports

Final FRDC Report - Project 2003/052

EDITORS: R. Lenanton, J. StJohn, I. Keay, C. Wakefield, G. Jackson, B. Wise and D. Gaughan

West Australian dhufish is endemic to shelf waters of south-western Western Australia (WA). In contrast, snapper (known as “pink snapper” in WA) has a continuous distribution around the southern coastline of mainland Australia and in New Zealand. Dhufish and snapper are the two most important exploited demersal scalefish species in the West Coast Bioregion (WCB) of WA, which extends from Kalbarri (27°S) to Augusta (35°S). This study examined regional variation in the biology of the two species, their …

Fort Richardson Ordnance Detonations And The Harbor Porpoise: A Case Study In Marine Mammal Bioacoustics, Heather Heenehan

Honors Scholar Theses

Hearing is extremely important for cetaceans because it is their “principal sense” (Weilgart, 2007) thus the harbor porpoise and other marine animals are highly dependent on sound for survival. This is why we should care about the impact of noise on animals like the harbor porpoise. Since sound travels so well in water, an explosion, sonar, boat noise, etc. can affect a very large area and thus many different species of marine mammals. Although military actions such as low frequency sonar have made recent news, noise has been affecting cetaceans, especially beaked whales, since at least 1991 (Weilgart, 2007).

Fisheries Research Report No. 191 - Maximising Survival Of Released Undersize West Coast Reef Fish, Rodney C J Lenanton, Jill St John, Brent S. Wise, Ian S. Keay, D J. Gaughan

Fisheries Research Reports

Final FRDC Report – Project 2000/194

In Australia, most fishery managers regulate the catch of recreational fishes using size and bag limits. The effectiveness of these regulations depends on the fish surviving capture and then release back into the water. Effective management of fishing using size or bag limits therefore requires an understanding of the rates of mortality of released fish and what factors are causing mortality so that these might be alleviated. The rates and likely causes of mortality of released WA dhufish (Glaucosoma hebraicum) and snapper (Pagrus auratus), breaksea cod (Epinephelides armatus) and baldchin groper (Choerodon rubescens) off …

Fisheries Research Report No. 184 - Macroscopic And Microscopic Description Of Snapper (Pagrus Auratus) Gonads From Shark Bay, Western Australia, Michael C. Mackie, Gary Jackson, Nadia E. Tapp, Jeffrey V. Norriss, Adrian Thomson

Fisheries Research Reports

Since 1997, research on snapper (Pagrus auratus, Sparidae) in the inner gulfs of Shark Bay has focussed on providing biological information required for the management of the regionally important recreational fishery. A major component of this research has been a comprehensive investigation of snapper reproductive biology to determine size and age at maturity, the timing of the spawning season and to estimate batch fecundity. This research has necessitated a review of the macroscopic staging system used for P. auratus in Western Australian waters and the development of a more detailed microscopic system to allow accurate analyses of histological material. Based …

Fisheries Research Report No. 192 - Determination Of A Cost Effective Methodology For Ongoing Age Monitoring Needed For The Management Of Scalefish Fisheries In Western Australia, Montgomery Craine, Ben Rome, Peter Stephenson, Brent S. Wise, D J. Gaughan, R Lenanton, Richard A. Steckis

Fisheries Research Reports

Final FRDC Report – Project 2004/042

Objectives

1. Determine for the 20 major WA scalefish species (4 - 5 in each bioregion) the relative accuracy of structures used to estimate age (e.g. Sectioned/whole otoliths, lengths, otolith weight, other otolith dimensions or some combination of these).

2. For each stock, examine the relative impact on the calculated age-compositions and their effect on model outputs and conclusions from varying (i) the method of ageing used (only where this is possible from available data) (ii) the number of individuals used in the samples (iii) the spatial distribution of the samples used (iv) if …

Fisheries Research Report No. 189 - Results Of A 2007 Survey Of The Swan River Region For Four Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells

Fisheries Research Reports

A survey of the Swan River region for four non-indigenous marine species was conducted in 2007: the European shore crab Carcinus maenas, the Asian bag mussel Musculista senhousia, the European fan worm Sabella spallanzanii, and the scallop Scaeochlamys livida. The first three of these species are global in their distribution and on the ‘top-ten world’s worst invaders listing; the last species is introduced from the eastern states of Australia.

In this survey divers on SCUBA examined 43 sites for each of the listed species. Despite previous records of Carcinus maenas and Musculista senhousia in this region …

Fisheries Research Report No. 190 - Esd Reporting And Assessment Subprogram: Strategic Planning, Project Management And Adoption - Stage 2, R Fletcher

Fisheries Research Reports

Final FRDC Report – Project Number 2004/006

The second stage of the operation of the ESD Subprogram was successful, but compared to the focus during the first subprogram period, mostly in a consolidation manner rather than from the generation of significant new tools. This was necessary because it takes time to adopt and integrate significant changes to the methods of operation of agencies and industries. The policies must be there before any real activity can occur and we found that for the broader focused, cross fishery/cross sector applications of the framework, agencies were not in a position for much of …

Fisheries Research Contract Report No. 20 - Risk Assessment Of The Record Brook Inter-Basin Water Transfer Scheme To The Aquatic Fauna Of The Donnelly And Warren Rivers, M. De Graaf, D. L. Morgan, S. J. Beatty, C. W. Hugh

Fisheries Research Contract Reports

Report to the Water Corporation of Western Australia

This report describes the fishes and freshwater crayfishes of the Donnelly and Warren River catchments and provides a risk assessment to these fauna of the proposed extraction of water from Record Brook (tributary of the Donnelly River) and subsequent transfer to Scabby Gully Dam (Warren River catchment). The proposed location of the structure in Record Brook is at the gauging station ~1 km upstream from the confluence with the Donnelly River. The project aims to divert peak flows in the winter and spring flow period, transferring around 500 ML each year. The …

Fisheries Research Report No. 188 - Results Of The 2007 Survey Of The Albany Marine Area For Introduced Marine Species, Justin I. Mcdonald, Fred E. Wells, Michael J. Travers

Fisheries Research Reports

A survey of the Albany marine area (King George Sound, Princess Royal Harbour and Oyster Harbour) for introduced marine pest species was conducted in 2007. This survey was trialling the new system of monitoring for introduced marine pests developed by the National Introduced Marine Pests Coordination Group (NIMPCG). This study represents one of the first trials of this system (the first trial commenced in South Australia is still ongoing). In this survey fifty-two of the fifty-five potential pest species were targeted. Three species were excluded on the basis of salinity and/or temperature tolerances being exceeded. A wide variety of sampling …

Fisheries Research Report No. 183 - Development Of A Long-Term Program To Monitor Coastal Communities Within The Swan Region, Lynda M. Bellchambers

Fisheries Research Reports

Marine benthic communities along the metropolitan coast of Western Australia are varied and unique. The southward flowing Leeuwin Current brings warm water and tropical recruits whilst the cooler counter current, the Capes Current, brings the temperate recruits. The result is a mosaic of tropical species intermingled with the dominant temperate species. These areas sustain varied fish and invertebrate communities making this coast a highly desirable location for recreational and commercial use. Management strategies are in place that attempt to maintain the sustainability of this area including various fishery restrictions and the implementation of areas zoned as sanctuary zones (no-take). However, …

Fisheries Research Report No. 185 - Performance Indicators, Biological Reference Points And Decision Rules For Western Australian Abalone Fisheries (Haliotis Sp.): (1) Standardised Catch Per Unit Effort, Anthony M. Hart, Frank Fabris, Nick Caputi

Fisheries Research Reports

This report summarises the performance indicators (PIs) and biological reference points (BRPs) developed from standardised catch per unit effort (SCPUE) models of the Western Australian abalone fisheries. It also outlines analysis and consultation processes used to construct these indicators. Other PIs, such as those relating to harvest rate and recruitment, will be developed when more fishery independent data becomes available.

A comprehensive 7-step process was utilised to develop PIs.

1) The Abalone Management and Advisory Committee (AbMac) considered options and advised that in the short-term, catch and effort trends be reviewed with other potential indicators to be considered at a …

Assessment Of Endocrine And Gonadal Condition Of Male Largemouth Bass From Lake Mead, Nevada, Reynaldo Patino, Steven L. Goodbred, Erik Orsak, Jill A. Jenkins, Michael R. Rosen

Lake Mead Science Symposium

Las Vegas Bay (LVB) of Lake Mead receives combined flows of tertiary treated wastewater effluent, urban runoff, and groundwater from the Las Vegas metropolitan area. This study examined the potential for endocrine disrupting effects of these anthropogenic inputs on male largemouth bass (Micropterus salmoides). Adult male bass were collected at two sites within Lake Mead: Overton Arm (OA, reference site), and Las Vegas Bay (LVB). Post-spawn fish were collected in July 2007 (n = 6-10 per site) and pre-spawn fish in March 2008 (n = 13 per site). Post-spawn fish were characterized by regressed testes whereas pre-spawn bass had full-grown …
