Growth Of A Deep-Water, Predatory Fish Is Influenced By The Productivity Of A Boundary Current System, Hoang Minh Nguyen, Adam N. Rountrey, Jessica J. Meeuwig, Peter G. Coulson, Ming Feng, Stephen J. Newman, Anya M. Waite, Corey B. Wakefield, Mark G. Meekan

Fisheries Research Articles

The effects of climate change on predatory fishes in deep shelf areas are difficult to predict because complex processes may govern food availability and temperature at depth. We characterised the net impact of recent environmental changes on hapuku (Polyprion oxygeneios), an apex predator found in continental slope habitats (>200 m depth) by using dendrochronology techniques to develop a multi-decadal record of growth from otoliths. Fish were sampled off temperate south-western Australia, a region strongly influenced by the Leeuwin Current, a poleward-flowing, eastern boundary current. The common variance among individual growth records was relatively low (3.4%), but the …

Fisheries Management Paper No.266 - Exmouth Gulf Prawn Managed Fishery Bycatch Action Plan 2014-2019. Version 1.0, Department Of Fisheries, Western Australia

Fisheries Management Papers

Bycatch is described as the part of the catch which is returned to the sea (usually referred to as non-retained or discarded) either because it has no commercial value or because legislative requirements preclude it being retained. Thus, this Bycatch Action Plan (BAP) includes unmarketable finfish and invertebrate species, along with endangered, threatened and protected (ETP) species, such as marine mammals, reptiles and some elasmobranchs.

It is Government policy to minimise bycatch in all commercial fisheries. This BAP details a program of actions to address bycatch issues in the Exmouth Gulf Prawn Managed Fishery (EGPMF), in accordance with the EGPMF …

Fisheries Management Paper No.265 - Exmouth Gulf Prawn Managed Fishery Harvest Strategy 2014 - 2019 Version 1.0, Department Of Fisheries Western Australia

Fisheries Management Papers

This fishery-specific harvest strategy has been developed in line with the Department of Fisheries' (Department) over-arching Harvest Strategy Policy for Aquatic Resources (Department of Fisheries in prep.) and in consultation with licensees. The broad scope of the Harvest Strategy Policy for Aquatic Resources is consistent with the National Harvest Strategy Guidelines but as well as considering all retained target species, it also incorporates retained non-target species, bycatch' and other ecological components to ensure the risks to these elements are managed effectively.

The Exmouth Gulf Prawn Managed Fishery (EGPMF) harvest strategy outlines the longand short-term fishery-specific management objectives; a description of …

This paper also provides an overview of the determination in regard to the sectoral allocations of the demersal scalefish resource in the WCB.

Growth Of Tropical Dasyatid Rays Estimated Using A Multi-Analytical Approach, Owen R. O'Shea, Matias Braccini, Rory Mcauley, Conrad W. Speed, Mark G. Meekan

Fisheries Research Articles

We studied the age and growth of four sympatric stingrays: reticulate whipray, Himanutra uarnak (n=19); blue mask, Neotrygon kuhlii (n=34); cowtail, Pastinachus atrus (n=32) and blue-spotted fantail, Taeniura lymma (n=40) rays at Ningaloo Reef, a fringing coral reef on the north-western coast of western Australia. Age estimates derived from band counts within sectioned vertebrae ranged between 1 and 27 years (H. uarnak, 1 - 25 yrs.; N. kuhlii, 1.5 - 13 yrs.; P. atrus, 1 - 27 yrs. and T. lymma, 1 -11 yrs.). Due to limitations of sample sizes, we combined several analytical methods …

James’S Rule And Causes And Consequences Of A Latitudinal Cline In The Demography Of John’S Snapper (Lutjanus Johnii) In Coastal Waters Of Australia, Mike Cappo, Ross J. Marriott, Stephen J. Newman

Fisheries Research Articles

Demographic parameters were derived from sectioned otoliths of John’s Snapper (Lutjanus johnii) from 4 regions across 9° of latitude and 23° of longitude in northern Australia. Latitudinal variation in size and growth rates of this species greatly exceeded longitudinal variation. Populations of John’s Snapper farthest from the equator had the largest body sizes, in line with James’s rule, and the fastest growth rates, contrary to the temperature size rule for ectotherms. A maximum age of 28.6 years, nearly 3 times previous estimates, was recorded and the largest individual was 990 mm in fork length. Females grew to a larger mean …

Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia.

Fisheries Management Papers

The practice of releasing hatchery-reared fish into existing populations to augment fishing (stock enhancement) or restore depleted spawning biomass (restocking) has occurred around the world for decades with varying degrees of success. The underpinning concept is to produce and release fish into wild populations to increase their abundance, catch rates and/or fishery yields

If restocking and stock enhancement activities are to be successful, they should have clear objectives and be well planned and targeted at situations where there is a reasonable expectation of having a beneficial effect.

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia

Fisheries Management Papers

The Department of Fisheries (Department) is proposing a new simplified management approach which focuses on fishing as the core criteria in the new licensing framework. Given the low level of impact of aquatic eco-tours and shore-based fishing, consideration is being given to removing the need for these activities to be formally licensed. The Department is of the view that these activities can be adequately managed by regulations that have broader application across the community.

The current management, licensing and fee structures are complex and provide limited business flexibility. A simplified management approach will also improve the Department’s capacity to monitor …

Draft Management Plan For The West Coast Rock Lobster Managed Fishery., Department Of Fisheries Western Australia

Fisheries Management Papers

West Coast Rock Lobster Managed Fishery licensees target the western rock lobster, Panulirus Cygnus using baited pots (traps) on the west coast of Western Australia (WA). The fishery, which has long been one of the most valuable single species fisheries in Australia, extends from North West Cape to Cape Leeuwin in the south, with the main fishing occurring between Shark Bay and Perth.

In response to a series of poor puerulus settlements commencing in 2009, a suite of management changes have been introduced to significantly reduce catch levels to appropriately deal with the expected low levels of recruitment entering the …

High Connectivity In The Deepwater Snapper Pristipomoides Filamentosus (Lutjanidae) Across The Indo-Pacific With Isolation Of The Hawaiian Archipelago, Michelle R. Gaither, Shelley A. Jones, Christopher Kelley, Stephen J. Newman, Laurie Sorenson, Brian W. Bowen

Fisheries Research Articles

In the tropical Indo-Pacific, most phylogeographic studies have focused on the shallow-water taxa that inhabit reefs to approximately 30 m depth. Little is known about the large predatory fishes, primarily snappers (subfamily Etelinae) and groupers (subfamily Epinephelinae) that occur at 100–400 m. These long-lived, slow-growing species support fisheries across the Indo-Pacific, yet no comprehensive genetic surveys within this group have been conducted. Here we contribute the first range-wide survey of a deepwater Indo-Pacific snapper, Pristipomoides filamentosus, with special focus on Hawai'i. We applied mtDNA cytochrome b and 11 microsatellite loci to 26 samples (N = 1,222) collected across …

Fisheries Occasional Publication No.99 - Review Of The Western Australian Rock Lobster Stock Assessment, Andre E. Punt, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In 2000, the West Australian Rock Lobster (WRL) fishery became the first fishery in the world to be certified by the Marine Stewardship Council (MSC). At the annual audit in December 2010, the MSC’s independent certifying body, Scientific Certification Systems, set a number of conditions for ongoing certification. The most important condition under Principle 1, Stock Assessment, was to have an international stock assessment and modelling expert undertake a review of the latest version of the WRL Stock Assessment Report that has been used to provide advice for the management of the fishery, and 2010 stock assessment and 2010/11 management …

Phylogeography Of The Reef Fish Cephalopholis Argus(Epinephelidae) Indicates Pleistocene Isolation Across The Indo-Pacific Barrier With Contemporary Overlap In The Coral Triangle, Michelle R. Gaither, Brian W. Bowen, Tiana-Rae Bordenave, Luiz A. Rocha, Stephen J. Newman, Juan A. Gomez, Lynne Van Herwerden, Matthew T. Craig

Fisheries Research Articles

Background

The Coral Triangle (CT), bounded by the Philippines, the Malay Peninsula, and New Guinea, is the epicenter of marine biodiversity. Hypotheses that explain the source of this rich biodiversity include 1) the center of origin, 2) the center of accumulation, and 3) the region of overlap. Here we contribute to the debate with a phylogeographic survey of a widely distributed reef fish, the Peacock Grouper (Cephalopholis argus; Epinephelidae) at 21 locations (N = 550) using DNA sequence data from mtDNA cytochrome b and two nuclear introns (gonadotropin-releasing hormone and S7 ribosomal protein).
