Density-Dependence Inside A Marine Protected Area Increases Natural Mortality And Stunts The Growth Of A Spiny Lobster, Simon De Lestang, Emma Jade Tuffley
Density-Dependence Inside A Marine Protected Area Increases Natural Mortality And Stunts The Growth Of A Spiny Lobster, Simon De Lestang, Emma Jade Tuffley
Fisheries Research Articles
Sustainable fisheries management often requires the modelling of stocks under unfished conditions, when the influence of population densities on animal growth and mortality can be substantial. This can be especially true for species such as spiny rock lobster, which are very habitat specific. Using western rock lobster (Panulirus cygnus) tag-recapture data from adjacent and similar fished and unfished areas, the key life history parameters of natural mortality and growth were examined and compared under different population density scenarios. In an area representative of virgin biomass levels, lobsters exhibited reduced growth rates and a substantially higher rate of natural mortality …

Estimation Of Effective Number Of Breeders And Effective Population Size In An Abundant And Heavily Exploited Marine Teleost, Andrea Bertram, Justin Bell, Chris Brauer, David Fairclough, Paul Hamer, Jonathan Sandoval-Castillo, Maren Wellenreuther, Luciano B. Beheregaray
Fisheries Research Articles
Obtaining reliable estimates of the effective number of breeders (Nb) and generational effective population size (Ne) for fishery-important species is challenging because they are often iteroparous and highly abundant, which can lead to bias and imprecision. However, recent advances in understanding of these parameters, as well as the development of bias correction methods, have improved the capacity to generate reliable estimates. We utilized samples of both single-cohort young of the year and mixed-age adults from two geographically and genetically isolated stocks of the Australasian snapper (Chrysophrys auratus) to investigate the feasibility of generating reliable Nb and Ne estimates for a …

Long Term Sustainable Use Of Demersal Gillnet And Demersal Longline In Western Australia’S Temperate Shark Fisheries - Fisheries Research Report 340, Matias Braccini, Jack Parker, Daniela Waltrick, Maddison Watt, Nick Blay, Clinton Syers
Fisheries research reports
The Temperate Demersal Gillnet and Demersal Longline Fisheries (TDGDLF) are one of the main commercial shark fisheries in Australia. Most fishers in the TDGDLF use demersal gillnets to target sharks with scalefish taken in smaller amounts. Demersal longlines are also permitted but are not widely used. Demersal gillnets are size selective, but they do not necessarily discriminate among species, catching target and non-target species.
The Western Australian Fishing Industry Council (WAFIC) received funding as part of the Australian Government’s Our Marine Parks Grants Program to undertake research on the TDGDLF. This project was administered under the direction of a steering …

Puerulus Settlement Forecasting In A Harvest Strategy Evaluation Of The Rock Lobster Fishery In South Australia, Richard Mcgarvey, Adrian Linnane, John E. Feenstra, Janet M. Matthews, Lachlan J. Mcleay, Annabel Jones, Kyriakos Toumazos, Simon De Lestang
Fisheries Research Articles
Harvest strategies are utilised in the management of fishery resources globally. Critical to their success is harvest strategy evaluation, whereby future performance is assessed through projection modelling. Using the observed relationship between a puerulus settlement index and model-estimated recruitment, we evaluated a southern rock lobster (Jasus edwardsii) harvest strategy in South Australia. Short-to-medium puerulus settlement recruitment forecasting was incorporated into future projections of catch, catch per unit effort, and percent unexploited egg production (%UEP) during 2019–2022. Observed values of indicators that closely aligned with projected outputs indicated that puerulus forecasting underpinned reliable evaluation of future fishery performance. A …

High-intensity, impulsive sounds are used to locate oil and gas reserves during seismic exploration of the seafloor. The impacts of this noise pollution on the health and mortality of marine invertebrates are not well known, including the silverlip pearl oyster (Pinctada maxima), which comprises one of the world's last remaining significant wildstock pearl oyster fisheries, in northwestern Australia. We exposed ≈11,000 P. maxima to a four-day experimental seismic survey, plus one vessel-control day. After exposure, survival rates were monitored throughout a full two-year production cycle, and the number and quality of pearls produced at harvest were assessed. Oysters from two …

Workshop Abstracts: The International Conference & Workshop On Lobster (And Crab) Biology And Management, Department Of Primary Industries And Regional Development, Western Australia, Western Rock Lobster Council, Fisheries Research And Development Corporation
International Conference on Lobster (and Crab) Biology and Management (ICWL)
The theme of the 12th ICWL is ‘ecosystem-based fisheries management (EBFM)’. EBFM is a holistic approach to fisheries management that recognises all the interactions within an ecosystem rather than considering a single species or issue in isolation. We consider this represents best practice for fisheries management and reflects that fisheries research and management focus is now broader than just sustainability. Therefore, in addition to presentations that focus on lobster (and crab) biology and stock assessment, we have also welcomed presentations that examine other aspects of EBFM, such as ecosystem effects of fishing, economic assessments, social issues, governance, and compliance with …

Utility Of Body And Otolith Morphometry To Discriminate Cryptic Juveniles Of Two Sympatric Red Snappers (Perciformes: Lutjanidae), Miwa Takahashi, Corey B. Wakefield, Stephen J. Newman, Kyle B. Hillcoat, Benjamin J. Saunders, Euan S. Harvey
Fisheries Research Articles
The sympatric red snappers, Lutjanus erythropterus and Lutjanus malabaricus, are highly valued by commercial and recreational fishers along the tropical northern coasts of Australia and throughout their distribution. Studies on the life history and ecology of these congeners are confounded by difficulties in distinguishing the cryptic juveniles of each species (i.e., < 200 mm total length). This study aimed to validate a robust and cost-effective method to discriminate these juveniles using body and/or otolith morphometric data in a multivariate analysis. Juvenile samples were collected from the northwest (n = 71) and northeast (n = 19) coasts of Australia, and species identification was confirmed using DNA barcoding. The most parsimonious multivariate models achieved accurate species prediction rates of 98.8%, which consisted of just three body variables (dorsal fin length, the distance from the snout to the anterior edge of the eye, and either jaw length or distance from the snout to the preoperculum). The high level of discrimination for these cryptic juveniles highlights the robustness of this morphometric approach. The slightly lower rate of discrimination using otolith morphology (84.9%) was associated with greater regional variation in L. malabaricus between the northwest and northeast coasts. Slight variations in otolith shape are typically used to determine stock structure, which highlights the potential need to collect samples over a broader area of a species geographic range when using an otolith morphometric discrimination model. The method outlined in this study could be applied to distinguish other cryptic congeneric fish species, including from archived otolith collections. Moreover, this method has the potential to be utilized in assessing species compositions using body measurements from in situ stereo-video.

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.
