Abstract Punt, A. E., Deng, R. A., Dichmont, C. M., Kompas, T., Venables, W. N., Zhou, S., Pascoe, Hutton, Kenyon, R., van der Velde, and Kienzle, M. 2010. Integrating size-structured assessment bioeconomic management advice in Australia's northern prawn fishery. – ICES Journal of Marine Science, 67: 1785–1801. Three species fishery (Penaeus semisulcatus, P. esculentus, Metapenaeus endeavouri) are assessed using a population model that operates on weekly time-step. The parameters this...
Abstract Demands on freshwater for human use are increasing globally, but water resource development (WRD) has substantial downstream impacts fisheries and ecosystems. Our study evaluates trade-offs between WRDs ecosystem functioning considering alternative dam extraction options, diverse eco-hydrological responses catchment-to-coast connectivity. We used a data-driven ensemble modelling approach to quantify the of WRDs. WRD varied from weakly positive severely negative depending species,...
The seagrass communities of the Gulf Carpentaria were mapped and classified in terms their species composition, areas shoot surface above-ground biomass. A total 906.4 km2 habitat, fringing 671.1 km coastline was identified, sampled. Eleven (approx. 20% all known species) recorded. In all, 74% occur along open coastlines are characterized by depth-zoned distributions (intertidally subtidally), variable shoot-surface biomass values. Each zone dominated bfone or two following species:...
Coastal habitats are critical to the sustained production of many fisheries. It is important, therefore, that fishery managers obtain accurate estimates extent these habitats. This study investigated three methods estimating linear and area mangroves (commercially available topographic data, aerial photographs Landsat Thematic Mapper satellite imagery) in two regions northern Australia: Joseph Bonaparte Gulf (in particular, Berkeley Lyne Rivers) with typically narrow fringes (<50 m wide),...
Abstract The growing demand for freshwater resources has led to dam construction and water diversions in a majority of the world's large rivers. With an increasing freshwater, trade‐offs between allocations preservation ecological connections terrestrial marine ecosystems are inevitable. links formed by rivers flowing into ocean benefit many commercially fished species. degree which different species livelihoods fishers negatively impacted changes river flows due extraction or diversion is...
Abstract Understanding recruitment variability in marine fisheries has benefits for the stock management and dependent fishers’ ability to plan their income. Here, we overview past new research on complex dynamics of redleg banana prawns Penaeus indicus Australia’s Joseph Bonaparte Gulf assess themes dating back time Hjort identify challenges. During 2015 2016, prawn catches catch per unit effort decreased anomalously low levels, suggesting a substantial decrease biomass. We hypothesized...
Abstract Anthropogenic alterations to river flow could have repercussions for flow-dependent species downstream but few studies account these dynamic relationships or quantify impacts of altered flow. Scylla serrata—a widely distributed portunid crab—was used as an example a model on abundance and catch. Crab population dynamics were modelled across large semi-enclosed tropical sea in northern Australia. Environmental drivers, primarily flow, also temperature the Southern Oscillation Index...
The juveniles of red-legged banana prawns Penaeus indicus and white P. merguiensis are difficult to distinguish. Gel electrophoresis, with the enzyme malate dehydrogenase, clearly separated into species both large small prawns. Four morphological characters were measured from juvenile (identified using electrophoresis): three these provided reliable separation species. mean ratio distance anterior-most dorsal rostral tooth (first tooth) tip rostrum (L 1 ): between this second 1,2 ) was...
Port construction at McArthur River Mine in the western Gulf of Carpentaria, Australia, required dredging an access channel through a prolific seagrass community. A 4 km by 60 m dredged to 5 depth removed 18.95ha intertidal and shallow subtidal seagrass. Dredge spoil was pumped onshore settle multiple ponds before decant water returned gulf. Quantitative surveys community surrounding using Before After Control Impact Repeated measures (BACIR) experiment were conducted investigate effect on...
The multiple-use Moreton Bay Marine Park in eastern Australia was rezoned 2009, increasing the total no-take marine national park (MNP) from 0.5 to 16%. In present study we measured trends human use of areas using observed vessel position and categorisation during on-water aerial surveys before after rezoning. Measured changes spatial patterns fishing showed that effects rezoning on most activity minimal. After rezoning, proportion recreational declined 6.3 2.6% footprint new MNPs....
