Abstract Debate about the potential benefits and risks of live sonar technology (also known as imaging forward-facing sonar) in freshwater recreational fisheries includes growing discussions regarding regulation. Synthesizing sparse literature, experiences coauthors, observations from traditional social media, we revealed a varied range outcomes for when this is used. Of particular concern ability to find fish that were previously cryptic target them ways increase capture efficiency (e.g.,...
Fish stocking is commonly used in developed countries and aims to improve recreational fish stocks rebuild threatened species populations. often contentious due its high investment, limited scientific evaluation, typically divided opinion from key stakeholders. Debates over the efficacy effects of continue occur absence information about current past practices, their degree alignment with accepted responsible approach previously published platform papers. Consequently, using Australia as a...
Abstract The golden perch Macquaria ambigua is a recreationally important freshwater sport and food fish species found throughout southeastern Australia. Stocking in impoundments has been used by fisheries managers to enhance existing wild populations for over 30 years. Despite widespread stocking, the contribution of stocked not investigated. We evaluated stocking using chemically marked fingerlings introduced into three lakes which natural recruitment low. surveyed determine lake an...
Although recruitment is often influenced by microhabitat characteristics that affect larval settlement and post-settlement growth survival, the influence of some habitat features, such as presence conspecifics accessibility food, are poorly understood, particularly on temperate reefs. We investigated ecological determinants in southern hulafish (Trachinops caudimaculatus; McCoy, 1890), a small zooplanktivorous reef fish Port Phillip Bay, Australia. hypothesised T. caudimaculatus would show...
Density-dependent processes resulting from fish stocking were demonstrated to have a significant impact on recreational fishery performance, and this case study will be of use guide decisions in other fisheries. We evaluated put-grow-and-take lake program for Chinook salmon (Oncorhynchus tshawytscha) located south-western Victoria, Australia. hypothesised that performance would show density-dependent relationships with stocking. To test hypothesis, we used Wald F tests general linear...
Abstract Macquarie perch, Macquaria australasica Cuvier, is an endangered Australian freshwater fish that has historically supported popular recreational fisheries, but since the 1980s, it experienced a decline in both distribution and abundance. This study investigated whether marked population size of perch occurred at Lake Dartmouth between mid‐1980s 2000 likelihood current legal minimum length (LML) 350 mm TL protecting from recruitment overfishing. Recreational angler survey data showed...
Abstract Because of the high costs collecting field data, many species recovery and management plans do not include a monitoring feedback component to measure success interventions refine strategies. Here, we demonstrate how leveraging existing data can provide broad‐scale, cost‐effective information about threatened fish species, Murray Cod Maccullochella peelii , which is cultural recreational importance in Australia. We applied Bayesian hierarchical model abundance catch collected as part...
Abstract Quantitative measures of fish habitat in lakes and impoundments have seldom been proposed. The availability Geographic Information Systems (GIS), however, now provides a means for researchers to assess on whole‐lake scale. GIS modelling was used this study quantify the impacts stratification amount distribution brown trout ( Salmo trutta ) large reservoir Victoria, Australia. Species‐specific temperature dissolved oxygen tolerance ranges were applied hydrological profile lake...
Freshwater crayfish support significant commercial and recreational fisheries worldwide. The genus Cherax is fished in Australia with a variety of fishing gears, yet little known the relative efficiency different gears methods. Additionally, freshwater-crayfish traps can pose risk to air breathing by-catch such as aquatic mammals, reptiles birds, so mitigation important. We sought understand whether be undertaken efficiently, using passive nets, without undue air-breathing species. In...
The effects of climate and land-use change, coupled with limited management resources, mean that managers are increasingly faced decisions to invest in some locations at the expense others. Given their potentially controversial nature, such require predictions likely outcomes under different strategies potential future climates. We develop an approach prioritise interventions across multiple highly variable uncertain environments, using a stochastic model population dynamics structured...
