Abstract Understanding how aquatic species respond to extremes of DO and temperature is crucial for determining they will be affected by climate change, which predicted increasingly expose them levels beyond their optima. In this study we used novel animal-borne DO, depth sensors determine the effect on vertical habitat use Atlantic salmon Salmo salar in aquaculture cages. Salmon showed a preference temperatures around 16.5 17.5 °C, however, selection preferred was trumped active avoidance...
Abstract Delineation of population structure (i.e. stocks) is crucial to successfully manage exploited species and address conservation concerns for threatened species. Fish migration associated movements are key mechanisms through which discrete populations mix thus important determinants structure. Detailed information on fish becoming more accessible advances in telemetry analysis methods however such not yet used systematically stock assessment. Here, we described how detections...
Understanding the links between external variables such as habitat and interactions with conspecifics animal space‐use is fundamental to developing effective management measures. In marine realm, automated acoustic tracking has become a widely used method for monitoring movement of free‐ranging animals, yet researchers generally lack robust methods analysing resulting spatial‐usage data. this study, data from male female broadnose sevengill sharks Notorynchus cepedianus , collected in system...

Estuarine habitats are frequently used as nurseries by elasmobranch species for their protection and abundant resources; however, global climate change is increasing the frequency severity of environmental challenges in these estuaries that may negatively affect physiology. Hyposmotic events particularly challenging marine sharks osmoconform, species-specific tolerances not well known. Therefore, we sought to determine effects an acute (48 h) ecologically relevant hyposmotic event (25.8 ppt)...
Abstract Understanding the way catchability of exploited fish species varies due to changes in individual behaviour is a seldom addressed but important requisite for extracting accurate information on abundance from catch per unit effort (cpue) data, particularly baited gears. In this study, cpue data analysis was combined with movement and activity acoustic telemetry tags determine nature seasonal recreationally caught sand flathead (Platycephalus bassensis) coastal bay estuary southeast...
Shark nurseries are susceptible to environmental fluctuations in salinity because of their shallow, coastal nature; however, the physiological impacts on resident elasmobranchs largely unknown. Gummy sharks (Mustelus antarcticus) and school (Galeorhinus galeus) use same Tasmanian estuary as a nursery ground; each species has distinct distribution patterns that coincident with changes local conditions, such increases salinity. We hypothesized these differences were directly related...

Determining the dynamics of ecological communities following periods anthropogenic change is critical to assessing effectiveness management strategies. Several coastal areas in south-eastern Australia were proclaimed shark refuge (SRAs) overfishing school (Galeorhinus galeus) during 1940s and 1950s. In conjunction with catch reduction measures, these provide spatial protection for juvenile G. galeus. present study, we compared recent (2012–14) historic (1991–97) longline rates determine...
Abstract Many sharks and other marine taxa use natal areas to maximize survival of young, meaning such are often attributed conservation value. The is linked predator avoidance or food resources. However, energetic constraints that may influence dispersal young their poorly understood.
