Extremely Low Sample Size Allows Age and Growth Estimation in a Rare and Threatened Shark Open
Understanding life history parameters is key to assessing demography, biological productivity, and extinction risk of fishes. Age and growth analyses in chondrichthyan fishes (sharks, rays, and ghost sharks) is primarily undertaken through…

Using hydraulics to evaluate ecological benefits, risks, and trade‐offs from engineered flooding Open
Regulation and water extraction have reduced river flow worldwide. In some rivers, this has led to reductions in the frequency and duration of floodplain inundation and, in turn, declining condition of flood‐dependent vegetation. One manag…

Extremely low sample size allows age and growth estimation in a rare and threatened shark Open
Understanding life history parameters is key to assessing biological productivity, extinction risk, and informing the management of exploited fish populations. Age-and-growth analyses in chondrichthyan fishes (sharks, rays, and ghost shark…

Life history and demographic modelling of shark species caught in Indo-Pacific fisheries Open
Understanding a species' life history and its demographics is paramount to effective population and fisheries management. Many aspects of a species life history are reflected in how it grows – making accurate estimates of age and growth so…

Age, growth and maturity of Southern Ocean skates (Bathyraja spp.) from the Kerguelen Plateau Open
Three species of Southern Ocean skates, Bathyraja eatonii, Bathyraja irrasa and Bathyraja murrayi, are commonly caught as incidental by-catch in fisheries around Heard Island and McDonald Islands of the Kerguelen Plateau. We used length-at…

Using otolith chronologies to identify extrinsic drivers of growth of 2 commercially targeted small pelagic fish species Open
Climate variability is a major cause of changes in marine ecosystems, including changes in both the environment and in many fish species. Understanding the factors influencing key biological characteristics, such as growth, is important fo…

Modernising fish and shark growth curves with Bayesian length-at-age models Open
Growth modelling is a fundamental component of fisheries assessments but is often hindered by poor quality data from biased sampling. Several methods have attempted to account for sample bias in growth analyses. However, in many cases this…

Increasing the precision of the daily egg production method; 2020’s remix of a 1980’s classic Open
This paper reviews application of the Daily Egg Production Method (DEPM) to sardine (Sardinops sagax) off southern Australia between 1995 and 2019. Coefficients of variation (CVs) of estimates of spawning biomass (SB) were reduced from 23–…

Intraspecific demography of the silky shark (Carcharhinus falciformis): implications for fisheries management Open
The silky shark (Carcharhinus falciformis) is one of the most heavily fished tropical shark species globally, and currently there is increasing concern for its conservation status. However, large differences and ambiguity in life history p…

Age, growth and maturity of the Australian sharpnose shark Rhizoprionodon taylori from the Gulf of Papua Open
Coastal sharks with small body sizes may be among the most productive species of chondrichthyans. The Australian sharpnose shark (Rhizoprionodon taylori) is one of the most productive members of this group based on work in northern and eas…

Age, growth and maturity of oceanic whitetip shark (Carcharhinus longimanus) from Papua New Guinea Open
Oceanic whitetip sharks (Carcharhinus longimanus) in the Western Central Pacific have been overfished and require improved assessment and management to enable planning of recovery actions. Samples from 103 individuals (70 males and 33 fema…

Effects of Including Misidentified Sharks in Life History Analyses: A Case Study on the Grey Reef Shark Carcharhinus amblyrhynchos from Papua New Guinea Open
Fisheries observer programs are used around the world to collect crucial information and samples that inform fisheries management. However, observer error may misidentify similar-looking shark species. This raises questions about the level…
