Globally, sharks are experiencing population declines due to unsustainable harvest and high bycatch rates, posing significant resource and conservation concerns. Shark life history is typified by long lifespans, late maturity and low fecundity patterns that increases their susceptibility to overexploitation and drives slow population recovery. However, more recently small to medium sized sharks have been targeted by fishers due to the widely perceived notion that smaller species are more productive and resilient. This study aims to determine size-at-maturity and size-at-maternity for the spot-tail shark (n = 103), a small-bodied shark species that represents high commercial catch rates across northern Australia. Samples were collected from commercial fishing vessels in 2025. A range of reproductive components were measured, including total length, body weight, gonad weight, clasper length (male), ovarian follicle diameter, number of embryos and the size, weight and sex of embryos (females). Analysis involved fitting a Logistic Regression model in the FSA r package. Size-at-maturity results will be used as a proxy to determine the maturity of a previously unknown sample of C. sorrah from 2008 (n = 98). This will provide us with a dataset of n = 201 to analyse age-at-maturity in the future. Integrating updated biological information in stock assessments is essential for implementing well-informed fisheries management and regulatory practices to improve marine species monitoring. A concise overview of our results will be depicted in our poster.
