Megafauna are integral to the biodiversity of the globe, yet many species face significant threats from anthropogenic activities. In Australia, various fishing gear are deployed at popular beaches as part of a management strategy to regulate potentially dangerous shark populations. The Critically Endangered grey nurse shark (Carcharias taurus) is susceptible to incidental capture by equipment, which is considered to be a major factor limiting the population’s recovery. Using catch data, the IMOS receiver network and remotely sensed environmental data, we investigated how spatio-temporal patterns of C. taurus capture in shark control program equipment relate to residency and movement patterns of tagged individuals, and what temporal oceanographic anomalies drive them to move. Between 2012 – 2022, there were 283 captures of C. taurus, 74 ending in mortality. Female sharks were at particular risk, comprising 80% of captures and 81% of mortalities. The location and timing of C. taurus captures overlaps with observed movement patterns across our study. Modelling temporal anomalies uncover various relations between some movements and oceanographic currents, height, temperature and lunar phases. Our findings highlight opportunities for mitigating incidental capture of threatened C. taurus in SCPs through seasonal closures, selective gear deployment, and continued exploration of new technologies.
