Torres Strait Reef Line Fishery: Coral trout (Plectropomus spp.) catch rate analysis, with data to June 2022

Abstract

Following the 2019 preliminary stock assessment in Hutton et al. 2019, an updated analysis of coral trout (Plectropomus spp.) abundance indices in the Torres Strait Finfish Fishery was conducted using logbook data up to June 2022. The primary goal of this analysis was to identify trends in standardised commercial annual catch weights. A generalised linear model was used to standardise catch weights in kilograms per operation-day. Despite data limitations due to the small size of the fishery, catch rates have remained generally steady over the last decade and appear stable under current fishing pressure.
