Abstract The climate-driven redistribution of fisheries species is altering their availability to fishers, necessitating projections redistributions that directly relate future fishing opportunities. We propose a valuable proxy for opportunity the proportion year target are available which can be approximated by temporal persistence suitable habitat in defined regions. Here, we quantify changes (months/year) within five eastern Australian bioregions over period 2010–2060 four coastal-pelagic fishes: bonito (Sarda australis), spotted mackerel (Scomberomorus munroi), Spanish commerson) and dolphinfish (Coryphaena hippurus). When were analysed collectively, significant reduction environmental habitats was evident most equatorward (i.e. Tweed-Moreton) bioregion, while positive increases found poleward (e.g. Batemans Twofold Shelf bioregions). greatest projected bioregion Hawkesbury (+2.2 + 1.5 months/year between 10-year averages centered on 2020 2050, respectively). By demonstrating as measure opportunity, highlight potential this metric an effective means communicating stakeholders need adapt climate change.
