Abstract

Understanding the impacts of climate change on marine habitats is essential for predicting future species distribution patterns and supporting sustainable fisheries management, particularly for commercially important apex predators. In this study, we used occurrence records from global databases (GBIF and OBIS) and published field surveys, combined with Bio-ORACLE environmental predictors, to model current and future habitat suitability of Caranx ignobilis (Forsskål, 1775) in the Persian Gulf. We implemented six individual modeling algorithms and three ensemble modeling techniques using the biomod2 platform. The ensemble model EMwmean (AUC= 0.992, TSS= 0.923) was selected for final projections because it integrates multiple algorithms and reduces model-specific bias. Based on variable importance analysis, sea surface temperature (SST), salinity, and primary production were identified as the most influential environmental predictors shaping habitat suitability. Future projections under SSP2-4.5 and SSP5-8.5 indicated progressive contraction of suitable habitat in the southeastern Persian Gulf, accompanied by a northwestward displacement of the habitat centroid. Specifically, the modelled area classified as suitable habitat is projected to decline from 48.49×10³km² under current conditions to zero by the 2090s under both SSP2-4.5 and SSP5-8.5, reflecting zero modelled suitable habitat under the applied threshold rather than biological extirpation. These findings provide spatially explicit information to support adaptive fisheries management and conservation planning, thereby enhancing the long-term resilience of this ecologically and commercially important reef-associated predator under future climate change in the Persian Gulf.
