INTRODUCTION Chondrichthyans (sharks, rays, and chimaeras) play a key role in the regulation of marine ecosystems by controlling prey population dynamics and maintaining trophic connectivity across habitats (Dedman et al., 2024). However, their slow life-history traits (low fecundity, late maturation, and extended lifespans) make them highly vulnerable to anthropogenic pressures, primarily driven by fishing exploitation (Dulvy et al., 2021).

Abstract Defining and protecting critical habitats for elasmobranchs (sharks and rays), such as spawning areas, is essential for mitigating anthropogenic pressures that threaten their populations, primarily driven by fisheries and habitat degradation. This study presents a novel modelling-based framework to identify Potential Spawning Areas (PSAs) - habitats offering optimal conditions for oviposition.
