The lack of biometric data on chondrichthyan species has impeded the implementation of management strategies essential for the conservation of sharks and rays captured using different fishing gears in coastal ecosystems. This study aims to assess morphometric relationships (length–weight [LW], length–dorsal length [DL], and length–disc width [DW]) and ...
