Here we report findings regarding the reproductive biology of swordfish Xiphias gladius in Corsican waters in the north-western Mediterranean Sea. We sampled 558 swordfish (72–216 cm; lower jaw to fork length, LJFL) caught from June to September in 2019

To preserve marine biodiversity, we need reliable early warning indicators that inform changes in marine ecosystems. As reliable samplers of mid-trophic level communities, studying the trophodynamics of large pelagic fish can contribute to monitoring

Accurate age estimates for fish are critical for properly understanding stock dynamics and health; this is particularly true for larger billfishes. Here we determined the most accurate aging estimation methods for swordfish (Xiphias gladius). We compared
