Conservation challenges for small-scale fisheries: Bycatch and habitat impacts of traps and gillnets
Geoffrey G. Shester, Auteur ;
Fiorenza Micheli, Auteur
Small-scale fisheries provide over half the world's wild-caught seafood, employ over 99% of its fishers, and are frequently promoted as a sustainable alternative to large-scale industrial fisheries. However, few studies have quantitatively exami[...]
