Global seafood markets : challenges and solutions for consumers

Abstract

Human activities in and around the oceans are affecting the health of ocean ecosystems. In particular, the exploitation of natural resources such as fishing, likely has the greatest anthropogenic impact on the world’s marine ecosystems. Global fish landings decreased in the last 50 years in all countries due to continuous overfishing. Indeed, in the major fishing areas, as fishing intensity increased, catch per unit area of fishing effort has correspondingly decreased.
