Marine vertebrate bycatch: problems and solutions


One of the first ESR Specials (Fisheries bycatch: problems and solutions [2008]) explored the burgeoning field of bycatch research, focusing primarily on bycatch of sea turtles, sea birds and marine mammals. Many of its 24 articles became highly influential. Even a decade ago, bycatch of marine megafauna was not a new problem in fisheries management but was already recognized as being of pressing conservation concern. In the intervening years, research into both the problem of fisheries bycatch and the possible solutions has advanced in great strides. This ESR Special assesses where the situation has improved or worsened and identifies the key opportunities and barriers to making progress.


Articles belonging to this Special were published upon completion in the respective volume of ESR. They are listed below as well as on the contents page of the respective volume of publication.


Status: Complete.
