In recent years a number of marine protected areas (MPAs) aimed at restoring fishing stocks and ecosystem managements have been established. Yet, consensus about creating processes of MPAs (e.g., preliminary observation or configuration of MPAs) has not been gained. In this talk I suggest a method for deciding a mesh size in geographic assessments before the creation of MPAs.
Selective fisheries may cause larger impacts on marine ecosystems than unselective fisheries (Garcia et al. 2012). However, bycatch, which is inevitable especially for multispecies fisheries, has also serious impact on sustainable fisheries and marine ecosystem. I investigate impacts of bycatch on marine ecosystems and discuss the way to address this problem.
