Shifting from marine reserves to maritime zoning for conservation of Pacific bigeye tuna (Thunnus obesus).

The remainder is landed in longline fisheries directed at BET and sold as fresh or frozen tuna at prices greater than US$10/kg.

The Western and Central Pacific Fisheries Commission (WCPFC) agreed to close certain high-seas areas in the Western and Central Pacific Ocean to purse seine tuna fishing starting in 2010. These measures have potential economic benefits to the countries surrounding the closed areas and may also have potential stock conservation benefits for tunas. We used a spatially explicit ecosystem model of ...
