Fishery biomass trends of exploited fish populations in marine ecoregions, climatic zones and ocean basins
It's a journal called Estuarine, Coastal and Shelf Science.

The tragedy of the commons is a great launching point for understanding this problem. Managing fish populations is one of the best examples.
