A wide range of activities are reported here, from analysis of the global catch and landings data base of FAO, conclusions on global fishery trends, and more specific reviews on trends in Atlantic, Mediterranean and Black Sea fisheries, and some of the factors underlying them. Theoretical perspectives on causes are provided, showing, inter alia, that long term changes are occuring, not only in the pulse of global fishing effort that affected oceanic systems, starting from the Second World War until today,, but also by the eutrophication of semi-enclosed seas due to run off of nutrients and harmful industrial by products from human activities on land.
