In this paper, a discrete time, multi-gear and age structured bio-economic model is developed for the Northern Atlantic Bluefin Tuna, which is a paradigmatic example of the difficulties faced in managing highly migratory fish stocks. The 1995 U.N. Fish Stocks Agreement provides guidance as to...

Large-scale use of nitrogen-based chemical fertilizers, specific to intensive agriculture, has undesirable effects consisting of soil degradation and atmospheric loading with carbon dioxide. Good practice illustrates, however, that sustainable agriculture can be achieved by substituting as much...

The paper reports the results of a bioeconomic analysis of the exploitation of a recently discovered orange roughy stock located off Tasmania. The parameters of the model are based on the experience derived from the orange roughy fisheries in New Zealand where stocks have been heavily exploited....
