The term "commons" refers to collectively exploited resources and their systems of usage; a synonymous term is common pool resources. Fisheries are typical common pool resources and also one of the most conspicuous examples of unsustainable use of natural resources. We examine one of the few globally important fisheries that is held to be sustainable, the Peruvian anchovy fishery, and considers...

There is growing awareness of the impact fishery activities on fragile and vulnerable deep-sea ecosystems, stimulating actions devoted to their protection best management by national international organizations. The Bari Canyon in Adriatic Sea represents a good case study this, since it hosts threatened species, as well valuable commercial but virtually lacks substantial plans for sustainable u...

The shift in marine resource management from a compartmentalized approach of dealing with resources on a species basis to an approach based on management of spatially defined ecosystems requires an accurate accounting of energy flow. The flow of energy from primary production through the food web will ultimately limit upper trophic-level fishery yields. In this work, we examine the relationship...

1 The emergence of ecosystem-based management suggests that traditional fisheries man2 agement and protection of environmental quality are increasingly interrelated. Fishery 3 managers, however, have limited control over most sources of marine and estuarine pol4 lution and at best can only adapt to environmental conditions. We develop a bioeconomic 5 model of optimal harvest of an annual specie...
