Abstract:: Recreational fishing for popular species like red snapper and grouper in the Gulf of Mexico has followed a familiar pattern to that observed in many commercial fisheries: fishing under regulated open access has promoted a “race to the fish” with cascades of shorter seasons, shrinking bag limits, and significant fishery...

Abstract:: Fisheries sustainability is a much sought-after goal. Yet, “sustainability” is often too ambiguously defined to be of much practical guidance to policymakers. Furthermore, fisheries managers are increasingly expected to assess and manage fisheries in an “ecosystem-based” manner – accounting for the ecological interdependencies of species and their coupling with the...

Abstract:: Management objectives of vulnerable fish species must focus on maintaining healthy population status. Hence, reference points should be constrained to ensure recruitment. We assessed bioeconomic reference points for the totoaba (Totoaba macdonaldi), an endemic fish to the Gulf of California, reaching lengths of 2 m and 25 years. Totoaba fishing...

Abstract:: The Baltic fishery is managed under the European Union Common Fisheries Policy (CFP) which defines procedures for setting annual total allowable catches (TAC) for major commercially harvested species. TACs are given as fixed shares to each member state by applying the principal of relative stability. Poland uses non-tradable individual vessel...

Abstract:: Discount rates, it is well-known, play an important role in the determining optimal extraction paths for natural resources. In fisheries analysis, as well as other natural resource use, constant discount rates are customarily assumed. In practical applications, the constant discount rate is often taken to be the social rate of...

Abstract:: Ecologists warn that the rapid evolution occurring as a result of high-intensity commercial fishing could have potentially disastrous economic and ecological effects. The evolution of economically relevant life-history traits in fish, which can occur due to the harvesting pressure from commercial fisheries, can irreversibly diminish fisheries yields and ecological services....

Abstract:: Maryland, Pennsylvania, Virginia, and West Virginia have all developed nutrient trading programs to defray the cost of achieving mandated nitrogen load reductions in Chesapeake Bay, and there is increasing interest in the role oysters can play in generating credits. A number of bioeconomic models highlight the impact these credits have...

Abstract:: This research analyzes the effects that a redistributive fishing quota policy, within a collective rights quota assignment system, might have on the profits and employment of artisanal fisher organizations. The Chilean authorities have been pursuing a deliberate quota redistributive policy between ship-owners of different vessel categories. This policy has affected...

Abstract:: Early studies of economies of scale show that ownership limitations imposed large costs on salmon farming firms prior to the deregulation of the industry in 1991. Since then a number of mergers and acquisitions have taken place and the industry has become far more concentrated. Despite this, a number of...

Abstract:: During last decade, the excluding efficiency of circle hooks for sea turtle has given positive and successful outcomes in Oaxaca, Mexico. The research seeks: 1) determine if the change of fishing gear provides positive benefits to local small scale longline fishermen, 2) estimate the benefit and cost functions, 3) determine...
