Many of the tangible benefits of catch share programs (e.g., reducing overcapacity) are dependent on the trading of shares. Additional trading-related questions (such as whether landings will change port or be concentrated geographically) are also important to the overall evaluation of a fishery, but are often asked only during post-implementation...
During the first three years (2007-2009) of the Gulf of Mexico red snapper IFQ program most quota lease trades were local, involving fishers that lived in the same communities. In 2010, the red snapper quota lease market changed as more IFQ participants began trading quota with fishers from different regions...
From 2012 through 2013, NOAA Fisheries Service conducted a study to collect participation, effort, and expenditure information related to ocean recreation activities in the United States. This study collected information from all 50 states and the District of Columbia in six, two-month waves. There were eight ocean recreation categories of...
"Rationalization” or the change to catch share management in fisheries has been shown to lead to the slowing of fishing activity, input and effort consolidation, cost savings, as well as new market and product development. The effects of rationalization on fishermen’s behavior become more complex when one accounts for the...
Electronic monitoring (EM) systems hold promise for the future collection of fishery-dependent data, either to supplement human at-sea observers or replace them. Several pilot studies have been conducted on EM in the New England groundfish fleet, though there are still on the water operational and shore-side protocols to further test...
Ecosystem externalities arise when one use of an ecosystem affects its other uses through the production functions of the ecosystem. We use simulations from a size-spectrum ecosystem model to investigate the ecosystem externality created by fishing of multiple species. The model is based upon general ecological principles and is calibrated...
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...
This study investigates optimal catch of Barents Sea stocks, namely Northeast Arctic Cod and Capelin in multispecies ecosystem. We solve a multispecies age structured bioeconomic model for predator-prey interaction. Barents Sea stock data from ICES are employed for model application. Among others, we also include sustainability constraint in the model...
The paper puts forward a model of the Pearl River Delta (PRD) fishery in the South China Sea that integrates the ecological, social and economic costs and benefits of fisheries activities in a multidisciplinary framework. In particular, In particular, we developed integrated model by linking a regional Social Accounting Matrix...
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...
