  Citation × Citation Citation Abstract Copy Title: Impacts of Vessel Capacity Reduction Programs on Efficiency in Fisheries: the Case of Australia's Multispecies Northern Prawn Fishery Author: Coglan, Louisa, Punt, Andre E., Dichmont, Catherine M., Pascoe, Sean Capacity reduction programs in the form of buybacks or decommissioning programs have had relatively widespread application in fisheries in the US, Europe and Australia. A common criticism of such programs is that they remove the least efficient vessels first, resulting in an increase in average efficiency of the remaining fleet. The effective fishing power of the fleet, therefore, does not decrease in proportion to the number of vessels removed. Further, reduced crowding may increase efficiency of the remaining vessels. In this paper, the effects of a buyback program on average technical efficiency in Australia’s Northern Prawn Fishery are examined using a multi-output distance function approach with an explicit inefficiency model. The results indicate that average efficiency of the remaining vessels was greater than that of the removed vessels, and that average efficiency of remaining vessels also increased as a result of reduced crowding.

  Citation × Citation Citation Abstract Copy Title: Incorporating Habitat Dynamics into Bioeconomic Model of Fishery. Application to Artificial Reefs Author: Cartigny, Pierre, Ami, Dominique, Udumyan, Narine In this paper the emphasis is put on an important aspect of renewable resource use that was disregarded until now. It is the evolution of environmental carrying capacity which is traditionally interpreted as a maximal population level that can be supported by the environment (or by habitats of which it consists). Hence we adapt the Gordon-Schaefer model with constant carrying capacity by incorporating time-dependent carrying capacity that determines the state of habitats. They are subject to some biological processes (habitat rehabilitation) as well as to human aggressions (in particular habitat degradation due to fishing). Based on the developed model, we reassess the recommendations considered as a benchmark for resource managers until recently. Under simple hypotheses on the form of habitat (carrying capacity) dynamics, the current study has shown the importance of the latter for the design of management tools. When dynamic patterns of habitats are not taken into account, fishery recommendations based on Gordon-Schaefer model can be aberrant and lead to the collapse of the fishery. The presented model allows not only to enrich the design of management tools but also to assess the performance of artificial reefs, a promising ecosystem-based tool widely used in some coastal areas. The economic benefits of artificial reefs are still not well studied and represent a challenge to take up. Since artificial reefs are conceived as replacement for natural habitats, they assume the same role as these latter. Therefore the structure of our model seems appropriate to evaluate this particular management tool. Title: Incorporating Habitat Dynamics into Bioeconomic Model of Fishery.

Year: 2001 Management of fishing effort and fishing capacity is receiving increased attention world-wide. In the Northeast region of the U. S., the principal focus has been on managing “active” fishing vessels, although concerns have increased over the magnitude of “latent” effort and its implications for resource recovery and sustainability. This paper reviews current and historic levels of latent fishing effort in the Northeast U.S. groundfish fishery and examines patterns of latent to and active effort, particularly as they may be affected by vessel ownership transfer.

  Citation × Citation Citation Abstract Copy Title: Thoughts on Productivity, Efficiency and Capacity Utilization Measurement for Fisheries Author: Paul, Catherine J. Morrison Year: 2001 The author highlights the many new insights that have already arisen in the rapidly emerging literature on performance and CU measurement in fisheries. She stresses two fundamental points. First, for relevant policy guidance it is crucial to seriously ponder the implications of myriad complicating factors for CU modeling and measurement, many of which arise due to unique and key characteristics of fisheries industries, rather than sweeping them under the rug. Second, stochastic methods have potential for incorporating these types of structural characteristics into production models, and thus measurement of performance/CU, even though they have not yet been used much in this literature and may be somewhat more complex to implement than DEA approaches.
