  Citation × Citation Citation Abstract Copy Title: A Bioeconomic Analysis of the Impact of Buyback Programs: Application to a Limited Entry Scallop French Fishery Author: Fifas, Spyros, Guyader, Olivier, Daures, Fabienne Year: 2001 The objective of the paper is to analyse and to simulate fishers dis-investment behaviour especially in the context of the French buyback policy. A case study, the limited entry scallop fishery of the Saint-Brieuc bay is used to consider the problem of excess capacity and to review the impact of the national decommissioning schemes on the scallop fleet. The role of financial incentives technical and economic are studied to explain individual decisions to stay or to leave the fishery. Considering these lessons, the second part of the paper aims at modelling fishers’ behaviour in order to simulate the bioeconomic impacts of buyback programs and the role of different incentive schemes. Special attention is paid to the assessment of willingness to accept to leave the fishery. The model is applied to the scallop fishery while highlighting agency problems such as the role of the regulator’s information about fleet and cost structure. The problem of windfall gains problem due to the mis-specification of the buy-back programs is analysed. Spreadsheet simulations lead to cost-benefit analysis of different policy options.

• 5. [Article] Estimating MSY and MEY in Multi-Species and Multi-Fleet Fisheries: The Case of the Bay of Biscay Mixed Fisheries

  Citation × Citation Citation Abstract Copy Title: Estimating MSY and MEY in Multi-Species and Multi-Fleet Fisheries: The Case of the Bay of Biscay Mixed Fisheries Author: Guillen, Jordi, Merzéréaud, Mathieu, Fifas, Spyros, Macher, Claire, Bertignac, Michel, Guyader, Olivier Most fish stocks worldwide are not optimally exploited and are therefore are producing less in biologic and economic terms that what it could be obtained. MSY objective for all the stocks by 2015 is put forward by several countries as management target to be achieved, while other countries such as Australia have moved towards MEY as target. In multi-species and multi-fleet fisheries however single species assessments and MSY and MEY reference points are often not valid. In this paper, we analyze the calculation of MSY and MEY in multi-species and multi-fleet fisheries, applied to the Bay of Biscay demersal fisheries. Estimations of MSY and MEY performed in this paper show that increases of the overall landings and economic performances can be obtained by fishing effort reductions and global selectivity improvements in the Bay of Biscay demersal fishery. In this paper we have also shown the importance of accounting for the multi-fleet nature of the fisheries, and so the capacity to allocate fishing effort between fleets to obtain better yields taking into account joint production processes, various métiers and reallocation of effort (both in production and economic terms). Estimating profitability changes when fishing at MEY and in the current situation of overcapacity and overexploitation offers an estimation of the costs of not fishing at MSY and MEY.
