One of the main goals stated in the proposals for the Common Fisheries Policy (CFP) reform is achieving maximum sustainable yield (MSY) for all European fisheries by 2015. In this paper, we consider the mechanism design problem for allocation of fishing rights to achieve MSY harvesting conditions. We study an age-structured fish population model and apply this model for a fishing environment including two fishermen having perfect or imperfect fishing selectivity. If we assume that fishermen are non-satiated and they fulfill their remaining quotas through capturing untargeted (less revenue-generating) fish after targeted fish population is fully caught, the fix ratio of the catch of targeted fish to untargeted fish, derived from catchability coefficients, is not valid anymore. As a result, we show that not only the age-structure or fishing technology but also the estimated level of MSY is steering the optimal allocation of quotas. Accordingly, we determine technology-based optimal quota shares for each fisherman at particular MSY levels. We also show that the optimal allocation of fishing quotas does not have a bang-bang nature under imperfect fishing selectivity.

Quota implementation of the maximum sustainable yield for age-structured fisheries Kanik, Zafer; Küçükşenel, Serkan (Elsevier BV, 2016-6) One of the main goals stated in the proposals for the Common Fisheries Policy (CFP) reform was achieving maximum sustainable yield (MSY) for all European fisheries. In this paper, we propose a fishing rights allocation mechanism or management system, which specifies catch limits for individual fishing fleets to implement MSY harvesting conditions in an age-structured bioeconomic model. An age-structured model in a single species fishery with two fleets having perfect or imperfect fishing selectivity is stud...
The promise of transferable fishing concessions on EU fisheries Kanik, Zafer; Küçükşenel, Serkan (2017-05-01) Two of the main proposals for the reform of the European Union (EU) Common Fisheries Policy (CFP) in 2011 were related to maximum sustainable yield (MSY) and transferable fishing concessions (TFCs). The European Commission (EC) proposed the goal of achieving MSY for all European fisheries. The EC also proposed implementation of TFCs under some major principles including reserving a part of total quotas for small-scale fishermen in order to prevent the disappearance of small-scale fishing communities in coas...
Design and Implementation of Optimal Management Systems for European Fisheries (DIOMFISH) Küçükşenel, Serkan(2010-9-1) The purpose of this research project is to develop an optimal management mechanism for the economic and social sustainability of European fisheries. Throughout the project, development and feasibility of a rights based management mechanism which efficiently allocates the fishing rights in Member States will be investigated. This mechanism will not have a high data demanding characteristic and will also be adaptable to other regions of fisheries in the third countries. Currently, Common Fisheries Policy (CFP...
The Promise of Transferable Fishing Concessions on EU Fisheries Kanık, Zafer; Küçükşenel, Serkan (2014-04-11) Two of the primary issues of the next Common Fisheries Policy (CFP) reform are maximum sustainable yield (MSY) and transferable fishing concessions (TFCs). The European Commission set the goal of achieving MSY for all European fisheries by 2015. Besides, the European Commission agreed on implementing TFCs under some major principles including reserving a part of total quotas for small-scale fishermen in order to prevent the disappearance of small-scale fishing communities in coastal regions. The interrelati...
Assessment of Model Uncertainty in the Prediction of Seasonal and Annual Variability in the Black Sea Salihoğlu, Barış; Fach, Bettina Andrea; Akoğlu, Ekin (2016-02-15) A new generation (circulation, biogeochemical and a higher trophic level) model for the Black Sea was developed to provide an integrated analysis of ecosystem attributes that contributes to policy oriented criteria's of the European Union's ambitious Marine Strategy Framework Directive towards achieving Good Environmental Status by 2020. The biogeochemical model, including the carbonate module, comprises thirty state variables. The higher trophic level model includes thirteen fish species. The model system ...
