Start year 2012 End year 2015 Funding (€) € 305,002 Website NA Summary The purpose of this project is to investigate what kind of sharing agreement could be robust to the kind of changes in stock migrations as we have seen in the past. We intend to model this as a multispecies fishery including herring, mackerel and blue whiting in the Northeast Atlantic. There are three reasons for this. First, there are indications that the abundances of these stocks are related, where an increasing abundance of one stock can have negative effects on the other stock due to interspecific competition for food. Second, there is reason to believe that a more robust agreement could be attained if it encompasses all the three species involved, as one nation that at a certain time might be disadvantaged in terms of one species could be better endowed with respect to another. Agreements that might seem unfair and disadvantageous with respect to one species only could be more favourable when several species or stocks are considered jointly. Third, there are economic or fleet interactions, as each fleet harvests all species to some degree. We will develop a model which takes the migratory dimension into account. Further, we will do this by applying a seasonal approach, where a share of each stock is located in a given Exclusive economic Zone (EEZ) or the high seas in each season. These shares will be modelled as variable over time, to take into account the variability in migratory behaviour. To some extent this variability in migratory behaviour is likely to be stochastic, but we will also investigate whether it depends on abundance or whether there are long term decadal trends in migratory behaviour related to environmental variables such as ocean temperature and salinity. We will employ game theory to find feasible solutions to the sharing problem and investigate the stability of possible coalitions between the individual nations (the EU, the Faroe Islands, Iceland, Russia and Norway). We will model all three species involved and also take into account possible changes over time.
(1) To model a multi-species fishery including herring, mackerel and blue whiting; (2) Develop a model which takes the spatial (migratory) dimension into account; (3) Investigate the possibility of a relationship between individual growth and total biomass of pelagic fish for the different stocks involved; (4) Employ game theory to find feasible solutions to the sharing problem; (5) Provide empirical results that may assist policy-makers in the countries around the Northeast Atlantic to improve the management of the pelagic fisheries in the sense that it will resolve conflicts of interest and, thus, generate greater economic rents.
