THE NORWEGIAN SPRING-SPAWNING HERRING FISHERY: A STYLIZED GAME MODEL

This paper presents an empirically based, game-theoretic model of the exploitation of the Norwegian spring-spawning herring stock, also known as the Atlanto-Scandian herring stock. The model involves five exploiters; Norway, Iceland, the Faroe Islands, the EU, and Russia and an explicit, stochastic migratory behavior of the stock. Under these conditions Markov Perfect (Nash) equilibrium game strategies are calculated and compared to the jointly optimal exploitation pattern. Not surprisingly, it turns out that the solution to the competitive game is hugely inefficient, leading very quickly to the virtual exhaustion of the resource. The scope for cooperative agreements involving the calculation of Shapley values is investigated. Although the grand coalition of all players maximizes overall benefits, such a coalition can hardly be stable over time unless side payments are possible.Resource /Energy Economics and Policy,

The Ties That (Do Not) Bind: The ITQ System and Concentration in the Icelandic Fish Processing Industry, 1987-2004

This paper explores the reasons why the ties between harvesting and processing have been severed in the Icelandic fisheries in recent decades, and traces the role played by better transport, the emergence of domestic wet-fish markets, and the introduction of freezing trawlers, as well as other factors in this development. Attention then is focused upon increasing concentration in the processing industry, with special attention paid to the role played by economies of scale and the ITQ system, which was introduced in the main demersal fisheries in 1984 and, six years later, in all other fisheries

EMU and the Icelandic labour market

In this paper we look at the costs and benefits for Iceland from joining the EMU from a labour-market perspective. We conclude that none of Mundell's three criteria for an optimal currency area are at present fulfilled for Iceland and the initial Euro zone. Shocks to the Icelandic economy are found to be asymmetric with those experienced in other countries, nominal wages rigid, and migration limited. The painful adjustment of the Faeroese economy to macroeconomic shocks in the early 1990s suggests that the disadvantages of not having a separate currency can be substantial if nominal wages are rigid. Substantial variation in labour market participation and frequent adjustments of the exchange rate seem to have held unemployment in check in Iceland, at least until around 1988.

TECHNICAL EFICIENCY OF FISH AGGREGATING DEVICES ASSOCIATED WITH TUNA FISHERY IN KENDARI FISHING PORT – INDONESIA

Kendari fishing port is one of the biggest tuna fisheries landing in Indonesia. It yearly average tuna production was more than 20 thousand tons. The tuna fishing fleet in Kendari use FAD (Fish Aggregating Devices) as an auxiliary fishing gear. FAD management is major issues in Indonesian tuna fisheries. extensive investment on FAD has led to increase of the juvenile and by catch and also social problem because of the competition. Technical efficiency analysis was done during this study, 2015 catch and logistic data from Kendari fishing port was run using stochastic frontier to obtain the model. Mean value technical efficiency was 0.534. Purse seine the highest mean value compared to other fishing gear. All the variables input show positive relationship to the catch except the days at sea variables, this is a signal that the increasing number of FAD has made the fisherman spend more time at sea it will decrease the technical efficiency. The results support the need of FAD regulation done by the government of Indonesia. Regulation will keep the number of FAD at optimum level and increase the technical effieciency so the fisheries keep gaining the optimum benefit from the resources

Analysing uncertainties in socio-economic assessments of fisheries and aquaculture under climate change

Socio-economic analysis of seafood production is important for the conservation of aquatic ecosystems and the management of fisheries and aquaculture activities. Understanding how the livelihoods of people, dependent on the exploitation of aquatic resources, are affected by various changes is essential for decision making. The two main seafood production sectors, fisheries and aquaculture are fundamentally different. Whilst fishing is an extremely uncertain and complex system that operates in an ecological context where constant interactions between biology, ecology, climate, economics and sociology take place (FAO, 2017), aquaculture normally takes place in a considerably more controlled and contained production setting within the ecosystem. However, climate change will likely impact both sectors in various ways. This study presents how uncertainty is considered within the socio-economic assessments of two important economic activities in the Northeast Atlantic, one the salmon aquaculture operation in countries such as Norway, Scotland and the Faroe Islands and the pelagic fisheries in EU, Norwegian, Faroese and Icelandic waters. A novel approach in our assessment is the consideration of the uncertainties of input factors as consequences of climate change, resource abundance, technology, operators’ behaviour, market conditions, harvesting efficiency, governance policy, and socio-economic status of communities. Data collected by individual surveys and secondary sources are described as statistic distributions that are used for Monte Carlo simulations. Our simulation models enable researchers to predict the likelihoods of occurrence of socio-economic outcomes, and the contributions and sensitiveness of input variables to the profitability of seafood production and the gross value added to the economy

European Seafood Production under Climate Change: Assessing Economic and Social Consequences

Climate change has been observed to have a significant impact on the distribution of aquatic species and productivity of aquaculture systems across the globe. This affects the level of food production, the livelihoods of communities that depend on fisheries and aquaculture, and the future sustainability of these sectors. As in all other parts of the world, climate change will have inequitable and diverse impacts on economic growth across Europe, creating winners and losers. The European H2020 project ClimeFish investigates the impacts of climate change in aquatic food production at the European and regional scale, for the three main production sectors: marine fisheries, lakes and ponds and marine aquaculture. ClimeFish has developed a process for conducting socio-economic impact assessment by first identifying the effect(s) of climate change on the biological properties of both fish and aquaculture species, and secondly assessing the socio-economic impacts based on these biological forecasts, collecting additional socio-economic data and feedback from relevant stakeholders. Here, we provide an overview of the methods and work conducted in seven different case studies will be provided, focusing on both opportunities and threats within the three sectors and geographical locations around Europe as well as a European wide analysis. Challenges related to the data collection and analysis, as well as potential ways of overcoming them, are discussed
