Stakeholder perceptions of enhancement opportunities in the Chilean small and medium scale mussel aquaculture industry

The Chilean mussel aquaculture industry is a prime example of a thriving industry.  However, the industry growth rate, aquaculture concessions and market prices have stabilized signaling a shift in the industry from exponential growth to, if handled correctly, economic stability.  Here we used perception research, an efficient tool to inform on the implementation of management strategies, to provide policy makers with the tools necessary for the development of strategies that will aid in the sustainability of the industry through its current shift.  We assessed the perception

¿Ha contribuido el desarrollo de la salmonicultura en la Región de Los Lagos a la reducción de la pobreza rural? Una mirada empírica desde ingreso

We analyze if poorest people in rural localities of Región de Los Lagos, Chile have benefited in terms of poverty alleviation with salmon farms establishment within 1992-2002 period.  In order to assess the impact of this event on poverty, we compare areas with and without salmon farms.  We calculate poverty rates through small area estimation models at household level and we approach through differences in differences.  Our findings suggest, that poverty decreased more in localities with salmon farms than in those who do not.  We also identify geographic distances, betw

Exploring typologies of artisanal mussel seed producers in southern Chile

Aquaculture is on the most dynamic food production systems in the world, with a fast expansion, especially in developing countries.  Among this sector, the Chilean mussel industry has experienced a substantial increase, turning Chile into one of the leading producers and global exporters of mussels.  Among the different links in the mussel production chain, the natural seed collection conducted by artisanal fishers of southern Chile has been a fundamental pillar for the development of the industry.  Often, this sub-sector  has been thought of as a  homogeneous group

    Measuring Potential Rents in the North Sea Herring Fishery

    This paper assesses the potential for rent generation in the North Sea herring fishery. The assessment distinguishes between rents and intra-marginal profits—the sum of which constitutes variable profits in the fishery. A bioeconomic model combining fish population dynamics and the economics of the fishery is constructed to allow the computation of these different components of profits. In order to assess the dynamics of both rents and intra-marginal profits, the model is computed under various assumptions with regard to price, costs, and discount rates.

    Assessing Stakeholder Adaptive Capacity to Salmon Aquaculture in Norway

    This paper explores the socio-ecological effects of increased aquaculture/farmed fish production, around the island group of Frøya in Trøndelag, Norway, as a result of new licenses accorded to the industry. This is investigated from a stakeholder perspective by assessing the adaptive capacity of selected stakeholder groups through workshops combining Scenario Analysis, Systems Thinking and Bayesian Belief Network and by developing conceptual frameworks and structural diagrams that visualize the perceived effects of the industry on the given stakeholder system.

    Economic and Environmental interactions between salmon aquaculture and artisanal fisheries: “An Application of Reloncavi estaury”

    A bio-socio-economic model was developed to analyze the economic and environmental interactions between the aquaculture activity and artisanal fisheries related to the seed settlement of Mytilus Chilensis that is realized in the Reloncaví Fjord. Meaning by economic interactions the effects of the action of both productivities activities has on the employment and production variables of this sectors. And for environmental interactions the effect that has the aquaculture activity on the seed settlement activity, in terms of the uneaten food pellets (nutrients).

    CINTERA: A cross-disciplinary integrated eco-systemic eutrophication research and management approach

    CINTERA is designed to improve knowledge of ecosystem response to eutrophication and management of eutrophication in different marine fjord ecosystems and zones in Norway and Chile. The outcome of the field studies will be the determination of the most pronounced chemical and bioindicators of eutrophication in different conditions; this knowledge will give us the ability to improve monitoring activities in the future for early detection and management of the eutrophication problem.
