The Implications of Environmental NGO Involvement in Fisheries Management

Margrethe Aanesen and Claire W. Armstrong


What happens when an environmental NGO (ENGO) becomes involved in fisheries management, and its involvement is recognized by the managing authorities? The answer depends on the preferences and the measures of the ENGO. We use a bioeconomic objective function where fishers and regulator have ecological, economic, and social preferences, whereas the ENGO has only ecological preferences. Applying a Cournot model we analyze how the original regulation of the authorities is affected when an ENGO becomes involved. We use empirical data on fisheries stakeholder preferences and from the Portuguese and Spanish sardine purse seine fishery to calibrate and test the model. (JEL Q22, Q28)
