Dealing with dynamics and uncertainty of small pelagic fisheries: bioeconomic analysis of manager’s responses to alternative management strategies

Small pelagic fisheries have been characterized by large fluctuations in abundance due to environ mental factors, harvest regimes, and reproduction patterns, among others. Given this complexity, the development of management schemes for sardine fisheries requires an evaluation of the impact of diffe...
