摘要: Efficiency analysis in fisheries has become an area of increased research. However, setting up models to perform such analyses is complicated and several important modeling issues, including choice inputs outputs, level aggregation inclusion stock indices, have only briefly been addressed the literature. The latter issue this paper, using data on Danish seiners Data Envelopment Analysis (DEA) estimate efficiency. Production obviously dependent fish stocks, comparing vessel efficiency, therefore, needs account for developments. Three methods include stocks are analyzed. It shown that estimations based Catch Per Unit Effort (CPUE) measure differ from independent measures, time horizon input/output measures.
