Descripción
The present document includes two papers on the measurement of fishing capacity and completes existing FAO documentation on this topic. The first paper is introductory and provides a general framework for measurement and assessment. Capacity analysis can indeed assist fisheries managers in obtaining more information on the underlying capacity issues of fishing fleets, in terms of efficiency, productivity and overall balance with available resources. The second paper presents a practi cal and illustrative application of these analyses in an empirical setting for the fishing industry. Many tools are available that can be readily applied to input/output data of fishing fleets. Five such approaches are considered in the context of economic theory, namely catch-per-unit-effort, variable input utilization, peak-to-peak, data envelopment analysis and breakeven analysis.
