Abstract
Different measures of capacity utilization (CU) are applied to the Danish Gillnet fleet using the Data Envelopment Analysis (DEA) approach. The potential capacity output is found using the output-orientated measure. The CU measures are the partial capacity utilization measure and the Ray measure (DEA measure). The average CU of the Danish Gillnet fleet was found to be between 0.85 and 0.95 depending on the measure used. Since the Danish Gillnet fleet participates in a multispecies fishery regulated by TACs (output) the excess capacity was also found for each species. The results show higher excess capacity for cod and sole than for other species, which is in accordance with how the fishery developed. The variable input utilization was also estimated. On average, the variable input could have been increased by 27 percent in the period examined. Finally, the results are interpreted with respect to fishing area, port, vessel size and catch composition.
