Measuring Capacity and Capacity Utilization in fisheries: The Case of the Danish Gill-net Fleet


Measuring Capacity and Capacity Utilization in fisheries: The Case of the Danish Gill-net Fleet By Niels Vestergaard, Dale Squires and Jim Kirkley ABSTRACT Different measures of capacity utilization (CU) are applied to the Danish Gill-net fleet using the Data Envelopment Analysis (DEA) approach. The potential output is found using the output-orientated measure. The CU measures are partial capacity utilization, an aggregate output measure and the Ray measure. Problems of aggregation over area, species, fishing periods and vessels are discussed. The CU of the Danish Gill-net fleet is between 0.8 and 0.9. Since the Danish Gill net fleet participates in multispecies fisheries regulated by TACs (output) the results are tested by allowing different settings of TACs, e.g. setting of "target" TACs. The measure used here in the input-orientated. Finally the results are interpreted with respect to fishing area, port, vessel size and catch-composition.
