Measuring Capacity of the New England Otter Trawl Fleet
Measurement of capacity in marine fisheries is an important activity.
An economic definition of capacity is the output level corresponding to
the tangency between the long-run and short-run average cost curves. A
technological-engineering definition is the maximum output per unit of
time provided variable inputs are unrestricted. Although cost data to
support an economic measurement of capacity in fisheries are not routinely
available, data are typically available to support the technological engineering
measure of capacity. Our paper provides an assessment of the technological-engineering
concept of capacity in the New England multispecies otter trawl fishing
fleet. Based on Färe et al. (1994), we calculate capacity using Data
Envelopment Analysis (DEA), a non-parametric technique which utilizes
linear programming methods to evaluate the performance of individual firms.
DEA is ideally suited to assess capacity in fisheries because it easily
accommodates multiple output-multiple input technologies. The New England
otter trawl fleet was used as a study fleet because it has a multi-product
nature, and is comprised of a wide variety of vessel types and sizes.
