  Citation × Citation Citation Abstract Copy Title: Physical Versus Harvest Based Measures of Capacity: The Case of the UK Vessel Capacity Unit System Author: Pascoe, Sean, Mardle, Simon, Coglan, Louise Year: 2001 The FAO International Plan of Action on the management of fishing capacity calls for all member states to provide estimates of the total capacity of their fleets by 2001. In the UK, a “capacity” measurement system is currently in place, based on vessel size and engine power. An assumption is made that this measure is related to the harvesting ability of the fleet, and is the basis of the existing capacity reduction programs. In this paper, the harvesting capacity of a sample of UK otter trawls and netter-liners is estimated using data envelopment analysis (DEA). Estimates are made on a species by species basis for the key species harvested. These are compared to the existing measures of physical capacity. Implications for capacity management based on the physical measures, given the results, are drawn.

This paper presents the definitions of harvesting capacity, excess capacity, and overcapacity used in the two reports; summarizes the method used to estimate harvesting capacity; and presents some of the findings and policy recommendations in the two reports. The National Assessment was used in preparing the Report to Congress. The Report to Congress includes harvesting capacity assessments for 25 fisheries, 60 fleets, and 127 species groups; identifies and described the fisheries with the most severe examples of excess harvesting capacity; and discusses measures to reduce excess harvesting capacity.

  Citation × Citation Citation Abstract Copy Title: Measuring Capacity of the New England Otter Trawl Fleet Author: Kirkley, James, Walden, John B. Year: 2001 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 technologicalengineering 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.

• 7. [Article] Capacity, Excess Capacity, and Fisheries Management

  Excess capacity results because fishermen do not have an incentive to conserve fish in-the-sea causing them to overinvest in the capital used to harvest fish as well as other production or factor inputs. ...

  Citation × Citation Citation Abstract Copy Title: Capacity, Excess Capacity, and Fisheries Management Author: Ward, John Year: 2001 Excess capacity results because fishermen do not have an incentive to conserve fish in-the-sea causing them to overinvest in the capital used to harvest fish as well as other production or factor inputs. Excess 1 capacity like overcapitalization and overfishing is a symptom of our regulated, open access fishery management system. Because capacity has been an ill-defined term in the fisheries literature, it has been poorly understood by fisheries managers. Excess capacity exists in a fishery when the yield from the fishery exceeds the point where net benefits to society are at a maximum; i.e., once maximum economic yield (MEY) is exceeded. Since MEY often occurs before maximum sustainable yield (MSY) is achieved in a developing fishery, excess capacity already exists in a fishery with a fully utilized fish stock. Even where barriers to entry exist in a fishery, such as exclusive economic zones (EEZs), permit moratoriums, or transferable licenses, fishermen who participate in the fishery retain a market incentive to race for the fish since no property rights exist for the in situ marine resource; i.e., the fish-in-the-sea. While the adverse effects of excessive capacity levels have become too obvious and severe to ignore,2 they can be corrected. With economically rational fisheries management, fishermen behave as if a private property right exists for the in situ marine resource. This creates a market incentive for fishermen to conserve the fish stock by divesting capital and other factor inputs needed to harvest fish until the yield from the fishery corresponds to MEY, the fish stock is conserved, and excess capacity in the fishery is eliminated. Achieving this objective is a matter of great debate. Without an unbiased and objective capacity measurement metric, the success or failure of regulations designed to reduce capacity cannot be accurately assessed.

Quentin, Squires, Dale, Dupont, Diane P., Kirkley, James Year: 2001 Using individual firm data from before and after the introduction of ITQs in the multi-species Nova Scotia mobile gear fishery, data envelopment analysis (DEA) is used to examine issues relating to capacity and capacity utilization. The paper examines how a change in the property rights regime can affect a multi-product industry and the consequences of these changes in terms of product-specific capacity utilization, as well as aggregate capacity utilization. The results provide insights to regulators interested in using market-based approaches to improve efficiency in multi-product industries.

There is, thus, a need to reduce harvesting capacity throughout many of the fisheries of the world. Yet, even the term capacity is not well defined, and it is even more complicated to measure. In this paper, we introduce several definitions and measures of capacity that are consistent with economic theory and empirical analyses. Since economic data on production activities are usually unavailable, we introduce the concept of data envelopment analysis (DEA) which may be used to calculate a physical or primal-based concept of capacity in fisheries. We initially introduce DEA and dispel many of the myths believed to be problems of DEA. We discuss how DEA may be used to calculate capacity in single and multiple-species fisheries.
