Abstract [en]

The U.S. National Marine Fisheries Service has undertaken to measure the economic performance of fisheries that have implemented catch shares as a management strategy. Among the metrics used, change in productivity was identified as important, and considerable research has been conducted to construct metrics and to measure this change. We introduce the Bennet-Bowley (BB) indicator as another tool to measure change in productivity, show how to construct the indicator, and apply it to the northeast multispecies fishery, which adopted a catch share system in 2010. The BB indicator is then used to show the contribution of vessels entering, continuing within, and exiting the fishery to overall fleet productivity. Results showed that after catch share management, fleet productivity declined and that vessels continuing in the fishery as a group contributed the most to a decline in aggregate productivity. On a per-vessel basis, a core group of vessels continuing in the fishery and that were present throughout the study period showed a decline in productivity after catch share management was implemented. These declines were caused by reduced outputs (i.e. catch) in relation to use of inputs (e.g. labor, fuel, materials) after catch shares were implemented.
