A method is introduced and applied to analyse changed in productivity of firms harvesting in a multi-species fishery. The index-number technique decomposes firm profits into its contributions and can be used to assess economic performance by both regulators and individual firms across an industry and over time.

About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). Using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the...
Detailed economic analyses of fisher performance are critical inputs in improving the management of fisheries. The paper provides guidelines about the economic methodologies and the data required to monitor and assess the performance of individual transferable quota fisheries. In particular, it describes the methods of evaluation that could be applied...
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...
