Economic impact assessment methodology was applied to UK fisheries data to better understand the implications of European Commission proposal for regulations to fishing for deep-sea stocks in the North-East Atlantic (EC COM 371 Final 2012) under the Common Fisheries Policy (CFP).

The cost of fishing and the income earned by fishers using small and large traps, gill nets, beach seines, hand lines, and spearguns were assessed in the multigear fishery of southern Kenya to establish a financial rationale for fishing gear use. Direct observations and key-informant interviews with fish leaders and boat captains were used to gather data on fish catch, cost of fishing gear, boats, and the price of fish. Among the fishing gear used, spearguns had the lowest monthly cost (USD 1 mo(-1)) while big traps had the highest (USD 13 mo(-1)).
