The purpose of this Work Package is to examine the various approaches to analysing fishery exclusion zones (FEZs) and to identify the circumstances in which one approach might be preferred to another. Our concern here is not so much with answering questions about exclusion zones - these being dealt with in later Work Packages - as with articulating the questions themselves and in understanding how in principle they could be addressed. An important theme is the precision with which questions need to be answered, since this will determine the type of information collected and how such information is analysed. The question ' is an exclusion zone likely to improve the condition of this fishery ?' is less precise and less demanding of data than the question ' by how much will an exclusion zone improve this fishery ?' since it could in principle be answered by expert judgement rather than quantitative analysis. In practice fisheries managers may be confronted with situations where decisions have to be made quickly, and qualitative answers may be the only thing possible in circumstances where data cannot be obtained in the available time. The Work Package will look at FEZs from a number of different perspectives, but its dominant concern is with the information – principally in the form of socio-economic and biological indicators - needed by fisheries managers in order to evaluate the effectiveness of FEZs. To contextualise the discussion we start by outlining a paradigm for understanding the linkages between human activities and the environment, showing how it can be applied to fisheries and marine resources. The Work Package then considers the substantive information requirements of fisheries managers, commencing with socio-economic assessment and moving on to a review of biological assessment and the progress which has been made in the development of mathematical models of FEZs. Bio-economic modelling, which is essentially a specialised type of socio-economic assessment in which explicit account is taken of the interaction between the biological and economic components of the fishing system, is dealt with in the final section.
