The reality of fish as both a scarce resource and a public resource has meant that the practice of fishery management always involves the balancing of multiple objectives. This is a long-standing truth, though one not necessarily incorporated into conventional fishery economics analyses, such as those focused on rent maximization. This chapter highlights the shift to a bio-socio-economic framework that links bioeconomic and socio-economic approaches to fishery analysis. It describes two specific examples of bio-socio-economic analysis, based on model frameworks- one involving a combination of multiple objectives and labour dynamics, the other the dynamics of fishing communities and the nature of distributional impacts. The chapter then turns from model-based analysis to fishery policy analysis, showing how a broader bio-socio-economic perspective can result in improved fishery policy. It talks about the future potential and role for fishery bio-socio-economics.
