摘要

海鲜产品消费量的不断增长引发了人们对海洋生态系统可持续性的担忧。我们研究了海鲜需求对渔业可持续性的影响。我们的分析依赖于一个生物经济模型，该模型结合了由 CES 效用（取决于不同鱼类物种）衍生的需求、基于 Schaefer 生产函数的混合渔业供给、市场均衡和基于多物种资源的动态变化。利用稳态方法和生物经济可行性目标，我们确定了需求特征的分析条件，使生物多样性保护与可行利润之间的平衡成为可能。我们以法属圭亚那的沿海渔业和海产品系统为例说明了分析结果。

From fork to fish: The role of demand on the sustainability of multi-species fishery

The increasing consumption of seafood products raises concerns over the sustainability of marine ecosystems. We examine the role of seafood demand on the sustainability of fisheries. Our analysis relies on a bio-economic model combining a demand derived from a CES utility depending on different fish species, a mixed fishery supply based on the Schaefer production function, a market equilibrium and a multispecies resource-based dynamics. Using both a steady-state approach and bio-economic viability goals, we identify analytical conditions on demand features making it possible to balance biodiversity conservation with viable profits. We exemplify the analytical results with the coastal fishery and the seafood system in French Guiana.

期刊介绍： Ecological Economics is concerned with extending and integrating the understanding of the interfaces and interplay between "nature''s household" (ecosystems) and "humanity''s household" (the economy). Ecological economics is an interdisciplinary field defined by a set of concrete problems or challenges related to governing economic activity in a way that promotes human well-being, sustainability, and justice. The journal thus emphasizes critical work that draws on and integrates elements of ecological science, economics, and the analysis of values, behaviors, cultural practices, institutional structures, and societal dynamics. The journal is transdisciplinary in spirit and methodologically open, drawing on the insights offered by a variety of intellectual traditions, and appealing to a diverse readership. Specific research areas covered include: valuation of natural resources, sustainable agriculture and development, ecologically integrated technology, integrated ecologic-economic modelling at scales from local to regional to global, implications of thermodynamics for economics and ecology, renewable resource management and conservation, critical assessments of the basic assumptions underlying current economic and ecological paradigms and the implications of alternative assumptions, economic and ecological consequences of genetically engineered organisms, and gene pool inventory and management, alternative principles for valuing natural wealth, integrating natural resources and environmental services into national income and wealth accounts, methods of implementing efficient environmental policies, case studies of economic-ecologic conflict or harmony, etc. New issues in this area are rapidly emerging and will find a ready forum in Ecological Economics.
