Diversification within fisheries operations can serve as an important form of self-insurance against natural, regulatory and market risks to fishers' livelihoods. Diversification can take many forms, and yet the literature has primarily emphasised diversification across species to the exclusion of spatial and temporal dimensions of diversification. We analyse trends in diversification across species, space and time for all fishers along the entire continental West Coast of the United States from 1990 to 2015. Our findings reveal the importance of untangling both compositional (i.e. driven by changes in fleet composition) and individual (i.e. driven by within-owner changes in diversification strategies) dimensions of diversification by showing how these effects have moved in contrary directions for all three forms of diversification. We also demonstrate how increases in temporal diversification have overwhelmed the overall stability of species and spatial diversification to leave the current fleet less exposed to financial variability compared to in the early 1990s.

物种、空间和时间:美国西海岸 25 年的渔民多样化战略

渔业作业的多样化可以作为一种重要的自我保险形式,以应对渔民生计面临的自然、监管和市场风险。多样化可以采取多种形式,但文献主要强调跨物种的多样化,而排除了多样化的空间和时间维度。我们分析了 1990 年至 2015 年美国整个大陆西海岸所有渔民在物种、空间和时间上的多样化趋势。我们的研究结果揭示了理清组成(即由船队组成变化驱动)和个体(即由所有者内部变化驱动的多元化战略)多元化的维度,通过展示这些影响如何在所有三种形式的多元化中朝着相反的方向移动。
