Species, space and time: A quarter century of fishers' diversification strategies on the US West Coast
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.
期刊介绍：
Fish and Fisheries adopts a broad, interdisciplinary approach to the subject of fish biology and fisheries. It draws contributions in the form of major synoptic papers and syntheses or meta-analyses that lay out new approaches, re-examine existing findings, methods or theory, and discuss papers and commentaries from diverse areas. Focal areas include fish palaeontology, molecular biology and ecology, genetics, biochemistry, physiology, ecology, behaviour, evolutionary studies, conservation, assessment, population dynamics, mathematical modelling, ecosystem analysis and the social, economic and policy aspects of fisheries where they are grounded in a scientific approach. A paper in Fish and Fisheries must draw upon all key elements of the existing literature on a topic, normally have a broad geographic and/or taxonomic scope, and provide general points which make it compelling to a wide range of readers whatever their geographical location. So, in short, we aim to publish articles that make syntheses of old or synoptic, long-term or spatially widespread data, introduce or consolidate fresh concepts or theory, or, in the Ghoti section, briefly justify preliminary, new synoptic ideas. Please note that authors of submissions not meeting this mandate will be directed to the appropriate primary literature.
