An evaluation of the opportunities and impediments in managing quota fisheries for biodiversity

摘要: Emerging political, ecological, and social priorities support inclusion of biodiversity conservation on national research management agendas. Meeting objectives, however, will be difficult for fishery systems that traditionally rely the single-species, single-population "stock concept". My dissertation examines four scientific institutional challenges to broadening scope fisheries include controlling impacts biodiversity. First, despite broad recognition its importance in ecosystems, there is no single definition can used tactical management. I recommend extending single-species approaches diversity within populations across space as a first step toward biodiversity-based Second, many existing data collection programs are not structured account spatial fish populations. use case Pacific herring (Clupea pallasi) Strait Georgia, British Columbia, illustrate how monitoring program designed estimate biomass spatially population generates vulnerabilities opens system disputes over conservation.
