Abstract
Abstract Mixed fisheries occur when multiple species are caught together and harvested by multiple fleets. The biological and technical interactions in mixed fisheries distinguish them from single-species fisheries, which makes them challenging for their assessment and management. The present knowledge synthesis reviewed pertinent policy documents and academic databases for twenty-three mixed fisheries worldwide; aiming to characterize attributes of mixed fisheries, provide overviews on their assessment and management, assess current research progress, and identify key factors that impact management effectiveness. Mixed fisheries were found to exhibit varying characteristics worldwide, rendering the implementation of universal management solutions unlikely. While mixed fisheries stock assessment and management are mostly based on single-species approaches, additional mixed fisheries considerations were incorporated at various scales, including multispecies, sector-specific, fishery, and ecosystem levels. Ecosystem-wide management considerations were the most significant contributor to improved management performance in terms of conserving stock biomass and preventing overfishing, underscoring the merits of the Ecosystem-based Fisheries Management (EBFM) principle. Mixed fisheries research demonstrated regional and thematic variations, with the most popular topics addressing immediate and practical management concerns, and the less frequently discussed topics offering valuable insights related to climate change and socio-ecological perspectives. The synthesis identified the available management approaches for mixed fisheries from different jurisdictions, yet their diversity highlighted a lack of global consensus on best management practices. Future mixed fisheries will benefit from balancing tradeoffs between ecological and socio-economic needs, implementing EBFM, adopting diverse and harmonized management tools, and prioritizing monitoring efforts.
期刊介绍:
Reviews in Fisheries Science & Aquaculture provides an important forum for the publication of up-to-date reviews covering a broad range of subject areas including management, aquaculture, taxonomy, behavior, stock identification, genetics, nutrition, and physiology. Issues concerning finfish and aquatic invertebrates prized for their economic or recreational importance, their value as indicators of environmental health, or their natural beauty are addressed. An important resource that keeps you apprised of the latest changes in the field, each issue of Reviews in Fisheries Science & Aquaculture presents useful information to fisheries and aquaculture scientists in academia, state and federal natural resources agencies, and the private sector.
