Abstract

Overfishing continues to drive the decline of sharks and rays worldwide, contributing to the deterioration of their global conservation status. Effective fisheries management can prevent overfishing, but only a small fraction of the global catch of sharks and rays has been assessed as being sustainable. A weight‐of‐evidence stock assessment framework, incorporating many stock‐specific analyses, is used herein to provide scientific advice and inform the management and conservation of shark and ray species (n > 100) that interact with fisheries in Western Australia, a global shark and ray diversity hotspot. The rigorous management regime implemented in Western Australia over the last four decades effectively reduced fishing mortality. The current fishing sustainability risk for most species is low, with previously overfished stocks recovered or recovering to sustainable levels. Our study provides optimism and confidence that the application and implementation of effective management arrangements can recover shark stocks and thereby underpin sustainable fishing operations.

多年管理确保全球鲨鱼生物多样性热点的高可持续性和低风险

过度捕捞继续导致世界范围内鲨鱼和鳐鱼的数量减少，导致其全球保护状况恶化。有效的渔业管理可以防止过度捕捞，但据评估，全球鲨鱼和鳐鱼的捕捞量中只有一小部分是可持续的。本文采用证据权重种群评估框架，结合许多种群具体分析，为与西澳大利亚州渔业相互作用的鲨鱼和鳐鱼物种（n > 100）的管理和保护提供科学建议，西澳大利亚州是全球鲨鱼和鳐鱼多样性热点。过去四十年来在西澳大利亚实施的严格管理制度有效地降低了捕鱼死亡率。目前大多数物种的捕捞可持续性风险较低，以前过度捕捞的种群已恢复或正在恢复到可持续水平。我们的研究提供了乐观和信心，即有效的管理安排的应用和实施可以恢复鲨鱼种群，从而支持可持续的捕鱼作业。

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.
