Marine Stewardship Council (MSC) certification is based on an assessment of a fishery’s performance against three levels within the MSC Fisheries Standard: ‘minimum acceptable’, ‘best practice’ and ‘state-of-the-art’. Determining the criteria that define these performance levels in the MSC Fisheries Standard is a challenging task. This is due to factors including the constant evolution of management practices that are used as benchmarks for each performance level, the broad nature of the MSC Fisheries Standard which must be applicable to all fisheries regardless of scale or intensity, and differing perspectives of stakeholders. Periodic review and updating the MSC Fisheries Standard ensure that certification keeps pace with global fisheries management. An area where the performance levels within the MSC Fisheries Standard were suspected to have lagged global management was in relation to shark finning. This study provides a global summary of management measures to minimise shark finning, an overview of information used to determine appropriate performance levels to assess shark finning, and the decision processes that led to changes in the revised MSC Fisheries Standard. The key changes are 1) a fins naturally attached (FNA) measure being required for all MSC certified fisheries that retain sharks, as FNA is now considered a global ‘minimum acceptable’ performance level, and 2) an MSC default definition for ‘sharks’ being Selachimorpha and Rhinopristiformes. In combination with other aspects of the MSC Fisheries Standard, the revised requirements represent a significant step forward to ensuring that shark finning does not occur in MSC certified fisheries.

如何制定适合 MSC 认证的性能水平？评估鱼翅的案例研究

海洋管理委员会 (MSC) 认证基于根据 MSC 渔业标准中的三个级别对渔业绩效进行评估：“最低可接受”、“最佳实践”和“最先进”。确定 MSC 渔业标准中定义这些性能水平的标准是一项具有挑战性的任务。这是由于以下因素造成的：用作每个绩效水平基准的管理实践的不断演变、MSC 渔业标准的广泛性（无论规模或强度如何）必须适用于所有渔业，以及利益相关者的不同观点。定期审查和更新 MSC 渔业标准可确保认证与全球渔业管理保持同步。 MSC 渔业标准中的绩效水平被怀疑落后于全球管理的一个领域与鱼翅有关。本研究提供了最大限度减少割取鱼翅的管理措施的全球摘要，概述了用于确定评估鱼翅的适当绩效水平的信息，以及导致修订后的 MSC 渔业标准发生变化的决策过程。主要变化是 1) 所有 MSC 认证的保留鲨鱼的渔业都需要采取鳍自然附着 (FNA) 措施，因为 FNA 现在被认为是全球“最低可接受”的性能水平，以及 2) MSC 对“鲨鱼”的默认定义是鲨鱼目和犀角目。与 MSC 渔业标准的其他方面相结合，修订后的要求代表着在确保 MSC 认证的渔业中不发生鱼翅事件方面向前迈出了重要一步。
