人为干扰在海洋中无处不在，但其对海洋物种的影响却引起了激烈的争论。我们使用养护(红色名单受威胁与否)和渔业(高于或低于参考点)指标来评估海洋鱼类状况，比较它们的排列，并诊断为什么会出现差异。虽然只有13.5%的红色名录海洋鱼类(n=2952)受到威胁，但进行种群评估的种群(n=166)中，目前分别有40%和21%的种群低于更保守和更高风险的参考点。养护和渔业指标很好地吻合(70.5%对80.7%)，尽管它们在数学上是分开的。红色名单并不偏向于夸大威胁状况，严重的错误--将种群归类到渔业和养护指标的相反极端--是罕见的。我们的分析表明，养护和渔业科学家将在大多数情况下就被开发的海洋鱼类的状况达成一致，只有共同关心的种群的适当管理对策问题仍未解决。
Anthropogenic disturbances are ubiquitous in the ocean, but their impacts on marine species are hotly debated. We evaluated marine fish statuses using conservation (Red List threatened or not) and fisheries (above or below reference points) metrics, compared their alignment, and diagnosed why discrepancies arise. Whereas only 13.5% of Red Listed marine fishes (n=2952) are threatened, 40% and 21% of populations with stock assessments (n=166) currently are below their more conservative and riskier reference points, respectively. Conservation and fisheries metrics aligned well (70.5% to 80.7%), despite their mathematical disconnect. Red Listings were not biased towards exaggerating threat status, and egregious errors, where populations were categorized at opposite extremes of fisheries and conservation metrics, were rare. Our analyses suggest conservation and fisheries scientists will agree on the statuses of exploited marine fishes in most cases, leaving only the question of appropriate management responses for populations of mutual concern still unresolved.
