渔民们最清楚什么时候能识别出稀有和枯竭的鱼类品种？全球保护危机要求管理人员整理所有可用的数据集，为枯竭物种的保护管理计划提供信息，但对当地知识的信任程度仍然不确定。本研究比较了四种推断国际贸易的稀有和枯竭的海洋鱼类（海马属）物种分布的方法：使用（i）渔民访谈;（ii）政府研究拖网;（iii）科学潜水调查;（iv）公民科学贡献。我们分析了这四个数据集在属和单个物种的水平，以评估我们的结论海马的空间发生，物种多样性和采样工作的成本效益。我们发现，fisher的知识在更大的空间尺度上提供了更多关于我们缺乏数据的鱼类属的信息，并且比所有其他数据集更便宜。一个缺点是，渔民无法提供物种一级的数据。从事数据贫乏物种保护工作的人可能希望开始与渔民的访谈，并利用这些来告知政府研究，科学潜水或公民科学计划的应用。
Do fishers know best when it comes to identifying areas with rare and depleted fish species? The global conservation crisis demands that managers marshal all available datasets to inform conservation management plans for depleted species, yet the level of trust placed in local knowledge remains uncertain. This study compares four methods for inferring species distributions of an internationally traded, rare and depleted genus of marine fishes (Hippocampus spp.): the use of (i) fisher interviews; (ii) government research trawls, (iii) scientific diving surveys, and (iv) citizen science contributions. We analyzed these four datasets at the genus and individual species levels to evaluate our conclusions about seahorse spatial occurrence, diversity of species present and the cost effectiveness of sampling effort. We found that fisher knowledge provided more information on our data-poor fish genus at larger spatial scales, with less effort, and for a cheaper price than all other datasets. One drawback was that fishers were unable to provide data down to the species level. People embarking on conservation endeavors for data-poor species may wish to begin with fisher interviews and use these to inform the application of government research, scientific diving, or citizen science programs.
