Assessment gaps and biases in knowledge of conservation status of fishes

摘要: More than 33,500 fish species inhabit freshwater and marine environments, according to FishBase database records. The International Union for the Conservation of Nature (IUCN) has assessed conservation status approximately half them, lowest percentage in any vertebrate group. In order identify what factors may underlie this assessment gap, several traits were examined related distribution, life‐history, taxonomy, conservation, economic relevance their status. IUCN patterns explored separate analyses included species. The results showed that assessments biased towards economically developed regions, with early description dates covered by current specialist groups. Species living remote areas or habitats more likely be unassessed. In particular, South America had low levels. Other such as commercial importance did not influence species. We therefore encourage poorly taxonomic subgroups prompt timely action prevent extinctions.
