[email protected] Abstract. The present paper summarizes a large part of the endangered and critically endangered fish species of the world. The list was constructed using the comprehensive IUCN Red List of Threatened Species (available in December 2008) and the well elaborated FISHBASE (available on the official website, in 2008) for taxonomy and accepted scientific names of the species. To these two important sources, many scientific papers and communications were added when recent and useful reports were found. However, there is a long way from the fish species list of this review to the world’s complete list of endangered and critically endangered fish species. In our list were not included subspecies, populations, varieties, or species having a debatable taxonomic status. The scope of this review was not to inventorize all the fishes included in these two categories, but to make possible drawing some general conclusions regarding most important possible causes of fish species extinction and to make suggestions concerning fish species conservation possibilities through aquaculture. Key Words: endangered fish species, critically endangered, causes, population trend.
