摘要: Hucho taimen is also named taimen, belonging to Salmoniformes, Salmonidae, Hucho spp. With their ecological environment being damaged and resources being declined, resulting in the number of stocks decreased, then-state was endangered now (Dong 1998).Hucho taimen is a kind of indigenous cold-water fish with large body size and restrictediy distributed in Heilongjiang River and Eerqisi River of China (Holcik et al. 1988). The endangered status of taimen was re-evaluated in 2006. Based on the continuedeclines the taimen in Heilongjiang River Basin were moved from category III in 1998 to V in 2006 (Pronin 2006). Of the 20000 or so living fish species, the karyotypes of only 10% have been described (Gold 1979). In this paper, we present data on the metaphase chromosomes of Hucho taimen, a species in which the karyotype has not previously been published.
