Riverine environmental characteristics and seasonal habitat use by adult Sakhalin taimen Hucho perryi.
The study identified seasonal habitat use by endangered adult Sakhalin taimen Hucho perryi and the environmental characteristics of their habitat (water depth, amount of riparian forest and sinuosity). Fifteen adult H. perryi with acoustic tags were tracked by towing an acoustic receiver with a canoe in the Bekanbeushi River system in eastern Hokkaido Island, Japan, during each month from late ...
متن کاملMitochondrial DNA Variation and Introgression in Siberian Taimen Hucho taimen
Siberian taimen Hucho taimen is the largest representative of the family Salmonidae inhabiting rivers of northern Eurasia. The species is under intensive aquaculture activity. To monitor natural taimen populations we have sequenced a portion (8,141 bp) of the mitochondrial (mt) genome in 28 specimens of H. taimen from six localities in the Amur River basin. Nucleotide variability is low (π = 0....
متن کاملSerum Immunoglobulin M (IgM) in Sakhalin Taimen (Hucho perryi): Purification, Characterization, Circulating Levels, and Specific IgM Production by the Parasitic Salmincola stellatus
Immunoglobulin M (IgM) was purified from the serum of Sakhalin taimen (Hucho perryi) by salting-out, ion-exchange chromatography on DEAE-cellulose, and gel filtration on Sepharose 6B. The intact, tetrameric taimen IgM has a mass of 750 kDa with molecular architecture typical of IgM from other salmonids. The molecular weights of heavy (μ) chain and light chains (L) of the IgM monomer were estima...
متن کاملPopulation genetic structure of taimen, Hucho taimen (Pall.), in China
Hucho taimen (Pall.) is one of the largest salmonid species, and has been classified as an endangered species in China since 1998. In recent years, its wild stocks, habitats, and spawning grounds have been severely damaged by environmental degradation and human intervention. To protect and exploit this treasured species effectively and sustainably, the genetic diversity and structure of taimen ...
