The Salmonid fishes of Lake Baikal and its adjacent water systems: annotated checklist with new taxa description

Abstract

Abstract. The updated list of Salmonid fishes of Lake Baikal and its adjacent basins is presented with data on nomenclature, diagnostic characters and distribution, systematics notes and illustrations. At present, 20 species of salmon-like fish belonging to eight genera and three families (Coregonidae, Salmonidae and Thymallidae) have been indicated in the Baikal region. The validity of the species Coregonus skrjabini Karasjov, 1987; Coregonus sajanensis Gundriser, 1978 and Brachymystax czerskii Kirillov, 1979 has been restored. A new replacement name Coregonus karasjovi Bogdanov (nom. nov.) has been established for Baunt cisco-liked whitefish. A new species of grayling Thymallus lenensis Knizhin (sp. nov.) has been described.

Thermal Preconditioning Alters the Stability of Hump-Snout Whitefish (Coregonus fluviatilis) and Its Hybrid Form, Showing Potential for Aquaculture

“…A similar situation has recently developed for whitefishes in the Baikal-Yenisei basin. In particular, Yenisei hump-snout whitefish (Coregonus fluviatilis Isaczenko, 1925) [40][41][42], inhabiting Lake Baikal and previously classified as Baikal pidshian (C. pidshian Gmelin, 1877) [37,43,44], is currently in an extremely stressed state, to the point of complete extinction due to anthropogenic pressure [43,45].…”

“…Since whitefish fisheries in many lakes and reservoirs are declining and unable to meet market demand, the challenge of developing highly productive aquaculture of this species using knowledge-intensive technologies is particularly urgent [43]. The hybrid of Yenisei hump-snout whitefish with Baikal whitefish (C. baicalensis Dybowski, 1874) [40,41] are also considered as promising from the perspective of commercial production [43]. In particular, the hybrids obtained by artificial insemination (included the use of cryopreserved sperm) showed a good growth rate in aquaculture conditions and can be considered as promising for further cultivation, although there are no data on the stress resistance and stability of these forms.…”
