- Аннотация: Abstract Reproduction of the lacustrine-riverine form of the Drjagin charr (genus Salvelinus) from Lake Lama (the Noril’sk-Pyasina aquatic system on the Taimyr Peninsula) in a mountain tributary, the Bunisyak River, as well as the formation and development of skeletal elements in embryos and larvae reared under different experimental conditions are described. Patterns of the development and the heterochrony between the rates of somatic growth and osteogenesis are an adaptation to the extremely low water temperature and oligotrophic spawning habitat of the mountain stream. Still, the formation of vertebral centrae is retarded even at rather high rearing temperatures. As compared to larvae of the small normal (nondwarf) planktivorous lacustrine form of Arctic charr from Lake Davatchan (Transbaikalia) reared at 3°C, larvae of Drjagin charr from Lake Lama reared at 1°C are characterized by accelerated growth and heterochronies of osteogenesis. The divergence of the lacustrine-riverine form of Drjagin charr from the generalized form of Salvelinus alpinus in morphology begins during the larval period of the ontogeny.
