The biological peculiarities of the Arctic cisco in the western part of its natural range were determined on the basis of the study of many years (Pechora flock). The size-weight structure, growth speed and sexual composition of the fatting flock were determined. The sexual maturity age and condition of the gonad’s maturity phases by the formation of the spawning flock were fixed. Its biological characteristic during the period of the spawning run in the low flow of Pechora and at the natural spawning locations in Usa was done. The anthropogen factors which influent negative the Pechora Arctic cisco flock were considered. These results can be used by the elaboration of the general strategy of rational white fish species use in this region. ...
