Аннотация

The northern fur seal (Callorhin usursinus), inhabiting North Pacific, has long been a valuable commercial target. This work continues a series of studies aimed at analyzing the dynamics and reproductive characteristics of the northern fur seal population on the Tyuleniy Island. The paper provides analyzes of intrapopulation parameters influence on the population sex ratio and pups production.
