Year: 2025
Type: article
Abstract: 3D phase portraits of the dynamics of the Yenisei sturgeon are presented and their connection with Kondratiev Waves is shown. Morphometric features are considered – the proportions of the heads and the types of coloring. The photo of Chelbash is given. The dependence of the proportion of the snout on the length and age for Amur, Ob and Yenisei sturgeons is constructed. An estimate of the proportion of sturgeons of extreme size is given. The Pennet table for the Yenisei sturgeon is given , matrix of fitness functions of the Costicin system λ.
