Спецпереселенцы на Урале в 1930-е гг.: генезис и динамика региональной подсистемы принудительного труда
The method of econometric analysis is proposed that allows to study the influence of water resources quality on fish productivity in water bodies of fisheries import. The system of metrics is formed that facilitates optimization of the branch activity monitoring and makes it possible to explore, guiding by existing hydrochemical and hydrobiological resources of water bodies, the factors responsible for shaping the trajectory of the branch sustainable development. Basing on these considerations, the prognostic model is proposed that can predict fish productivity with higher precision as compared with the available analog. Using the Urals lakes as an example, it is shown that currently executed poor water-management system does not allow proper resources exploitation and aquaculture planning in water bodies of fisheries import.
