Within the framework of the research and technological progress (IRN BR2359l 095), the project: “Modeling the state of stocks in inland commercial waters with the development of a software package and domestic methodological recommendations for accounting for the number of fish and calculating the maximum permissible catch” TOO “Company of systems research “Factor” is developing an information system for calculations and assessment of fish stocks.

Today, the general director of TOO “Company of systems research “Factor”, candidate of physical and mathematical sciences Gabbasov Mars Bekkalievich held an online seminar on the topic: “Annual multi-species cohort mathematical models for assessing stocks of fish resources”.

The seminar considered:

1. Mathematical modeling of stocks;
2. Single-species difference model of Schaefer;
3. Multi-species difference model of Schaefer;
4. Multi-species model for age groups;
5. Multispecies cohort model for each age of fish;
6. Mutual influence of fish species;
7. Equations for predatory fish species for a dynamic model;
8. Equations for predatory fish species for a semi-dynamic model;
9. Influence of environmental factors.
