Abstract:
The biological foundations of the principle of mathematical modeling in fish farming were formulated in the middle of the last century. It was used as a mathematical representation of the quantitative aspects of the course of a biological process, such as the dynamics of the number of herds, the dynamics of population biomass and so on. In fish farming, mathematical modeling has been actively used in the last 30-40 years, especially with the development of computer technology.
The main directions were modeling of technological processes in fish farming in artificial conditions, but the main part of the research was focused on traditional objects of commercial cultivation - carp and salmon, while the use of this analysis tool in sturgeon farming is not widespread and existing models reflect the state natural populations of sturgeon. Special researches were carried out for 10 years on the basis of production and experimental Dnieper sturgeon fish factory. The material of the research was free embryos and larvae of the Russian sturgeon of the Dnieper population, obtained at the plant.
The obtained equations, in our opinion, can be used as a basis for planning the cultivation of larvae of Russian sturgeon to the viable stages in the pools, allow to predict the final indicators of average weight and survival for certain parameters of cultivation. Along with the obtained positive, there is an obvious need to continue research aimed at forming mathematical models of technological processes for all species of sturgeon with the inclusion in the analysis of the maximum possible number of biotic and abiotic parameters of the environment, which will significantly increase the reliability of modeling and forecasting.
