The article contains the results of tectonogeodynamic paleoreconstructions and numerical spatio-temporal basin modelling, which allowed to reveal the structural features and formation conditions of the base of the Far Eastern seas of the Russian Federation, as well as the occurrence of crystalline protrusions in the pre-Cenozoic bases at the stage of prototectonics and posthumous tectonics, which are primarily due to heterogeneity of the viscous properties of various layers of the earth’s crust, i.e. its tectonic and material stratification. A large-scale lateral redistribution of the substance, its outflow out of the areas of increased compression and injection into areas of geodynamic shelters has taken place at this stage. Mechanisms of the formation of a void space within protrusions have been considered. A conceptual model of the formation of petroleum deposits within the granite massifs of the base has been proposed.

The article proposed to discuss a concept of new strategy for the sustainable use of populations of aquatic organisms using as an example a fishery for Walleye Pollock in the Far Eastern seas of the Russian Federation. It is shown that the current regulations governing the impact of fishing contained in the Fishing Regulations do not quite consider changes related to the dynamics of pollock populations parameters. As a result, there is an uncontrolled and often negative impact of fishing, which leads to changes in the phenotypic and size-age structure of W. Pollock populations being fished, which ultimately affects the profitability of fishing. It is proposed to develop a separate strategy for each W. Pollock stock unit, which annually regulates the level of fishing impact, depending on the state of the stocks and market conditions. The proposed strategy concept makes it possible to regulate not only the allowable volume of catch, but also the size structure of catches, by changing the fishing parameters every year. It will keep the harvested stocks stable and will help to obtain the maximum possible fishing profitability.
