The article presents the analysis of the development of commercial objects in the North-Kuril zone of the Far Eastern fisheries basin for a ten-year period. The resource potential of this zone was found to consist of 11 objects for which the total allowable catches were established (TAC objects) and of 4 objects, the extraction of which is carried out within the recommended volumes (non-TAC objects). The main objects of production in the North-Kuril zone were pollock, Commander squid and terpug, the production volumes of each species, in the total catch of all objects, amounted to 48, 26 and 13%, respectively. The production volumes of the rest commercial objects amounted to a total of about 13%. An analysis of the dynamics of changes in the TACs was carried out for each test fishing object. A decrease of catch volumes in 2019, compared to 2010, was observed in three objects: terpugs, halibut and macrurus. For these objects during the period under review there was found a decrease in TAC volumes. Analysis of the development of the objects under study during the period 2010-2019 showed that crabs, scallops and pollock in the studied time interval had consistently high catch volumes and a high degree of development. The average rate of development of these objects was about 90% or more. The remaining 8 fishing objects were under-developed annually. The average degree of development of Far Eastern flounder, Commander squid, terpug, cod, sea bass was about 55-75%. The lowest average rate of development (less than 50%) was observed in halibut, pinchback and macrurus. It has been inferred that it is necessary to conduct further studies of fishing activities to develop the resource potential for subsequent modeling and optimization of fishing processes
