As a result of the evaluation of the indicators of a large fishing enterprise of the Volga-Caspian basin (carrying out extraction and processing of biological resources), proposals were presented to reduce the value of the property and sources of financing of the organization, and this decrease was generally balanced with changes in revenue and profit of the enterprise. Considering the results of the analysis, as well as external and internal factors of the organization’s functioning, it is recommended to create a planning system to ensure financial stability in subsequent periods. Implementation is possible with the organization of the budgeting process. A stock management strategy was proposed to optimize their volume and structure. ABC analysis was used for this purpose, which made it possible to strengthen control over the main types of stocks and improve management efficiency. The proposed measures will facilitate the release of funds and contribute to the stabilization of the financial condition of the enterprise.
