This article examines the development of aquaculture in small lakes. The landscape-dependent limnogenesis and limiting factors for fish farming are analyzed through the case of the small Lake Lesnoye (Vologda Region) as a model reservoir typical of widespread mid-boreal landscapes. The lake’s genesis, morphology, evolution, and current state have been determined by the region’s location in the north-western ice sheet margin. Having comprehensively studied this model reservoir, we identified key indicators of processes of both natural and anthropogenic nature unfavorable for fish farming. It is shown that the shallowness of lakes located in low-lying wet areas stimulates their succession towards humification, dystrophication, soil acidification, algal blooms, deterioration of the gas regime, low feeding capacity and formation of perch and roach dominated communities. The results of the model lake study can be approximated for other water bodies in this type of landscape, allowing for appropriate selection and planning of water resources to be used in aquaculture. The aim was to identify the limitations for aquacultural use of small water bodies through the case study of Lake Lesnoye as a model typical of widespread mid boreal landscapes, and to substantiate a methodological research algorithm within the landscape-ecosystem approach.
