Abstract
The aim: The approbation of underwater imaging for G. lacustris counting in the under ice layer of fishery water body at the Beloe Lake as an example.
Methods: The method of underwater imaging was used to account G. lacustris inhabiting the bottom side of the ice cover and caught there into the frames of the counting zone which was determined on diameter of the hole from the manual fishing ice-drill. The biomass of G. lacustris in the biotope was calculated by multiplication of average number of individuals per unit area, determined from video recordings, by the average mass of one individual. Individuals for biomass determination were taken from the counting holes by the first release of individuals onto the ice during drilling of the hole.
Novelty: The method of G. lacustris counting based on underwater imaging is novel.
Results: Data on population density and biomass of G. lacustris in the Beloe Lake in April 2025 were obtained. It was established that the density of G. lacustris in the under-ice layer varied from 0 to 1960 ind. m‑2 (on average – 314±110.7 ind. m‑2). With an average weight of one individual of 0.047 g, the biomass of G. lacustris per unit area is 14.8 g m‑2, and in the under ice layer of the shallow zone of the lake is 5.9 tons. Taken into account the lower limit of standard error of density the biomass is 3.8 tons.
Practical significance: The proposed method can be implemented in the practice of determining the stocks of G. lacustris in commercial (fishery) water bodies, as well as for the purpose of monitoring the population of this species in water bodies with different characteristics.
