| Summary: | Distribution of the altay osman in one of the lakes of Mongolia was studied in summer. Indications of the sonar GPSMAP 178 were fixed withdigital camera. Analysis of fish horizontal distribution had shown that the maximal concentrations and minimal variability of fish density were registered in the areas with depths of 6–15 m. Analysis of vertical distribution of pelagic rarefied fish aggregationshas revealed two fish concentration zones (2–4 m and from 10 m to deeper). Between those zones the fish scores were sparse. On the contrary, dense aggregationsof fishes locate at the middle water strata in the core. |
