Abstract
Since 2022, the possibility of trawl fishing on Khanka Lake has been opened. In 2018 and 2020, accounting work was carried out using a beam trawl. Studies have shown that the highest biomass in trawl catches was far eastern freshwater shrimp (Palaemon modestus), noodle fish, sharpbelly, bagrid catfish and humpback. According to the trawl survey, the stocks of shrimp and small fish species amounted to 3,5–4,6 thousand tons. Taking into account the underestimation of these biological resources during the performance of work, the resource base can be at the level of 14,0–15,0 thousand tons.
