We evaluated growth, mortality, and resource utilization of burbot, Lota lota, in the upper reaches Heilongjiang River, China. The population has experienced significant decline, and, despite substantial recovery, concerns regarding management have arisen. A total 638 specimens collected from October 2022 to 2023 were used calculate relationship between body length weight, which ranged 107 529 mm 8.91 1474.17 g, respectively. FAO FiSAT II software was estimate parameters based on frequency distribution samples. calculated progressive value growth coefficient 551.25 0.16, natural mortality rate burbot is 0.31 a−1.
