To investigate the length-weight relationship and the condition factor of Brachymystax lenok according to climate change, the survey was conducted from June 2005 to October 2014 at the upper stream of Gyebang Stream in Hongcheon County, Gangwon Province for 3-4 times a year. As a result, a total of 1226 fishes of 2 species and 2 species appeared. The analyze of the annual regression coefficient (b) and the condition factor (K) of the B. lenok, the result as follows, in 2005, the value of b was 3.17, and value of K was 0.0012, and in 2014, the value of b = 2.83 and the value of K was 0.001. As a result of analyzing the yearly regression coefficient b of B. lenok together with the precipitation and temperature data of each year, the trend was decreasing year by year, and the two factors showed a positive correlation with each other. On the other hand, the temperature trend showed an increasing tendency year by year and correlated negatively with the annual growth of B.lenok. Overall, the B. lenok habitat upstream of the Gyebang stream appears to be becoming increasingly unstable each year, indicating that these factors are closely related to temperature and precipitation. In other words, a rise in temperature and a decrease in precipitation seem to have a negative impact on the population growth of B. lenok. These results may be important clues for future recovery and conservation of B. lenok populations. For this, it is necessary to monitor the B. lenok populations and temperature and precipitation continuously.
