Length-weight relations (LWR) of six fish species from Geum, Nakdong and Yeongsan rivers in South Korea was estimated. A total of 5,152 specimens were measured and weighed. The linear relationship of total length and total weight were highly correlated for all species. No previous information on LWRs on Rhinogobius brunneus species were found in Fishbase. fyke, casting, gill, trammel net and fish traps. The whole body wet weight of fishes was measured by a digital weighing balance to the nearest 0.01 g accuracy and the total length (TL) was measured by a digital slide calipers to the nearest 0.01 cm.The relationship of length-weight was determined by W = aL b (Ricker, 1968). Where "W" is the body weight of the fish, "L" is the total length, "a" is the intercept of the regression curve and "b" is the regression coefficient. | RESULTSA total six species were studied during this study. A statistical description of the length-weight relationship is given in Table 1. The weight of the fish species is highly influenced by its length. All length-weight parameters are highly significant with all R 2 values (0.59-0.98).
