Abstract

The paper reports the length–weight relationships of 3 species from the Poyang Lake, the largest freshwater lake freely connect to the Yangtze River, China. A total of 1,207 specimens were collected seasonally (January, April, September and November, 2010) using various types of fishing gear nets (mesh size: 1–12 cm) and stationary lift nets (mesh size: 0.7–4.4 cm). For each species, the sample size, length range, weight range, LWR, 95% confidence intervals of a and b, and coefficient of correlation were determined. Length-weight relationships for 1 species were unknown to FishBase, and new maximum lengths are recorded for 2 species.
