摘要： This study provides the length-weight relationships (LWRs) for four fish species [Leptobotia rubrilabris (Dabry de Thiersant, 1872); Opsariichthys bidens Gunther, 1873; Xenocypris yunnanensis Nichols, 1925; and Sinogastromyzon sichangensis Chang, 1944] collected from the Niulan River, China. Samples were obtained between April 2008 and June 2011 using various types of fishing gear [drift gill nets (mesh: 5x5cm), hook and electro fishing]. A total of 136 specimens belonging to four fish species were analyzed. For each species the sample size, length range, weight range, LWR, 95% confidence intervals of a and b, and coefficient of correlation were determined. Prior to this study, the LWRs for S. sichangensis and X. yunnanensis were unknown. New maximum sizes for S. sichangensis and X. yunnanensis are also provided.
