Abstract
In this study, the length-weight relationships were determined for four fish species of the upper Yangtze River, Sichuan province, China. The fish were collected by drift net (mesh size: 4 cm × 4 cm) and ground bamboo cages (1 cm × 1 cm) from Yalong River, Laixi River, Pingtung River, and Baoxing River. Samples were collected from March 2017 to December 2022. According to the length-weight function equation (
W
=
a
L
b
), r2 values ranged from 0.960 to 0.991 and the b values of LWRs ranged from 2.916 (Megalobrama pellegrini) to 3.095 (Claea dabryi).
本文对四川长江上游4种鱼类进行了长度-重量关系的研究。采用漂网(网目尺寸:4 cm × 4 cm)和落地竹笼(网目尺寸:1 cm × 1 cm)在雅砻江、莱溪河、屏东河和宝兴河进行采集。样本采集时间为2017年3月至2022年12月。根据长度-权重函数方程(W = a - L - b)， r2值为0.960 ~ 0.991,LWRs的b值为2.916 ~ 3.095。
