摘要: The present study provides length-weight relationships (LWRs) for nine fish species from the Ulungur River basin, Northwest China (46 degrees 08 '-47 degrees 30 ' N, 87 degrees 00 '-90 degrees 30 ' E). The fishes were collected quarterly (Spring, Summer and Autumn) from 2019 to 2021 with multi mesh composite gill nets (mesh size: 8.6 x 8.6 cm, 3.9 x 3.9 cm, 1.3 x 1.3 cm, 2.0 x 2.0 cm, 11.0 x 11.0 cm, 1.6 x 1.6 cm, 2.5 x 2.5 cm, 4.8 x 4.8 cm, 3.1 x 3.1 cm, 1.0 x 1.0 cm, 7.0 x 7.0 cm, 5.8 x 5.8 cm; with 2.5 m long for each mesh, and a total length of 30 m.). The estimate of coefficient b for species ranged positively from 2.536 to 3.259, respectively. The coefficient of determination (r(2)) for each species with range of 0.911-0.986.
