ABSTRACT
In this study, the length and weight of eight fish species from Xinjiang, China, were measured, the length-weight relationships (LWRs) were analyzed, and growth status was evaluated. A total of 274 samples were collected by trawl nets (set gill nets) and ground bamboo cages with net diameters of 15-20 mm and 25-30 mm, respectively. In the present study, the LWRs were determined for eight species of plateau fish and the b-values for the eight species ranged from 2.672-3.320, which were all within the expected range of 2.5-3.5. The results of the study provided reference values for the b-values of Schizothorax irregularis, and we measured the maximum length of Schizothorax biddulphi. The statistical relationships between the length and weight of these eight fish species were highly significant (p < 0.01), with r2 values > 0.819.
