Abstract

The present study describes new estimates of length-weight relationships (LWRs) for 5 indigenous fish species collected from the South China Sea, Daya Bay (22°30′-22°50′ N, 114°29′ -114°49′ E). The fishes were collected quarterly (Spring, Summer, Autumn and Winter) from 2019 to 2021 with multi mesh composite gill nets (35.0 m long, 4.0 m high, and mesh size 15.0–116.0mm). Total length (to nearest 0.01 cm, L) and total weight (to nearest 0.01 g, W) were determined. The estimate of coefficient b for species ranged positively from 2.489 to 4.146, respectively. The coefficient of determination (r2 ) for each species with range of 0.93-0.97. Findings of this study have implications in the management and conservation of the species- specific fisheries resources within the geographical range.
