Length‐weight relationships of four fish species from the estuary of the Pearl River, South China

Summary Length‐weight relationships were determined for four fish species [Pterois russelii Bennett, 1831, Trichiurus margarites Li, 1992, Muraenesox cinereus (Forsskål, 1775), and Pterygotrigla ryukyuensis Matsubara & Hiyama, 1932]. Samples were collected from the estuary of the Pearl River with commercial trawls (mesh size 2 cm) periodically each season from May 2012 to January 2014. Prior to this study, the length‐weight relationships for these four species were unknown.
