Length–weight relationships of four marine fish species caught in the South China Sea

Summary Length–weight relationships are described for four marine teleost fish species caught in the South China Sea. A total of 625 individuals were collected from April to August 2007 and November 2012 using a bottom trawl (mesh size, 3.9 cm) and longline fishing. The values of parameters a and b ranged from 0.004612 to 0.02137 and 3.019 to 3.371, respectively. The high r2 values (all >.950) indicate that these relationships are robust and will be appropriate for use in fisheries management of these species.
