SummaryLength-weight relationships were determined for three fish species [Bregmaceros rarisquamosus Munro, 1950; Sardinella albella (Valenciennes, 1847)
| INTRODUCTIONThe South China Sea has high marine fish species richness and endemism (Xiong et al., 2017). However, the information of Chinese marine fish is very scarce. Length-weight relationship (LWR) is a widely used tool in fisheries science and management (Xiong et al., 2015). In this study, the LWR for Bregmaceros rarisquamosus Munro, 1950, Sardinella albella (Valenciennes, 1847, and Cynoglossus macrolepidotus (Bleeker, 1851) were first determined. W is the weight (g) and L is the length (cm), was fitted with a simple linear regression model using log-transformed data. The 95% confidence interval (CI) was determined for parameters a and b (Froese, 2006).
| MATERIALS AND METHODS
| RESULTSAll sample size, size range, length-weight parameters a and b, and the correlation coefficient (r 2 ) are listed in Table 1.
| DISCUSSIONThe estimated values for the parameter b remained for all three studied species within the expected range of 2.5-3.5 (Froese, 2006
