Length-weight relationships of three endangered tidal pool fish species on Jeju Island, Korea

Abstract

Summary The length–weight relationships (LWRs) of three endangered tidal pool fishes, Spratelloides gracilis (Temminck & Schlegel, 1846), Atherion elymus Jordan & Starks, 1901, and Enneapterygius etheostomus (Jordan & Snyder, 1902), from Jeju Island, Korea, were analysed. A total of 280 specimens were sampled using hand nets (mesh size 1 mm) or by dredge (mesh size 5 mm) from July 2015 to July 2016. This study provides the first LWRs for two species, a new LWR for one species, and a new maximum length data for two species.

Length-weight relationships of three fish species from Beibu Gulf in China

“…Standard length (SL) of each individual was measured to the nearest 0.1 cm and body weight (BW) was weighed to the nearest 0.1 g. The LWRs (W = a L b ) was fitted with the linear regression model using log‐transformed data, where W is the BW (g) and L is SL (cm). The 95% confidence intervals (CIs) were calculated for parameters a and b (Froese, ; Kwun et al, ).…”

“…The length–weight relationships (LWRs) of fish species can provide baseline information for the fishery investigation, stock assessment and management (Froese, ; Kwun, Park, Kim, Bae, & Jeong, ). Moreover, LWRs can describe the growth pattern of fish species, and it is the basis for further study on the fluctuation and utilization of resource stock (Zhan, ).…”
