“…Similar results were also found in many species in other areas, e.g. Cynoglossus arel of the northern Persian Gulf (Aghajanpour et al, 2015), Schizopygopsis thermalis and Schizothorax nukiangensis in the upper Nujiang-Salween River of China (He et al,2015), and Carassius carassius in the Nakdong River of South Korea (Lee et al,2015), etc. These studies show that even fish species with similar body shapes will also show significantly different a and b values in their LWRs.…”

Summary Length–weight relationships (LWRs) were estimated for eight native fish species collected in the lower reaches of the Pearl River, Guangdong Province, South China. Fish were sampled in March and September 2014 and January 2015, using gillnets with various mesh sizes (5–8 cm) and trawl nets with a 3 cm mesh size. A total of 568 specimens of the eight species were analyzed. The r2 values for these species ranged from 0.951 to 0.991. The b values ranged from 3.00 for Takifugu ocellatus and Moolgarda cunnesius, to 3.57 for Clupanodon thrissa. New maximum total lengths are recorded for Takifugu ocellatus (17.6 cm) and Liza carinata (24.4 cm). For five species (Clupanodon thrissa, Megalobrama terminalis, Collichthys lucidus, Coilia grayii, Takifugu ocellatus), the LWRs are presented to fishbase for the first time.

“…Seven species had no previous LWR records in FishBase (Froese & Pauly, ). Of the seven species three have been recorded in published papers (Baek et al., ; Kim et al., ; Lee et al., ; Park et al., ; Yoon et al., ). All of data fell within the expected length‐weight range (2.5–3.5) found in FishBase.…”

“…Thus, in this study, 10 species data were used to estimate LWR of fish at the catchment area of Busan metropolitan City in South Korea. Both FishBase and published papers were also comprehensively reviewed to find undefined LWR data (Baek et al., ; Froese & Pauly, ; Kim, Yoon, Won, Byeon, & Jang, ; Lee et al., ; Park et al., ; Yoon, Kim, Baek, Byeon, & Jang, ).…”

This study was undertaken to estimate the life history parameters of the shining catfish (Tachysurus nitidus) and small-scale yellowfin (Plagiognathops microlepis) in Lake Dianshan using length-frequency data of 4070 specimens. Both species exhibited isometric growth. The von Bertalanffy growth constants for Tachysurus nitidus were L∞=25.15 cm, K=0.19 yr −1 , and t0=-0.378 yr with a derived growth performance index of Ø′ =2.08. The corresponding estimates for Plagiognathops microlepis were L∞=36.5 cm, K=0.10 yr −1 , t0=-0.40 yr and Ø′=2.125. The total mortality rate, Z, for Pelteobagrus nitidus was estimated as 1.51 yr −1 , with the fishing mortality, F, being calculated as 1.13 yr −1. The mortality estimates for Plagiognathops microlepis were Z=0.54 yr −1 and F=0.33 yr −1. The exploitation rates of both species (E=0.75 and E=0.61 for Tachysurus nitidusand Plagiognathops microlepis respectively) were higher than the optimum exploitation criterion (Eopt=0.5), which is indicative of over-fishing. The size-structured yield per recruit (YPR) analysis confirmed that both stocks are highly exploited, since current fishing mortality rates were higher than the biological reference points (BRPs) F0.1 (0.16 for Tachysurus nitidus and 0.15 for Plagiognathops microlepis) and Fmax (0.2 and 0.225 for Tachysurus nitidusand Plagiognathops microlepis respectively). The results further suggest that, for a sustainable management and an increase in yield, the current fishing effort for Tachysurus nitidus, be reduced to 0.2 and for Plagiognathops microlepis be decreased to 0.225. Other management action, such as gradual increase of fishing gears mesh sizes could also be considered necessary for sustainable exploitation of these stocks.
