“…The b value of 2.875 for Ptychobarbus kaznakovi was lower than the value of 2.918 previously reported for the Jinsha River (Lin et al, 2015) and 2.970 for the Zengqu River (Zhu et al, 2015). The b value of 3.090 for S. anteroventris in the present study exhibited a difference from previous values of 2.974 reported by Zhu et al (2017) and 2.540 reported by Pan et al (2018). For Cobitidae fishes (Table 2), the value of 2.847 for the b parameter of T. stolickai population was different from the value of 2.79 reported for the Ili River (Sui et al, 2015) and the value of 3.10 reported by Zhang et al (2016).…”

Length–weight relationships of five fish species from the Angqu River, China

et al. 2022

Length-weight relationships are presented for five fish species collected in the Angqu River, the headwater of the Lancang River in China. The following species were examined: Schizothorax lantsangensis, Ptychobarbus kaznakovi, Schizopygopsis anteroventris, Triplophysa stolickai and Triplophysa stenura. Specimens were collected at five sampling sites along the Angqu River over a two-year period between April 2017 and December 2019, using different fishing gear. The values of parameter a varied between 0.005 and 0.011 while those of parameter b ranged from 2.847 to 3.09. The coefficients of determination (r 2 ) were higher than .95. Based on the records in FishBase, the results of the present study represent the first report of LWRs for these five species in the Angqu River, with new total lengths also reported for two species (T. stolickai and T. stenura). Due to the unique location of the Angqu River, the data from the present study are expected to be valuable not only for monitoring these fish species, but also for developing and assessing appropriate management measures.

“…Te allometric coefcient b exhibited variation across the species, ranging from a minimum of 3.073 for L. annandalei to a maximum of 3.335 for L. berdmorei. Te coefcient (b) values have proven to be a crucial parameter in the analysis of length-weight relationships (LWRs), serving as a signifcant indicator for predicting the overall growth status of species [32][33][34][35]. Te spectrum of b values was within the typical limit of our existing experiments and supports fndings similar to those of Pan et al [33] and Hossain [35].…”

Four loaches, namely, Lepidocephalichthys guntea (Hamilton, 1822), Lepidocephalichthys annandalei (Chaudhuri, 1912), Lepidocephalichthys thermalis (Valenciennes, 1846), and Lepidocephalichthys berdmorei (Blyth, 1860) from the Cobitidae family, were collected from the Surma River, Bangladesh. Of the total 376 speciminia, 193 males (51.32%) and 183 females (48.67%) in number; were collected with the support of local fishermen using a variety of nets at 15-day intervals from November 2022 to April 2023. The length-weight relationship (LWR) parameters were analyzed using the equation W = a L b . L. annandalei displayed a notable isometric growth pattern, with a condition factor (K) ranging from 0.725 to 0.734. In addition, L. thermalis exhibited isometric growth among males, while females showcased positive allometric growth with a condition factor (K) varying between 0.697 and 0.714. L. guntea exhibited a consistent positive allometric growth pattern across all aspects, with a condition factor (K) ranging from 0.729 to 0.738. In contrast, L. berdmorei demonstrated positive allometric growth, but males and females both exhibited a negative allometric growth pattern. The condition factor (K) for L. berdmorei ranged from 0.699 to 0.702. This suggests a complex growth pattern influenced by both length and weight in every experimental loach. The research underscores the importance of recognizing gender-specific variations in growth patterns within species.

“…For a comparison of b values calculated in our study with 95% confidence limits of Bayesian estimation reported in FishBase (Froese & Pauly, ), the fish species were divided into two groups: (a) two species with b values within the Bayesian's confidence intervals ( S. lantsangensis and S. yunnanensis ); (b) a fish species of P. yunnanensis , estimated b value (2.68) was low in contrast to high b value (2.83–3.21) as per Bayesian approach (Froese & Pauly, ). LWR parameters may be influenced by a variety of factors such as diet, habitat, health, maturity status, preservation techniques, season and sex (Pan et al, ; Zhang et al, ; Zhu, Wang, Huang, & Yang, ); however, these factors were not considered in the present study.…”

“…The ichthyofauna of southwestern China is extremely diverse (Kang et al, ). However, there are few LWR studies on the fish in the region (He, Xiong, Sui, Jia, & Chen, ; Pan et al, ). In this study, the length‐weight relationships (LWR) for Platytropius yunnanensis He, Huang & Li, 1995, Schizothorax lantsangensis Tsao, 1964 and Schizothorax yunnanensis Norman, 1923 were determined.…”

Length-weight relationships of three fish species from southwestern China

Length‐weight relationships were determined for three fish species (Platytropius yunnanensis He, Huang & Li, 1995, Schizothorax lantsangensis Tsao, 1964 and Schizothorax yunnanensis Norman, 1923) from southwestern China. Specimens were collected using gillnets (20 × 2 m, mesh‐size 5 mm; soaking depth: 50–150 cm; exposure time: 10 hr/day) and electroshock fishing techniques quarterly from May 2016 to June 2017. Standard length (SL, nearest 0.1 cm) were determined as well as weight (nearest 0.1 g). The a values ranged from 0.01385 (S. lantsangensis) to 0.04155 (P. yunnanensis), the b values ranged from 2.68 (P. yunnanensis) to 2.98 (S. lantsangensis) and the coefficient of variation (r2) ranged from 0.957 (P. yunnanensis) to 0.963 (S. yunnanensis).
