Length-weight and length-length relationships of four native fish species of the Qinghai-Tibet Plateau, China

Abstract

Summary This study presents the length–weight (LWR) and length–length relationships (LLR) of four fish species (Gymnocypris namensis Wu & Ren, 1982; Herzensteinia microcephalus Herzenstein, 1891; Triplophysa stenura Herzenstein, 1888; and Triplophysa brevicauda Herzenstein, 1888) collected from the Qinghai‐Tibet Plateau, China. A total of 291 specimens was collected using electric fishing (12V), gill nets (mesh size: 2 × 2 cm, 3 × 3 cm) and cast nets (mesh size: 2 × 2 cm), in July 1998 and October 2014.

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

“…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). For T. stenura species, a difference in the b value was also observed, compared with previous reports of Lin et al (2015, 2017), Fan et al (2015) and Liang et al (2016).…”

Length-weight and length-length relationships of four native fish species from the Yalong River, China

“…Prior to regression, outliers for each species were eliminated by using log TL ‐log BW plots (Froese, ). The relationship between total length (TL) and standard length (SL) was delineated by linear regression: TL = p + qSL (Liang et al., ).…”

Length‐weight and length‐length relationships of three fish species from the lower Yalong River, China

“…Parameters a and b were obtained from log-transformed equation log W = log a + blog TL, and the 95% confidence limits (CL) of a and b were estimated (Froese, 2006). The length-length relationship was described by linear function: TL = p + qSL, where SL is standard length (cm; Liang et al, 2015). The analysis was conducted using SPSS 16.0 and OriginPro 2016 at 0.001 significant level.…”
