Length–weight relationships of ten fish species from the Jingjiang reach of the Yangtze River, China

Abstract

The length-weight relationships (LWRs) were estimated for ten fish species from the Jingjiang reach of the Yangtze River, China. Samples were collected using a combination set-net consisting of a 40-meter net wall (mesh size: 1.8 cm) and two fyke nets (mesh size: 0.9 cm) on the 1st, 11th and 21st of each month from January 2012 to December 2017. The b values of all species were within the expected ranges, varying between 2.849 and 3.292. This study provides the LWR parameters for

Length‐length and length‐weight relationships of ten fish species in Yichang reach of middle Yangtze River below Gezhouba Dam, China

“…were consistent with the expected range of 2.5-3.5 (Froese, 2006;Guo et al, 2020). Some deviations of the parameter b for some species in this study were identified when compared with other studies (Chen et al, 2016;Huang et al, 2017;Shao et al, 2016;Wang et al, 2012).…”

“…The LWRs are influenced by a variety of factors, such as growth phase, gender, fishing, season, temperature, and food (Froese, 2006; Le Cren, 1951; Tesch, 1971). In this study, we estimated the LWRs based on the long‐term surveyed data following Liu et al, (2013), and the estimated parameters should be considered as the mean annual values (Guo et al, 2020). Our results provided the new data for FishBase (Froese & Pauly, 2022), as well as for understanding fish growth pattern and establishing conservation measures of fish resources after fishing closure in the Yangtze River.…”

Length‐weight relationships of 12 dominant fish species from a Ramsar Wetland in India: Vembanad Lake

“…LWRs also facilitate comparisons of life history and morphological parameters between different fish species and/or between fish populations of different ecological habitats (Gonçalves et al, 1997; Karna et al, 2018). LWRs have been widely used in combination with other parameters in recent years for the conservation and management of fisheries resources (Guo et al, 2019, 2020). However, the LWRs of important fish species inhabiting Vembanad Lake in India have been rarely estimated, excepting the previous studies of Roshni et al (2016) and Roshni and Renjithkumar (2020).…”
