Length–weight relationships for five endemic fish species in the upper Yangtze River basin,China

Length – weight relationships were estimated for five endemic fish species in the upper Yangtze River: Platysmacheilus nudiventris Luo, Le & Chen, 1977, Xenophysogobio nudicorpa (Huang & Zhang, 1986), Homatula potanini (Günther, 1896), Leptobotia rubrilabris (Dabry de Thiersant, 1872), and Euchiloglanis kishinouyei Kimura, 1934. The a values ranged from 0.0079 to 0.0134, and b values from 2.833 to 3.081. These five endemic species are rare, small and difficult to find and capture. Thus the sampling period was lengthy, from May 2010 to May 2014. A total of 718 specimens were available for analysis, and the length – weight relationships are the first reports for these five endemic fish species.     

Length–weight relationship of six freshwater fish species in upper‐middle Tocantins River basin (Brazil)

Length–weight relationships (LWRs) were analyzed for six abundant fish species in the upper‐middle Tocantins River, northeastern Brazil. Analyses included data from 486 specimens sampled in five expeditions between August 2013 and May 2015 by gillnets. New maximum values of total lengths for the literature and FishBase were presented for six species, as well as first time estimates of LWR for Galeocharax gulo, Curimata acutirostris and Aphanotorulus emarginatus.     

Length–weight relationships of two schizothoracinae fish species from the Maquan River,the upper reaches of the Yarlung Zangbo River,Tibet, China

Length‐weight relationships (LWRs) were determined for two endemic fish species from the Maquan River, the upper of the Yarlung Zangbo River: (Ptychobarbus dipogon Regan, 1905, Schizothorax waltoni Regan, 1905). All the specimens were collected between May and September of 2014. Length–weight relationships for these two fish species were determined for the first time, and new maximum body weights were recorded for these two species. These results will be useful for fishery research, management and conservation of the Yarlung Zangbo River.     

Length–weight and length–length relationships of 20 fish species from the upper Yangtze River,southwest China

Length–weight (LWR) and length–length (LLR) relationships were estimated for 20 species of fish from the upper Yangtze River, southwest China.
