Length-weight and length-length relationships of four endemic fish species from the upper Yellow River in the Tibetan Plateau, China

Abstract

Length–weight (LWRs) and length–length relationships (LLRs) were estimated for four important endemic fish species representating two genera and one family from the upper Yellow River in the Tibetan Plateau, China. Three of the species are endemic to the Tibetan Plateau, and the fourth is endemic to the Yellow River. The b values of all species were within expected ranges, varying between 2.54 and 3.33. The LLRs were highly correlated. The data of the four species represent the first description of their length–weight and length–length relationships.
