Length-weight and length-length relationships of four fish species from rivers in the Tibetan Plateau, China

Abstract

Length-weight (LWRs) and length–length relationships (LLRs) were estimated for three native and one non-endemic fish species, representating three families and four genera from four sites in the Tibetan Plateau, China. Specimens were caught by a gill net (mesh size: 1-inch), cast net (mesh size 1–2 cm; depth: 1–2 m) and a traditional shrimp coop during July 2006, and from July 2013 to August 2014. The LWRs b-values of all fish species ranged from 2.63 to 3.29. All correlation coefficient values were higher than 0.95. Their LLRs were highly correlated.
