Abstract
Length-weight relationships (LWRs) are useful for calculating weight based on measurements of length. Here we provide LWRs for 17 species of fish from the rivers Vltava and Elbe in the Czech Republic, Central Europe. The samples were collected by electrofishing from May 2016 to August 2019. There are far fewer LWRs for riverine than lotic fish. All LWRs were significant with r2 values ranging from 0.99 for the European barbel (Barbus barbus) to 0.95 for European bullhead (Cottus gobio) and with estimated b values ranging from 2.93 in common dace (Leuciscus leuciscus) to 3.26 in non-native round goby (Neogobius melanostomus). These results increase the data on LWRs for fish in riverine environments and provides a good tool for managing fisheries and future studies.
