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.

捷克共和国河流中17种常见欧洲鱼类长重关系的回归分析

长度-重量关系（LWR）可用于根据长度测量值计算重量。在这里，我们提供了来自中欧捷克共和国伏尔塔瓦河和易北河的17种鱼类的LWR。样品于2016年5月至2019年8月通过电铸采集。河流鱼类的LWR远少于乳液鱼类。所有LWR都是显著的，r2值从欧洲杠铃（Barbus Barbus）的0.99到欧洲牛头鱼（Cottus gobio）的0.95，估计的b值从普通dace（Leciscus Leuciscus）的2.93到非本地圆虾虎鱼（Neogobius melanostomus）的3.26。这些结果增加了河流环境中鱼类的LWR数据，并为管理渔业和未来的研究提供了一个很好的工具。

期刊介绍： The European Journal of Environmental Sciences offers a mixture of original refereed research papers, which bring you some of the most exciting developments in environmental sciences in the broadest sense, often with an inter- or trans-disciplinary perspective, focused on the European problems. The journal also includes critical reviews on topical issues, and overviews of the status of environmental protection in particular regions / countries. The journal covers a broad range of topics, including direct or indirect interactions between abiotic or biotic components of the environment, interactions of environment with human society, etc. The journal is published twice a year (June, December).
