Abstract

Abstract The length-weight relationship parameter is important for obtaining fish weight and biomass data with relevant implications about species role on ecosystem functioning. Here we report the length-weight relationship (LWR) for 24 fish species from three streams located in the Atlantic Forest in the Rio de Janeiro State, Brazil. Fish were collected with electrofishing and standard length (cm) and wet weight (g) were measured to obtain the a and b parameters of the Log (W) = Log (a) + b Log (SL) equation. Length-weight relationships for seven out of 24 species (Hypostomus punctatus, Deuterodon taeniatus, Deuterodon hastatus, Deutorodon janeiroensis, Characidium vidali, Characidium interruptum and Rineloricaria zawadiskii) are reported for the first time. The length-weight relationships reported here contribute to the database that can support fish diversity conservation, fisheries management plans and studies on fish biology.

巴西里约热内卢大西洋森林中24种流栖鱼类的长度-重量关系

长度-重量关系参数对于获得鱼类体重和生物量数据具有重要意义，并对物种在生态系统功能中的作用具有重要意义。本文报道了巴西里约热内卢州大西洋森林三条河流中24种鱼类的长度-重量关系(LWR)。采用电钓法采集鱼体，测量标准长度(cm)和湿重(g)，得到Log (W) = Log (a) + b Log (SL)方程的a和b参数。24种中有7种为首次报道的长-重关系，分别为:斑点下齿(Hypostomus punctatus)、带齿后齿(Deuterodon taeniatus)、hastatus后齿(Deuterodon hastatus)、janeiroensis、vidali charidium、interruptum charidium和Rineloricaria zawadiskii。本文报告的长度-重量关系有助于建立数据库，为鱼类多样性保护、渔业管理计划和鱼类生物学研究提供支持。
