Length-weight relationships for 11 species at three small hydropower plants on the Sapucai-Mirim River (Grande River basin, Brazil)

摘要

This paper presents length-weight relationships (LWR) for 11 freshwater fish species from the Sapucai-Mirim River, a tributary of the Grande River basin, SAo Paulo, Brazil. The specimens were captured in quarterly samplings between March 2011 and December 2014, using gillnets of mesh size: 1.5-9.0cm between knots. The present study adds new information for the maximum length of seven species, and presents new LWR records for four species.
