We provide supplementary dataset supporting the paper "Length-weight relationships in 45 Neotropical fish species from the
upper Tocantins River basin (Brazil)", submitted to Journal of Applied Ichthyology
LW Serra da Mesa - 45 species.csv comprises Length and Weight values for 45 species of the Serra da Mesa reservoir, upper Tocantins river, GO, BR. Data based on measures of 58,140 individuals. Length is the distance from the snout to the end of caudal fin, measured with a scale (0.1 cm precision) and Weight is the wet weight measured with a digital balance (0.01 g precision).
