Length-weight relationship and diet of the catfish Cambeva guareiensis (Siluriformes; Trichomycteridae) [PDF]

Biota Neotropica, 2021
Abstract: The length-weight relationship (LWR) and diet of a small trichomycterid catfish, Cambeva guareiensis, was studied based on 58 specimens captured in Corrente stream, Guareí River basin, São Paulo, Brazil. LWR analyses showed values of a ranged from 0.0097 to 0.0149 and b from 2.858 to 3.250. The analysis of the diet showed that high amounts of
