Summary

Length–weight relationships of 23 fish species from the Guaratiba mangrove area in southeastern Brazil were estimated. The value of the parameter b ranged from 2.63 to 3.39 (median = 2.97). This study presents the first estimation of LWR for two species (Ctenogobius stomatus and Ctenogobius boleosoma). New maximum length records were obtained for two species (Poecilla vivipara and Ctenogobius stomatus).
