Abstract This study reports the Length‐Weight Relationships (LWR) for 10 freshwater fish species sampled in the Atlantic Rainforest, Southern Brazil. Sampling was conducted between 2016 and 2017, in nine streams, using electrofishing. Collected fishes were fixed in formalin, and thus some shrinking was unavoidable. The values of parameter b of the LWR ( W = aL b ) ranged between 2.5 and 3.5. We report for the first time the LWR for seven species: Geophagus iporanguensis , Isbrueckerichthys duseni , Hypostomus interruptus , Kronichthys lacerta , Chasmocranu lopezi , Astyanax lacustris e Neoplecostomus ribeirensis . We highlight the importance of the LWR data in supporting further studies on fish stocks and environment in the Atlantic Rainforest, thereby contributing to the database needed to develop fisheries management and maintenance of ecosystem services.
