Fish Ecology and Management Studies

We established the length–weight relationships (LWR) for 78 fish species from the São Francisco River basin, Brazil. Samples were originated from different scientific projects performed between 1993 and 2019. Fishing gears used were mainly gillnets and cast nets of various mesh sizes. Specimens varied from 0.6 to 128 cm (18.1 ± 11.8 cm) and from 0.01 to 26,900 g (317.9 ± 733.6 g). The allometric coefficient b varied from 2.509 to 3.494. For 66 species, the LWR parameters were completely novel and, for the other 12 species, are present for the first time for the São Francisco River basin.
