This study estimated the a and b parameters of the length–weight relationships of 15 fishes from the Mira and Caunapí rivers, San Andrés de Tumaco, Nariño, Colombia. The specimens were captured during four samplings periods between 2015 and 2016 using a different a combination of fishing gillnets and electrofishing. The a values ranged from 0.0002 to 0.04 and b values ranged from 2.86 to 3.6. The data presented here are tentative estimates because the fish have been weighted and measured after fixation in formalin and ethanol, however, these data are references for weight‐length relationship for 15 species, the maximum weight for the same 15, and new maximum lengths for 3 species.
