This study provides the length-weight relationship (LWR) for 13 demersal fish species belonging to 11 families and 8 orders. Data were collected in the northeast Brazilian continental shelf during two scientific surveys (2015 and 2017) using a bottom trawl net (side length of body mesh: 40 mm, side length of cod-end mesh: 25mm) at 35 stations between 15 and 60 m of depth. We provide novel LWRs for 4 species and expand the size range of 9 relationships previously established.
