Length-weight relationship of thirteen demersal fishes from the tropical Brazilian continental shelf Eduardo, L. N. Fredou, T. Lira, A. S. Silva, L. V. S. Ferreira, B. P. /Bertrand, Arnaud /Ménard, Frédéric Lucena-Fredou, F. 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: 25 mm) at 35 stations between 15 and 60 m of depth. We provide novel LWRs for four species and expand the size range of 9 relationships previously established. 2019 text https://www.documentation.ird.fr/hor/fdi:010075525 fdi:010075525 Eduardo L.
