Length‐weight relationships (LWR) and length‐length relationships (LLR) were provided for eight species inhabiting Northeastern Brazilian coast. Nine transects (5, 15, 30 m deep) between Sergipe and Vaza‐Barris rivers mouths were sampled monthly from September 2013 to August 2014. Each sampling was carried out using a shrimp boat equipped with double ring nets (4 m mouth wide, 10 m long and 20 mm mesh size) and trawlings were performed for 15 min. Fishes were measured (standard and total length, 0.1 cm) and weighted (total weight, 0.01 g). We provide LWR and LLR coefficients for these eight species, including new maximum TL for five species, and discuss the similarity of these results with estimates available in Fishbase.
