Length–weight relationships (LWR) were determined for seven commercially important species of catfishes (Siluriformes, Ariidae) from the Amazon Coastal Zone (ACZ), Brazil. The analyses included 3628 specimens sampled in three trawling expeditions: dry season of 1996 (111 hauls), rainy season of 1997 (120 hauls), and dry season of 1997 (120 hauls). Bottom-trawl nets were utilized for sampling. Length-weight estimates for Amphiarius phrygiatus, Amphiarius rugispinis, Aspistor quadriscutis, Notarius grandicassis, Sciades couma, Sciades parkeri and Sciades proops.
