Abstract

Length and weight relationships (LWR) were estimated for 39 fish species from 30 families from the northwestern Gulf of Mexico. Fish specimens were sampled during four oceanographic campaigns (February and October 2016, June and September 2017) using a shrimp trawl net and benthic sled net in 20 locations at depths that ranged from 43 to 3,608 m. New maximum standard length (SL) was obtained for Cyclothone alba, C. braueri, C. pseudopallida, and Lepophidium brevibarbe. A positive allometric growth was reported in 22 species and 17 showed a negative allometric growth.
