Length-weight relationships were calculated for 30 fish species belonging to 14 families using 2562 specimens caught in coastal waters of the western Gulf of Mexico. The number of fish measured varied by species, ranging from 32 individuals for Polydactylus octonemus to 177 for Anchoa hepsetus. Most of the values of the parameter b are within expected range of 2.5-3.5. The effects of sex for some of these species were taken into account; however, none of them had significantly different. The results of this study provide useful basic biological information about the most conspicuous species of fish caught in the study area.
