Length weight relationship of thirteen demersal reef fish species in three genera in two families Serranidae and Lutjanidae from northern Arabian Sea was estimated. A total of 7344 specimens from the thirteen species were used for the study. Sample sizes ranged from 25 to 4428 mm with the smallest sample size being that of Cephalopholis sonnerati. New maximum length was estimated for Epinephelus areolatus, Pristipomoides typus and Pinjalo lewisi. Significant differences in the slopes of length weight relationships between males and females for Epinephelus diacanthus, was observed. Fishes studied are in the Least Concern (LC) category in the IUCN list.
