Abstract
In the present study, 120 fish specimens (64 male and 56 female) of the five-lined snapper, Lutjanus quinquelineatus of variable sizes were used for demonstration the morphometric and meristic characteristics of this species in the Egyptian Red Sea, Hurghada fishing area. The total length varied from 15.3 to 28.7 cm in males and from 16.0 to 31.7 cm in females while their weights ranged between 44 and 378 g in males and between 48 and 512 g in females. This fish species showed constant meristic characters. Statistical interpretation of morphometric data indicated that there is direct relationship between total body length with head length (HL), snout length (SnL), eye diameter (ED) and length of caudal peduncle (CPL). The meristic characters like dorsal fin rays, anal fin rays, lateral line scales, gill rakers on lower arm and scales in transversal line were counted. The results revealed that there is no sexual dimorphism in L. quinquelineatus from Hurghada fishing area.
