Spawing behavior and early life history of Lutjanus kasmira (Forsskål) is described from aquarium observations in 1976.The pesent paper deals with the first record of spawn-ing behavior and early life history among the family Lutjanidae.Spawning of L.kasmira took place between plueral males and females in the early hours of the night in mid-August when water temperatures ranged from 22.3°C to 25.0°C.Fertilized eggs are buoyant, spherical, and colorless, measuring 0.78mm-0.85mm in diameter, and containing a single oil globule.Hatching takes place 18 hours after fertilization.Newly hatched larvae measure about 1.83 mm in total length and have a large ellipsoid yolk.An oil globule is situated at the front tip of the yolk.Early larval stages of L.kasmira are described for the first 3 days after hatching.
