Length composition data (Total length) of Spotted Sea bass Dicentrarchus punctatus), landed between January 2020 to December 2021 in Coastal Waters of Mediterranean coast North Sinai Egypt were monthly used to estimate the population parameters and length weight relationship of females, males and combined sexes (W = 0.0099 L 2.9839, W = 0.0108 L 2.9555, W = 0.0099 L 2.985). The average condition factor was 0.93 and the relative condition factor was 1.0. The relative condition factor (Kn) of kawakawa is 0.98 and low in small-sized fish (10-13 cm TL) then tends to stable in size fish 14-21 cm TL, whereas, and fluctuates in mature fish, it shows a declining trend with increasing length. The highest relative condition factor appears at the upper limit of the 20 cm long class at 1.2, and the lowest occurs at the upper limit of the 34 cm long class at 0.95. Generally, the monthly value shows from 0.94 to 1.23. The growth parameters of von Bertalanffy equation were estimated as L∞ = 37.36.2 cm, K = 0.2371 year -1 and t0: - 0.7505 year-1 and W∞ = 488.96. This study strongly recommended minimizing the fishing activity in this area. Or use fishing methods that preserve the fish stocks of this species and not catch small fish.
