<br/><br/> A total of 397 fish specimens of the Spotted Sea Bass Dicentrarchus punctatus (Bloch, 1792) were random<br/>sampled monthly during the period from September 2019 to August 2020. They were obtained from fish landing site at<br/>Bitter Lakes, which is located along the Suez Canal for studying Length-weight relationships and condition factors.<br/>Also, in 2020 455 fish specimens of the Spotted Sea Bass from different fishing sites for studying age and growth. The<br/>calculated slope "b" value for length weight relationship reveled isometric growth (b= 3.1331). The maximum life span<br/>was four years for length range of 13.1-36.1 cm TL. The parameters of the von Bertalanffy growth function were: For<br/>growth in length: Lt = 37.48 (1-exp– 0.58) t + 0.23)); For growth in weight: Wt = 478.30 (1-exp– 0.58) t – 0.23)). Mean lengths at<br/>age were back-calculated for D. punctatus as 20.12; 27.36; 31.68 and 34.05 cm at the 1st, 2nd, 3rd and 4th year of life<br/>respectively.<br/>Keywords: Family Moronidae, Dicentrarchus punctatus, Age and growth, Bitter Lakes, Suez Canal
