N2  - A total of 397 fish specimens of the Spotted Sea Bass Dicentrarchus punctatus (Bloch, 1792) were random
sampled monthly during the period from September 2019 to August 2020. They were obtained from fish landing site at
Bitter Lakes, which is located along the Suez Canal for studying Length-weight relationships and condition factors.
Also, in 2020 455 fish specimens of the Spotted Sea Bass from different fishing sites for studying age and growth. The
calculated slope "b" value for length weight relationship reveled isometric growth (b= 3.1331). The maximum life span
was four years for length range of 13.1-36.1 cm TL. The parameters of the von Bertalanffy growth function were: For
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
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
respectively.
