“…The growth rate in weight was much slower during the first year of life increasing to reach its maximum at the end of the second year of life, then decreasing with further increasing in age. The same finding was recorded in the previous studies (Mehanna, 2006;Ahmed, 2011;Shalloof et al, 2019).…”

“…Mehanna (2006) concluded that "b" value (2.9448) is isometric growth for D. punctatus in Bardawil Lagoon. Shalloof et al (2019) concluded that "b" value (3.0067) is isometric growth for D. punctatus in Bardawil Lagoon, North Sinai, Egypt. These results were found to be close to the data obtained in the present work.…”

“…There are a few of published works on lengthweight relationship of the spotted sea bass Dicentrarchus punctatus (Rafail, 1971;Goncalves et al, 1997;El-Mor, 2002;Erguden and Turan, 2005;Mehanna 2006;Shalloof et al, 2019). A number of factors are known to influence the length weight relationship in fishes including growth phase, sex, size range, temperature and preservation techniques (Clark (1928).…”

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: L t = 37.48 (1-exp -0.58) t + 0.23) ); For growth in weight: W t = 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 1 st , 2 nd , 3 rd and 4 th year of life respectively.

“…Using the equation of Albertine-Berhaut (1973), gonadosomatic index (GSI) was calculated as follows: GSI = (gonad weight / body weight) X 100. At first maturity, for the estimation of the fish length, total body length was plotted against the frequency percentage of mature individuals, and then the length at 50% was considered as the length at first maturity (Sendecor, 1956). The number of mature eggs in the ovaries during the spawning season is defined as the absolute fecundity (Fabs.).…”

“…However, research on this species within the East Atlantic remains sparse [24]. In contrast, the European seabass has been more extensively studied, with research covering growth both in the Mediterranean [25,26] and Wales [27], dietary habits in the Mediterranean [28] and France [29], as well as growth and feeding in Portugal [30] and reproductive studies within the Mediterranean [31].…”

Various commercial fish species utilize different coastal habitats as nurseries in their juvenile stages, with surf zones being particularly crucial due to the protection and abundant food resources they offer. Among the species that rely on these areas are the spotted seabass (Dicentrarchus punctatus) and the European seabass (Dicentrarchus labrax). This study aimed to investigate the age and feeding habits of surf zone specimens of these species and explore their environmental adaptations. The average size for D. punctatus was 16.94 ± 4.05 cm, and for D. labrax, it was 23.23 ± 6.30 cm. The length–weight relationship for D. punctatus was TW = 0.013*TL2.885 (parameter a: 95% CI: 0.012–0.014; parameter b: 95% CI: 2.854–2.917), and for D. labrax, it was TW = 0.008*TL3.095 (parameter a: 95% CI: 0.006–0.009; parameter b: 95% CI: 3.040–3.151). In both D. punctatus (79.20%) and D. labrax (75.92%), the predominant age classes were 1+ and 2+. Significant variations in age class abundance were observed in D. punctatus based on the time of day, lunar phase, and season, while D. labrax showed variations only by season. A diet analysis revealed that both species primarily consume mysids and fish, with D. punctatus showing dietary variations related to the time of day, lunar phase, and season, and D. labrax showing variations with the time of day and season.
