Abstract

Age, growth, and mortality of the Gilthead Seabream, Sparus aurata were studied from a small-scaled fishery of Bardawil lagoon, (North Sinai, Egypt).499 specimens of Sparus aurata varied from 9.7 to 29 cm with weights ranging between 16.6 and 325.3 g. were collected from October to April during fishing season 2020-2021. The relationship between length and weight was W= 0.0239 L2.8357 (R2 = 0.9677) Age was determined by otoliths and age groups 0 to 5 years were observed. Growths in length and weight at the end of each year were calculated. The growth parameters of von Bertalanffy equation were calculated as (L∞ = 39.38, K = 0.1615 year-1, t0 = -2.31 year-1 and W∞= 798.5). Results affiremed that, growth performance index was 2.40 for length and 1.14 for weight. Mortality rates were 0.794 year-1; 0.23 year-1 and 0.56 year-1 for total, natural and fishing mortality, respectively. The currently exploitation rate (E) = 0.71.
