| Abstract | ||
| In this study, a total of 1339 specimens of Sparus aurata were collected over a nine-month period, from May 2022 to January 2023, from Bardawil lagoon. The present study was conducted to identify and describe the morphological characteristics of S. aurata based on the external morphological features such as body shape, color, mouth position and fin arrangement. Also, to study growth pattern of this species collected from. The obtained morphological observations confirmed that the examined specimens were belonging to S. aurata. Its total length ranged from 11.4 to 29.9 cm, while its total weight ranged from 19 to 366 g. The length-weight relationship equation was W=0.0111 L3.0673 (R2 = 0.9705). Its age was determined using otolith radius reading technique and the age composition of this species was found to be 5 years. The von Bertalanffy growth parameters were: K=0.32y-1, L∞= 30.81 cm, t0= -1.38y , and W∞ = 408.86g. The estimated growth performance index (φ) was 2.48. | ||
