| Abstract | ||||
| Family Sparidae is considered as one of the most commercial families of the small scale fishery of Suez bay. A Total of 800 specimens of Rhabdosaragus haffara were collected from the Suez bay landing site, El-salakhana, during the fishing season 2018-2019. The length-weight relationship equation is W=0.014L3.02 indicating an isometric growth. Age was determined by reading otoliths and revealed that the population has five age groups. The Von Bertlanffy equation was as follow; Lt = 27 (1-e-0.43(t+0.27)). Length at first capture LC= 13.0cm. The growth performance index (Φ) was estimated as 2.49. Total mortality was estimated to be Z=1.7, natural mortality is M=0.65, fishing mortality F= 1.05, and Exploitation rate is E= 0.62.The target and limit biological reference points are: FOpt=0.32 year−1 and FLimit = 0.43 year−1. Exploitation rate, FOpt, and FLimit indicated that the stock of R. haffara in Suez bay is overexploited and threatened. | ||||
