Abstract

Atlantic stargazer (Uranoscopus scaber Linnaeus, 1758) fish samples were monthly collected during 2001-2002 from landing of bottom trawlers operating off Alexandria, Egypt. The results revealed that this species did not exceed five years of age and females were larger than males, reaching 30.0 cm and 26.0 cm, respectively. The study of length-weight relationship showed that no significant difference between males and females (P>0.05). Growth performance in length (Ф/) and weight (Ф) were found to be 2.62 and 1.05, respectively. The von Bertalanffy growth parameters were found to be L∞ =35.02 cm, K=0.3424 yr-1 and to=- 1.011 yr. The rates of total mortality (Z), natural mortality (M) and fishing mortality (F) were 0.901 yr-1, 0.554 yr-1 and 0.347 yr-1, respectively. This population is characterized by low exploitation rate (E= 0.229).
