Abstract
In the current work, the overall ratio between males and females of Sarpa salpa
was 1:0.32. The first sexual maturity of males was recorded at length group (21.1-
24cm) by 66.6% and the female was recorded at length group (24.1-27) by 50%.
Ovaries of S. salpa were examined. The smallest mature female had a total body
length of 29 cm and 387.73 gm weight with absolute fecundity of 2,978,440 eggs. The
largest female had total body length of 39 cm and body weight of 918.86 gm with
absolute fecundity 1,685,729 eggs. Based on the results of maturity stages, gonadosomatic
indices (G.S.I) and ova diameters, the study showed clearly that spawning
season of S. salpa in the Libyan coast of the Mediterranean waters extends from
October to December.
