Population structure, growth, length-weight relationship and reproduction characteristics of leaping grey mullet (Liza saliens (Risso, 1810) were investigated in Beymelek Lagoon from February 2006 to January 2007. During the study, a total of 1248 leaping grey mullet were captured by gill- and trammel nets of various mesh sizes. Male to female ratio for leaping grey mullet population in Beymelek Lagoon was 1:2.71. The ages ranged from 1 to 4 years for males and from 0 to 5 years for females. The growth parameters of the von Bertalanffy equation were: L ∞ = 35.2 cm, K = 0.276 year-1 and t0 =-2.893 year for males, L ∞ = 35.9 cm, K = 0.386 year-1 and t0 =-1.760 year for females and L ∞ = 39.9 cm, K = 0.271 year-1 and t0 =-2.233 year for all individuals. The calculated length-weight equations were W
