Sažetak
The age, growth and mortality parameters of Scorpaena scrofa from the eastern middle Adriatic Sea were studied. Total lengths (TL) of 350 specimens ranging from 13.5 to 58.2 cm were obtained by trammel net fishing (2000-2005). Total weight was ranging from 60.0 to 3650.0g. The mean lengths, as well as the age frequency distributions of males and females were not significantly different. Scales showed clearly the ring pattern. The opaque ring was deposited during the summer months. The length-weight relationship showed a positive allometric growth (b = 3.165 ; R2 = 0.989). The parameters of the von Bertalanffy growth equation were: L∞ = 68.20 cm ; K = 0.084 per year ; t0 = -1.378 year ; R2 = 0.981. This study revealed that S. scrofa is a relatively slow growing and long-lived species with a life span in excess of 25 years. The mortality parameters were: Z=0, 27, M=0, 22 and F=0, 05.
