Age and growth of gilt-head sea bream (Sparus aurata L.) in the Mirna Estuary, Northern Adriatic

The age and growth of the gilt-head sea bream, Sparus aurata L., were determined from speciments collected in the Mirna estuary (northern Adriatic) durin December (1990, 1991, 1992, 1993). Mean length at age data, as derived using scale readings, were used to estimate the growth parameters of the von Bertalanffy equation: L infinity=59.8 cm, K=0.15, to= -1.71 ; W infinity=5554 g, K=0.09 and to= -2.64. Length- weight relationship was estimated at : W=0.0112 L^3.052. Natural mortality was found to be M=0.32 per year (formula of D. Pauly, 1980) and M=0.41 per year (formula of V. A. Rikhter and V.N. Efanov, 1976).
