Growth of juvenile striped seabream, Lithognathus mormyrus (Teleostei: Sparidae) in the Adriatic Sea

Growth of juvenile striped seabream, Lithognathus mormyrus from the Duće Glava, eastern Adriatic Sea, was analyzed. A total of 2133 juveniles, ranging in total length from 0.8 to 10.3 cm, were caught. Most individuals (99.53%) belonged to the 0+ cohort. The first settlers, aged 1.5-2.0 months, were recorded at the end of August. Relationship between total length and weight indicates positive allometric growth (b = 3.141). The condition factor, as a consequence of length-weight relationship, was CF = 1.245. The Gompertz equation (c = 0.080 mm day-1 ; R2 = 0.962) seems to be the most appropriate for the description of young L. mormyrus growth. The Gompertz and von Bertalanffy models, used for juvenile L. mormyrus, fit its data very well in first five months when the most intensive growth were recorded, while after that period, Gompertz model overestimated growth in comparison with the real growth slope and the von Bertalanffy model underestimated growth.
