The goal of this paper was to describe morphometric and meristic characteristics and weight – lenght relations of S. porcus population in the Bay of Medulin, and determine their correlation with age, gender ratio, condition factor, gonadosomatic and hepatosomatic index. Also, a comparison of aforementioned factors has been made with those presented of other researched populations. Samples were collected from March 2020 to February 2021 bimonthly, except in January when sampling was conducted once. Catch in two “poponica” nets with inner mesh size of 32 and 40 mm used in sampling was presented in total and monthly . A total of 163 S. porcus were collected. Each fish was weighed and analised for morphometric and meristic properties. Age, weight – lenght relations, von Bertalanffy growth function for lenght and weight growth, Fulton`s condition factor, gonadosomatic and hepatosomatic indexe were calculated. The catch was higher during the summer season. The dominance of female over males was determined with the ratio of 1:17.1 (χ2=128.99, p<0.05). The age of the individuals varied from two to ten years. The average age of females (6.06 ± 1.55 years) and males (4.44 ± 1.01 years) was determined. The average weight of all individuals was158.35 ± 76.16 g (161.95 ± 73.57 g for females, and 86.36 ± 23.45 g for males), and the total length was 20.05 ± 3.09 cm (20.31 ± 2.97 cm for females, and 15.67 ± 1.64 cm for males). Analysis of morphometric measures performed by t - test have shown that females have higher values of ratios of standard and total length (SL / TL, t = 4.46), preanal length and standard length (PA / SL, t = 2.31), preocular length and head length / CL, t = 3.81), while males have higher values of the ratio of anal fin length and standard length (LA / SL, t = 4.28), pectoral fin length and standard length (LP / SL, t = 3.71) and ventral fin length and standard length (LV / SL, t = 2.73). The fin formula of S. porcus in the Bay of Medulin is D: 12 + 10, P: 16, V: 1 + 5, A: 3 + 6, C: 15 - 16. Length-weight relationship showed that specimens progress equally in length and weight (b ~ 3). Analysis of age by von Bertalanffy's function of growth has shown that S. porcus in the Bay of Medulin grows slowly, but nevertheless due to the high average age they reach a large maximum size. Fulton condition factor was highest in June and showed no fluctuations towards the end of the year. The gonadosomatic index was highest from May to August (spawning season) with the exception in July. The hepatosomatic index was highest in June, decreased during the spawning season and grew again in winter. No statistically significant differences were found between coefficient b and Fulton condition factor by comparing infested specimens with healthy ones.
