Sardine, Sardina pilchardus (Walbaum, 1792) belongs to a small pelagic fish, it is a migratory species and it is also the most represented species in fisheries catches in the Republic of Croatia, as well as food for numerous fish and other marine organisms and as such is a very important factor food chain in the marine ecosystem. In this paper morphometric characteristics of sardines during the end of spawning and during the inactive phase of sexual cycle from different fisheries catch areas, zones (subzones) B (b2 and b3), E (e5 and e7) and F (f2) of the Adriatic Sea are shown. A total of 800 sardine individuals were analyzed in the period from March 9 to September 30, 2021. Length distribution, length-weight relationship, height-width ratio and fish condition coefficient were monitored. Analysis of the length-weight relationship indicated a total positive allometric growth (𝑏 =3.4333) with a strong correlation between total length and weight (R² = 0.9468, p<0.001). Positive allometry was also obtained in the regression analysis of the relationship between jaw length and weight (𝑏 =3.2276) (R² = 0.8808, p<0.001). The average Fulton’s coefficient of condition of the analyzed sardines was K = 0.70 ± 0.03 (K ± SD). The ANOVA test showed that the condition coefficients are significantly different, and the testing of individual differences with the Post Hoc analysis (Unequal N HSD) showed that almost all samples differ significantly from each other.
