• [Display omitted] •Adjustments of ormer homeostasis to temperature change were marked on a multi-scale.•Antiox defenses varied significantly according to seasons, but not between genders.•Significant decrease of crude fat and protein during summer.•Fatty acid composition varied significantly between seasons (except for C22:5n3)•Significantly higher content of Ba, Co, Ni, Mn, Pb, Sb, and Se in winter and As in summer. Seasonal responses of green ormer in terms of antioxidant capacity and lipid peroxidation, proximate and fatty acid tissue composition, trace and macro elements concentrations over the seasons were studied in relation to temperature shifts in the Northern Adriatic Sea. Overall antioxidative defenses (SOD, TBARS, TAS, LDH) varied significantly (p < 0.001) according to seasons (primarily spring and summer). The proportions of overall SFA were highest in summer. The proportions of MUFA increased in autumn, with significant differences between genders in spring and summer, and spring, summer and autumn for C18:1n7 and C20:4n6. The only fatty acid lacking significant variation between seasons was C22:5n3. Significant overall differences were observed in summer vs. winter samples for As, Ba, Co, Ni, Mn, Pb, Sb, and Se content in soft tissues, however, gender variations were not significant. The data obtained in the study are of utmost importance for the management of this under-investigated species.
