Effect of seasonal temperature shifts on body homeostasis, biochemical parameters and chemical composition of green ormer (Haliotis tuberculata) in the Northern Adriatic

[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
