Impact of Diets Containing Plant Raw Materials as Fish Meal and Fish Oil Replacement on Rainbow Trout (Oncorhynchus mykiss), Gilthead Sea Bream (Sparus aurata), and Common Carp (Cyprinus carpio) Freshness

Table 7

Individual ATP breakdown product concentrations in mol g⁻¹ fish fillet in gilthead sea bream fed with the four experimental diets (D1–D4). Data are mean ± SD . Means not sharing a common superscript letter are significantly different . IMP: inosine monophosphate; Ino: inosine; Hx: hypoxanthine.
