Nutritional behavior and feed intake contribute to fish growth dynamics, productive indices, and meat quality. In this study, productive indices and meat quality were analyzed in three fish species with different nutritional spectrums: a predatory species, the rainbow trout (Oncorhynchus mykiss), an omnivorous species, the wild Danube carp (Cyprinus carpio), and a planktivorous-detritivorous species, the Golden grey mullet (Chelon auratus). A phenotypic characterization of the species was performed (measurements) and body size indices were calculated [Fulton condition factor (K), profile index (Pi), thickness index (Ti), Kiselev quality index (KQi), and fleshiness indices (Ci1-Ci2)], slaughter yields and organs weight ratio and body segments, as well as meat quality. The results show us higher protein values in fish meat from natural environments (Danube carp and Golden grey mullet) due to the more varied nutritional spectrum. Slaughter yields were also better for wild species.
