This study aimed to standardize the anatomical nomenclature and labeling of commercial cuts of tambaqui (Colossoma macropomum) and pirarucu (Arapaima gigas) filleted in agro-industries in Rondônia state, Brazil. The applied and descriptive research involved mapping the cuts, analyzing their anatomy, yield, and lipid profiles in accordance with current regulations. The results revealed significant nutritional variations among the commercial cuts. For tambaqui (1.8–2.4 kg), the band cut showed the highest content of polyunsaturated fatty acids (PUFAs) (19.05 g 100g⁻¹), while the rib cut was the richest in omega-3 (n-3) fatty acids (12.87 g 100g⁻¹). For pirarucu (11–14 kg), mechanically separated meat (MSM) was the most nutrient-dense cut, with the highest levels of PUFAs (28.02 g 100g⁻¹), n-3 (12.92 g 100g⁻¹), and docosahexaenoic acid (DHA) (4.41 g 100g⁻¹). A standardization proposal was developed and validated using the Delphi technique with industry experts. In conclusion, the anatomical standardization of the cuts ensures commercial consistency, compliance with regulations, and improved consumer identification by highlighting the distinct culinary applications and nutritional values of each cut, thereby adding value to the Amazonian aquaculture chain.
