Abstract: In some countries, sea lamprey (Petromyzon marinus L.) is considered a delicacy and its intensively captured during spawning migration, being its fishery an important source of income for inland commercial fishermen in Western Europe (Portugal, Spain, France), providing hundreds of thousands of sea lamprey to restaurants every year. In Portugal, it is sold at high prices in restaurants where tens of thousands of sea lamprey are consumed annually. This work characterizes sea lamprey proximate composition of fillets, providing the fatty acid profile, crude total protein, total cholesterol, macro and micro minerals, gross energy contents and lipid healthy indexes. 30# sea lamprey were captured during early spawning migration in Guadiana and Mondego River basins, Portugal. The results revealed that fillets present a high lipid content (50,7g/100g, dry weight), a high gross energy (684,5Kcal/100 g, dry weight), a low total cholesterol (0.056g/100 g, dry weight) and a very high ω3/ω6 ratio (11,2). Thus, sea lamprey could be a healthy lipid choice for consumers.
