%X This study propose to evaluate the fatty acid composition of the earthworm Eisenia andrei as an alternative lipid source for fish feed. Methods: The analytical composition of moisture, protein, lipids, ash and non-nitrogenous extract of earthworm meal Eisenia andrei and fishmeal was initially determined. Subsequently, the fatty acid contents of the lipids of these two ingredients were determined by gas chromatography. Results: Significant differences were found in the content of group ¦Ø-6 Polyunsaturated Fatty Acids (PUFA), with higher value (19.85 %) in the earthworm flour vs. 13,29% in fish meal, specifically the group of C14 PUFA, C16:2 n-4; C18: 2 n-6; C18: 3 n-6; C20:2 n-6; C20:3 n-6 and n-6 C20:4. The content of ¦Ø-3 fatty acids, mainly C20:5 n-3 and n-3 C22:6 is also important in the earthworn flour. Conclusions: the flour of E. Andrei could be recommended as a source of protein and lipid in fish feed because of its high protein and PUFA content
