Megjegyzések:	The rising cost of fishmeal and concerns about its sustainability have led to efforts in exploring alternative ingredients that could partially replace it. The Black Soldier Fly (BSF), Hermetian illucens larvae hold potential due to their high protein and fat contents. This study aimed to evaluate growth performance, amino acids and fatty acids composition of fillets and blood biochemistry of hybrid catfish (Heteroclarias) cultured on BSF larval-based diets. The experiment was conducted in a recirculating system, circular poly tanks (350 L) in a completely randomized design. Four isonitrogenous (400 gkg-1 crude protein) and isolipidic (140 gkg-1 crude fat) diets were formulated in which fishmeal was replaced at 0, 25, 50, and 75% with BSF larval meal and fish oil was completely replaced with corn oil in the test diets. Fish (initial body weight of 200?27g, 15 fish per tank, 4 treatments, 3 replicates,) were fed at 3% body weight for 8 weeks. All diets were accepted by fish. Fish fed BSF 50 had the highest final mean body weight, similar to the Control and BSF 25 groups. Fish fed BSF 75 had the lowest mean body weight, significantly different (p<0.05) from the other treatments. There were no significant differences (p>0.05) in the FCR among the dietary treatments. The amino acids and fatty acids composition of fillets of fish fed BSF larval diets compared favourably with fishmeal-based Control diet. Dietary inclusion of BSF larval meal and corn oil had no significant impact (p > 0.05) on deposition or retention of ARA, EPA, DHA and n-3 PUFA in fish fillets. Results of blood biochemical analysis indicate that the test diets are nutritionally adequate. The findings of this study suggest that BSF larval meal may partially replace dietary fishmeal up to 50% (200 gkg-1) and corn oil may completely replace fish oil without exerting negative impacts on growth, feed conversion, fillet quality, physiological stress, and health of hybrid African catfish Heteroclarias
