AB Macroalgae have been recently described as a potential ingredient for aquafeeds, exerting several physiological benefits. Grass carp(Ctenopharyngodon idella) is a freshwater species, which has been the major fish species produced in the world in the last years. Inorder to determine the potential use of macroalgal wracks in fish feeding, C. idella juveniles were fed with an extruded commercialdiet (CD) or the CD supplemented with 7% of a wind dried-powder (1 mm) from either a multispecific macroalgal wrack (CD+ MU7) or a monospecific macroalgal wrack (CD + MO7) obtained from Gran Canaria island (Spain) coasts. After 100 days offeeding, survival, fish weight, and body indexes were determined, and muscle, liver, and digestive tract samples were collected.The total antioxidant capacity of macroalgal wracks was analyzed by assesing the antioxidant defense response and digestiveenzymes activity in fish. Finally, muscle proximate composition, lipid classes (LC), and fatty acid (FA) profiles were alsostudied. Our results suggest that dietary inclusion of macroalgal wracks does not have negative effects on growth, proximate,and lipid composition, antioxidative status, or digestive capacity of C. idella. In fact, both macroalgal wracks caused a generallower fat deposition, and the multispecific wrack enhanced catalase activity in the liver.
