In a 41-day feeding trial, seabream specimens were fed with experimental aquafeeds containing 10% of the bioactive supplements. These additives consisted of a blend of Nannochloropsis gaditana and Arthrospira platensis biomass, which was utilized as either raw (LB-CB) or enzymatically hydrolyzed (LB-CBplus). A control group received a microalgae-free diet. The results showed that the functional aquafeeds improved the nutritional profile of seabream fillets, increasing protein and PUFA-n3 contents while reducing the atherogenic index, especially for the LB-CBplus treatment. LB-CBplus also enhanced the texture parameters (hardness and chewiness) of fillets during the initial 5 days under cold storage. Regarding skin pigmentation, fillets showed increased greenish and yellowish coloration compared to control fish, mostly attributed to the inclusion of crude algal biomass (LB-CB). Moreover, diets enriched with microalgae additives effectively delayed muscle lipid oxidation processes under refrigeration for up to 12 days, with LB-CBplus exhibiting higher antioxidant effects. These findings highlight the potential of microalgae-based additives to enhance both the nutritional and organoleptic quality of seabream fillets.}, publisher = {MDPI}, keywords = {enzyme hydrolysates}, keywords = {feed additives}, keywords = {fillet quality}, keywords = {finishing diets}, keywords = {microalgal biomass}, title = {Feed Additives Based on N. gaditana and A. platensis Blend Improve Quality Parameters of Aquacultured Gilthead Seabream (Sparus aurata) Fresh Fillets}, doi = {10.3390/FISHES9060205}, author = {Sáez, María Isabel and Galafat, Alba and Tapia Paniagua, Silvana Teresa and Martos Sitcha, Juan Antonio and Alarcón López, Francisco Javier and Martínez Moya, Tomás Francisco}, }
