AB This work aimed to assess the suitability of a microalgal blend as a dietary ingredient forfeeding juveniles of marine carnivorous and herbivorous teleost, as is the case of Sparus aurata andMugil cephalus, respectively, and to isolate microorganisms from different media and characterizethem on the base of their enzymatic activities and their antagonism against important fish pathogens.Thirty juveniles of each species (70   3.2 g S. aurata mean weight and 47   2.8 g M. cephalus meanweight) were distributed in four tanks (15 individuals each) corresponding to four independentdietary treatments (control and microalgae diets designed for each species). Fish were fed theircorresponding diets ad libitum for 108 days. At the end of the trial, fish were weighed, and plasma,liver, perivisceral fat, and the entire intestines were obtained for the evaluation of growth performanceand metabolic assessment. Furthermore, 117 bacterial strains were isolated in different culture mediafrom the gastrointestinal tract of S. aurata fed the microalgae blend and further characterized fortheir potential use as probiotics in aquaculture. S. aurata fed the microalgae-supplemented diet(25% dietary inclusion) showed a significant increase in weight gain, specific growth rate, feedefficiency, hepatosomatic, and intestine length indices. However, growth performance and somaticindices in M. cephalus were not affected by the experimental diets. Plasma samples from S. aurata fedthe microalgal diet revealed higher levels of glucose and triglycerides and a decrease in cortisol levels.No significant differences were found in any biochemical parameters among the experimental dietsin M. cephalus. In conclusion, both species demonstrated a favorable adaptation to the nutritionalformulation employed [...]
