Abstract[English]
), a key fish species in global finfish aquaculture. The species demonstrated significant efficacy in improving the health and growth performance of Nile tilapia juveniles. Specific growth rates and weight gain, and improved feed conversion ratios without adverse effects on fish health were observed. The gut microbiome was positively influenced by promoting beneficial bacteria while reducing harmful (opportunistic) species, leading to improved immune modulation. Survival rates were significantly boosted during a pathogenic challenge, and key immune genes were upregulated, indicating stronger local immune defenses. These findings show that the selected probiotic species offer substantial benefits for growth, feed efficiency, and disease resistance, emphasizing their potential for widespread application as probiotics in aquaculture.[French]
), une espèce de poisson clé dans la pisciculture globale. Les espèces ont démontré une efficacité significative dans l'amélioration des performances de santé et de croissance de tilapia du Nil juvéniles. Des taux de croissance et un gain de poids spécifiques, et des rapports d’indice de transformation améliorés sans effets indésirables sur la santé des poissons ont été observés. Le microbiome intestinal a été influencé positivement par la promotion de bactéries bénéfiques tout en réduisant les espèces nocives (opportunistes), ce qui conduit à une modulation immunitaire améliorée. Les taux de survie ont été significativement amplifiés pendant un test de provocation de pathogène, et des gènes immunitaires clés ont été régulés à la hausse, indiquant des défenses immunitaires locales plus fortes. Ces découvertes montrent que l'espèce probiotique sélectionnée offre des avantages sensibles pour la croissance, l'indice de transformation et la résistance aux maladies, accentuant leur potentiel pour une application généralisée en tant que probiotiques en aquaculture.
