Identification of intestinal microbial population structure of <i>Penaeus vannamei</i> supplemented with chitosan oligosaccharide using 2bRAD-M
This study demonstrates that dietary chitosan oligosaccharide (COS) supplementation can effectively modulate the intestinal microbiota of <i>Penaeus vannamei</i>. At 5‰ and 10‰ levels, COS increased beneficial bacteria (e.g., Bacteroidetes and Actinobacteria) while reducing harmful pathogens like <i>Vibrio parahaemolyticus</i> and <i>Vibrio rotiferianus</i>. This shift enhances nutrient absorption, immune function, and disease resistance in shrimp. COS thus offers a sustainable alternative to antibiotics in aquaculture, promoting healthy growth and reducing environmental impact.
