has significant ecological and economic value. Research on its digestive physiology provides insights into its ecological conservation and artificial breeding. The histological structure of the digestive tract of was studied using light and scanning electron microscopy. The mucosa of the oropharyngeal cavity stratified squamous epithelium with some goblet cells and taste buds, and many micro-ridges on the surface of the epithelial cells. The mucosa of the esophagus formed abundant folds. Some localized areas of epithelium were composed of simple columnar cells, and there were many large goblet cells. The‘┫’-shaped stomach may be divided into three regions, cardiac, caecum and pyloric. The cardiac and caecum regions contained more gastric glands, while gastric glands were not found in the pyloric and terminal caecum regions. Scanning electron microscopy revealed numerous gastric pits in the gastric internal surface. The intestine of was short (Intestinal Coefficient 0.33), and the number of mucous cells gradually increased from the anterior to the posterior intestine. On the other hand, the number of microvilli and cilia was significantly reduced from the foregut to the hindgut. The sharp teeth, abundant goblet cells in the esophagus, lower intestinal coefficient, and significant stomach-intestine structural differentiation indicated that is a typical carnivorous fish.
