The Comparison Research Of The Digestive System About The Four Fishes

With the continuous improvement of living standards,People fish for food quality and variety of a higher demand.Xenocypris davidi Bleeker, Hypophthalmichthys molitrix,Erythroculter ilishaeformis Bleeker and Monopterus albus are high-quality food fishes,taste delicious,Gradually get consumers favor,In order to understand the shape of their digestive system,organizational structure,the relationship between diet and them.This study anatomy and the use of conventional optical microscopy,To their digestive tract the general shape,a research organization.Results:Xenocypris davidi Bleeker:Oropharyngeal cavity mucosal fold the minimum height,the num is 108.96±31.06,urn,Esophagus and the former had the highest,the num is 752.32±342.85和770.59±364.81μm,Goblet cells after intestinal distribution of the most,the num is 77.80±8.61.Oropharyngeal cavity of the thick layer thickness.the num is 446.52±98.69,um.Hypophthalmichthys molitrix:The maximum height before the intestinal fold,the num is 816.43±141.03μm.After the intestinal goblet cells at least.the num is 2.60±2.01,Oropharyngeal cavity maximum thickness of muscle,the num is 474.45±414.18μm.Erythroculter ilishaeformis before the esophagus and the intestinal mucosa fold the maximum height. 880.84±183.94,716.38±142.91μm.Before and intestinal goblet cells in the gut of the highest density,the num is 57.20±15.76和57.10±15.91.Oropharyngeal cavity and the former had the highest total thickness of muscle,the num is 674.43±65.83and 433.41±35.98μm.The former rice field eel stomach and intestinal fold the maximum height,the num is 609.38±175.71 and 927.40±258.56μm.In the intestines and bowel after the highest density of goblet cells,the num is 118.20±19.12和132.30±25.51.Esophagus and the stomach muscle highest total thickness.the num is 802.54±324.05和339.28±18.76μm.Conclusion:Silver carp gastrointestinal form the organizational structure of a typical structure of Xenocypris davidi Bleeker,Hypophthalmichthys molitrix. Erythroculter ilishaeformis Bleeker and Monopterus albus are Predatory fishes,the size of Oropharyngeal cavity and thickness of muscle in line with their survival needs,Esophagus is the important food storage organs.Before then General intestinal digestion and absorption is the main venue.Intestinal digestion and absorption by the former bowel function after intestinal to gradually reduce.After a strong gut function swallow drink.Main function is to defecation.Goblet cells in the digestive tract is a major role in the lubrication and digestion,the gastrointestinal form of Four fishes and organizational structure are closely linked with their diet.
