Liu Jianhu Ye Yuantu Wang Xuewen Luo Zuzheng (Department of Fisheries,Southwest Agricultural University,Chongqing 400716)  
The nutrition-mixed period of larval Silurus soldatovi meridionils Chen is from day 7~10 after the larvae are hatched when the water temperature is (15.5±0.5) ℃.From 3rd day on,the epithelial cells of intestine begin to differentiate into 3 types of cells till day 6,which are absorbing cells,absorbing-secreting cells and exocrine cells.The digestive tract participates in the absorption of yolk at its early developmental stage.The structure of the tract wall develops incompletely at prelarval and larval stages when its ability is poor in mechanical digestion.
