Effects of Dietary Carbohydrate Levels on the Growth and Glucose Metabolism of Juvenile Swimming Crab, Portunus trituberculatus

Figure 4

Effects of different dietary carbohydrate levels on hepatopancreas histological structure of Portunus trituberculatus. R: R (restzellen) cell; B: B (blasenzellen) cell; F: F (fibrous) cell; Lu: lumen structure; SB: striated border. Areas of B cell, number of B cell, and number of R cell are calculated. D1: 0.0 g kg-1 carbohydrate level; D2: 60.0 g kg-1 carbohydrate level; D3: 120.0 g kg-1 carbohydrate level; D4: 180.0 g kg-1 carbohydrate level; D5: 240.0 g kg-1 carbohydrate level; D6: 300.0 g kg-1 carbohydrate level. Values were expressed as the means of three replicates. Means in each bar with different superscript letters were significantly different ().
