Alteration of Growth Performance, Antioxidant Capacity, Tissue Fatty Acid Profiles, and Lipid Metabolism of Mud Crab (Scylla paramamosain) Juvenile in Response to Different Dietary Arachidonic Acid Levels

Figure 3

Effects of different dietary ARA levels on hepatopancreas histological structure of mud crab Scylla paramamosain. Histological sections of hepatopancreas are shown in (a) 0.40, (b) 2.50, (c) 4.60, (d) 8.90, (e) 12.50 and (f) 15.70 groups under 400× magnification, respectively. The areas of B cell (a) and R cell (b). Data were represented as mean ± SD of three replications (n =3). Different letters on the error bars indicate significant differences by Tukey’s test (P <0.05). R cell, restzellen cell; B cell, blasenzellen cell; Lu, lumen structure; Bm, basement membrane.
