Liver sections (H&E staining) of diploid (A–C) and triploid (D–F) Atlantic salmon. The images show various degrees of vacuolization (arrowheads) in hepatocytes at fry (A,D) and parr (B,E) stage, and a compact cellular histology with glycogen granules (arrows) at smolt stage (C,F). Scale bars represent 50 µm.
