Electron microscope images obtained from the distal intestine of sea bass fed with diet T. a The enterocytes show long microvilli, an apical tubulo-vesicular system (white arrowhead), and some vacuoles. Between enterocytes, a Goblet cell is observed. b An enterocyte vacuole containing lamellar body (white arrowhead) is visible. c Epithelium with well-developed microvilli covered by mucus (black arrow), a tubulo-vesicular system (white arrowhead), and supranuclear vacuoles. v vacuoles, m microvilli, Gc Goblet cell. Bar in a 10 μm; bars in b, c 200 nm
