Transmission Electron Microscopy of the Gastrointestinal Tract of Nile Perch Lates niloticus

The ultrastructure of the gastrointestinal tract of Nile perch was described using Transmission Electron Microscopy standard procedures. Investigations revealed the presence of mucous cells, blood vessels and oil droplets plus several nerve cells and muscle bundles in the oral cavity. Further observ...
