BACKGROUND: The northern pike Esox lucius is a fresh water species belonging to the Esocidae family. It is a carnivorous fish which mostly feeds on invertebrates and fishes. The morphology of
its intestine is very useful for understanding the fish's digestive physiology, diagnosing some intestinal diseases and formulating suitable feeds. OBJECTIVES: This study was designed to determine the anatomical, histological and histomorphometric properties of the intestine of E. lucius.
METHODS: The intestines of five E. lucius were examined in this study. After anatomical dissection, the histological specimens were taken and fixed in 10% formalin. Then, tissue passages were stained with hematoxylin-eosin, and Masson's trichrome. CONCLUSIONS: The results of this study revealed adaptation for the species feeding habits, so as to protect the intestine and increase absorptive processes
