Histology of Bighead Carp (Hypophthalmichthys nobilis) Intestine

This study addressed the histology of intestine of the bighead carp. The histological characterization of the intestinal wall revealed that it is composed of the tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. It is line by simple columnar epithelium in association with goblet cell, where as the mucosa is thrown into folds (villi). A thin layer of smooth muscle fibers lies between tunica mucosa and submucosa. The tunica muscularis has two layers. Outer layer of intestine is tunica serosa. In the tunica mucosa and submucosa, many eosinophilic granular cells were observed.
