Comparative histochemical studies of iron absorption in three fresh water teleosts.

Absorption of iron in the intestine of three different species of fishes, namely; Claris batrachus, Channa striatus and Esomus danricus has been described. These three species of fishes have different feeding habits, being omnivorus, carnivorus and herbivorus respectively. The absorption of iron has been studied at different time intervals; after three hours, six hours and nine hours. The mucosal epithelial cells, submucosal blood vessels and blood capilaries were the main site of iron absorption. A comparative account of absorption of iron of all three fishes is described and discussed.
