About the possibility of iron absorption by fishes and its pathological action

1. Iron, when absorbed in large quantities by the digestive tract of fishes, can produce in various organs internal lesions which can be histologically and histochemically detected. 2. These lesions are sufficient to lead to death. 3. Such lesions are very similar to those found either in iron-poisoned human beings or in mammals iron-poisoned for experimental purposes. 4. To the above lesions is added, for fishes a more or less pronounced degeneration of the branchial epithelium
