Abstract


The basic science is the starting point for applied research. For these reasons, in the present study we have proposed to address some aspects of external conformation and morphology of the digestive apparatus in Danube salmon. This species is less studied from the anatomical point of view, given its status of  rare and strictly protected species. For the restoration of natural stocks, captive breeding and breeding lots are the most effective methods. Inherently, however, captive growth implies appropriate anatomical and physiological knowledge. The present study addresses problems related to anatomical structure and internal topography, sequentially analyzing the segments of the digestive apparatus in the cranial-caudal direction: oral cavity, pharynx, esophagus, stomach, pilorian appendix, middle intestine, rectum and adjacent glands, represented by the liver.
