Abstract

The present work was carried out on ten of fresh carp fishes with
avarage weight range 1.5 – 3.5 kg. The fishes were subjected to fine
dissection to demonstrate the anatomy of the digestive, respiratory
and urogenital organs. Carp fish had a terminal moth, no any teeth on
both jaws and this was compensated by well-developed pharyngeal
pad and pharyngeal teeth. No stomach could be observed but the
beginning of the intestinal tract formed an intestinal swelling. The
intestinal tract throughout its length formed three U-shaped loops.
The liver was relatively large and formed of multiple hepatic
fragments that surrounded and dispersed between most of the viscera.
The gall bladder was a large sac situated on the right side of the
intestinal swelling. Five pairs of gill arches were observed and the
last pair united forming the pharyngeal bone. The swim bladder was
two chambered and was physostomous type. The kidneys were
differentiated into head and trunk kidneys. The ovaries were large
oval bodies that occupied most of the abdominal cavity. The testes
consisted of 5-6 irregular lobes.
