Abstract: The article discusses the morphology of the brain carp fish on the example of Cyprinus carpio L. We have studied the brain of a sample of male mirror carp and described a method for dissecting and analyzing the morphological structure of different brain regions of this animal. The results of weighing parts the brain and weight ratios to the total body mass and the mass of the brain. We found that with a body weight of 863 ± 135 g, the brain Cyprinus carpio L. weight is 1,10 ± 0,13 g. The mass fraction of the brain in the body of Cyprinus carpio L. is 0,13 %. The maximal values of the mass fraction are the medulla, the unpaired cerebellum and the midbrain. The average mass of the medulla is 0,41 ± 0,07 g (39 %), the midbrain is 0,36 ± 0,05 g (30 %), and the cerebellum is 0,15 ± 0,04 g (13%). The encephalization rate was 0,043, which indicates a fairly high degree of organization of the brain Cyprinus carpio L. within the group lower vertebrates in general and the Teleostei superorder.
Key words: comparative morphology, encephalon, brain, fish, Ostariophysi, carp, behavior, evolution.
