XI International Symposium on Clinical Anatomy, Varna, Bulgaristan, 02 Ekim 2020
Published data in scientific literature on the anatomy and biology of common stingray (Dasyatis pastinaca) in the
Black Sea are limited. The aim of the present study was to describe the most common variations in the main blood
vessels that are important for respiration and reproduction of this species. For this purpose, 6 stingrays (3 males
and 3 females) with an average body weight of 2533±174 g were obtained from a sea pound trap near the town of
Varna, Bulgaria. After that, fish were sacrificed and the blood vessels were filled through the heart with self-curing castable resin Duracryl® Plus O. In addition, materials from blood vessels for histopathology examination
were taken and fixed in 10% neutral formalin solution. Based on the corrosion cast and histological techniques,
we described the structure and the interrelationships of the vascular pathways. It can be concluded that this study
contributes to a description of the cardiovascular system of common stingray, which could be used to extend the
existing information and contribute to the needs in the various field of biomedical engineering
