Abstract: (580 Views)

The developing heart is the first organ to begin functioning in fish. The fish heart consists of four chambers in series, the sinus venosus, atrium, ventricle, and conus or bulb. The heart is composed of typical vertebrate cardiac muscle, although there may be slight differences in the distribution of spontaneously active cells, the speed and nature of the propagation of excitation waves, and the characteristics of resting and action potentials between different fish and other vertebrates. Cholinergic fibers innervate the heart, except for the hagfish, which have anorectal hearts. The fish heart lacks sympathetic innervation. The level of vagal tone varies considerably and is influenced by many factors, but this morphology varies in different fish species due to climatic conditions. Therefore, the aim of this study was to investigate the heart of the Barbus grypus fish. In this study, the hearts of 5 Barbus grypus fish were studied for morphology and morphometry. The results showed that the main parts of the heart included the ventricle, atrium, and arterial bulb. The average weight of the whole heart was 0.26, the average length of the atrium was 4.6 mm, the average length of the ventricle was 7.2 mm, and the average length of the arterial bulb was 9.2 mm. Considering the different morphologies of fish hearts in different species, the results of this study can provide useful information to veterinarians, environmentalists, and fisheries experts.
