Abstract : The study is based on 32 samples of organic fouling obtained from nine vessels navigating in the Sea of Azov, Kerchenskiy proliv (K. Strait), and the Black Sea. As a consequence, 32 species and three subspecies of algae, which constitute the main biomass of organic fouling, are identified. As to the quantity and geographical distribution, the green algae, which are able to endure sharp variations in salinity and turbidity of water, predominate; and they are found as far as Taganrogskiy zaliv (T. Gulf) in the northern section of the Sea of Azov. The percentage of brown and red algae decreases in the direction from Kerchenskiy proliv to Taganrogskiy zaliv. Also, the characteristics in the distribution of organic fouling over the hull of the vessel have been investigated, pointing out the areas preferred by algae and by animals; namely: the illuminated places along the waterline with large quantities of algae and the shaded places along the bottom of the vessel fouled by animals, and the intermediate zone inhabited by both. In addition, the epiphytal phenomena characterized by certain algae growing on others without parasitic relationship are discussed, pointing out the typical representatives of the group such as Acrochaetium Daviesii, A. strictum, Kylinia parvula, K. hollandica.
