Preliminary studies of cultivated phytoplankton microalgae were carried out in water samples collected during four expeditions at oceanographic stations of the coastal waters of the northwestern and northeastern parts of the Black Sea in different seasons of 2019-2020. Some features of the development of the algological component in conditions of changing oceanological characteristics of the environment have been established. In spring, the most active growth of diatoms was revealed in the area from Balaklava to the water area of the Sevastopol Bay.

The status of breeding pelicans and cormorants is assessed in the area from the Danube delta (Romania) to the northern part of the Crimean peninsula. Four breeding species occur in inland and coastal wetlands: Dalmatian Pelican Pelecanus crispus, Great White Pelican Pelecanus onocrotalus, Great Cormorant Phalacrocorax carbo and Pygmy Cormorant Phalacrocorax pygmeus. Data on clutch size and breeding success are given. Historically, all four species were restricted to the Danube delta. Currently, with the exception of Dalmatian Pelican, they all breed successfully on the eastern Black Sea coast in the Ukraine. There are many conservation problems that will jeopardize the breeding of these species in the future if nothing is done.

Morphological descriptions of two species of the genus Theristus Bastian, 1865 belonging to group flevensis, found in the hypersaline water bodies of the Crimean Peninsula, are presented. Theristus siwaschensis sp. n. is morphologically closest to T. flevensis Schuurmans Stekhoven, 1935, T. parambronensis Timm, 1952, T. macroflevensis Gerlach, 1954, T. metaflevensis Gerlach, 1955, but differs from them by the structure of the reproductive system in females, number of cephalic setae and size of spicules. Specimens of T. flevensis found in the Lake Chersonesskoye are similar to the re-description of a large forms of T. flevensis from Chile by Murhy (1966) and Caspian Sea by Chesunov (1981). However, it differs from the Caspian Sea species by having larger amphids, longer cephalic setae and spicules. T. pratti Murph & Canaris, 1964 and T. ambronensis Schulz, 1937 are synonymized with T. flevensis.

Barbus anatolicus, new species, is described from the Kızılırmak and Yeşilırmak River drainages in the southern Black Sea basin. It is distinguished from other Barbus species in the Middle East by having 58–71 total lateral line scales, a moderately ossified last simple dorsal-fin ray, serrated along about 70–80% of its posterior margin, many small irregular shaped black or brown spots, smaller or as large as scales, often forming large, dark-brown blotches on the head, back and flank in adults and juveniles, and a concave posterior dorsal-fin margin. In addition, DNA barcode data reject the hypothesis that it belongs to one of the other species of the B. barbus species group. Barbus bergi from Bulgaria and adjacent Turkey is treated as synonym of B. tauricus. Barbus tauricus was previously believed to be restricted to the Crimean Peninsula but is found to be widespread in the Black Sea basin.

Seascape complexes are decisive in choosing of technologies for growing different species of fish and mollusks, as well as in designing and installing farms on the Black Sea shelf. Marine farms, as hydrotechnical installations, play the role of artificial underwater seascapes and have a mutual influence on natural local systems. This article describes the main elements of mussel-oyster farms, the criteria for choosing a location for them, technological solutions of anchor systems, taking into account the peculiarities of the marine seascapes of the Crimean peninsula. In the Black Sea, it is advisable to install farms of the long-line type, which satisfy almost all the requirements for growing mollusks: they are quite stable during strong storms and wind impacts, allow changing the depth of mollusk placement if necessary, and are easy to install and maintain. The depths at the site which was selected for the installation of the marine farm should be in confines 10...30 m, and 15...20 m is the optimal depth for it. The permissible depth must be at least 10 m under the marine farm in consequence. The choice of optimal depths is associated with the need to save materials also. The characteristics, applicability and installation features of several types of anchors (concrete, screw and plow) for grounds of different composition and density are proposed. Promising areas for the development of the Black Sea mariculture are the western and eastern coasts of the Crimean peninsula.
