Two New Copepods of the Genus Acartia (Copepoda, Calanoida, Acartiidae) from the Coastal Sea of the South-Western Crimea (Black Sea)

Acartia mollicula Pavlova et Shmeleva, sp. n. and A. eremeevi Pavlova et Shmeleva, sp. n. are described and figured. The copepods were found in zooplankton samples collected by the Juday net from 0-10 m depth in the coastal sea water of Martyn Bay, Sevastopol. Though the new species, A. mollicula and A. eremeevi, are similar to A. clausi ("small" form), A. margalefi Alcaraz and another Acartia from Black Sea they have smaller body size, different structure and armature of the fifth legs, and correlation between length/width of prosome and urosome,; besides, A. mollicula have the rostrum.

Helminths of the Marbled Goby (Pomatoschistus Marmoratus) a Mediterranean Immigrant in the Black Sea Fauna

The marbled goby, Pomatoschistus marmoratus (Risso, 1810), the Mediterranean immigrant in the Black Sea fauna, was examined for the metazoan parasites. In total, 12 parasite species were found to occurre. The component community consists of 7 trematode species, two nematodes, two acanthocephalans, and one cestode species. Two parasite species (Aphalloides coelomicola and Dichelyne minutus) were represented by both adults and larvae, four parasite species were presented by adults (Asymphylodora pontica, Paratimonia gobii, Acanthocephaloides propinquus, and Telosentis exiguus), and six species were presented by larvae (Bothriocephalus gregarius, Cryptocotyle concavum, C. lingua, Pygidiopsis genata, Timoniella imbutiforme, and Contracaecum microcephalum). T. imbutiforme has the great tendency to join the infracommunity. The core of parasite fauna of the marbled goby consists of two specialists, A. coelomicola and P. gobii, which immigrated to the Black Sea together with their hosts. The co-immigration is a result of co-evolution of the parasites' and host's life cycles.

Deep-Water Benthic Polychaetes (Vigtorniella Zaikai and Protodrilus sp.) in the Black Sea as Indicators of the Hydrogen Sulfide Zone Boundary

The Black Sea hypoxic layer, situated near the boundary of the hydrogen sulfide zone, is inhabited by the polychaetes Vigtorniella zaikai, Kisseleva, 1992 and Protodrilus sp., which can serve as indicators of the interface between oxic and anoxic water. The maximum number of polychaetes in the northern part of the Black Sea occur at a depth of 150 m, while near Bosporus, where the flow of the Marmara Sea water enters the Black Sea, the peak depth varies from 150 to 250 m.


We report 7 new prey fishes in diet of the Black Sea bottlenose dolphins Tursiops truncatus (Montagu, 1821) and the first records of 9 prey items from their stomach contents: herring (Alosa sp.), sand smelt (Atherina sp.), horse mackerel (Trachurus mediterraneus), picarel (Spicara flexuosa), Mediterranean sand eel (Gymnammodytes cicerellus), Atlantic stargazer (Uranoscopus scaber), garfish (Belone belone), gobies (Gobiidae indet.) and blennies (Blenniidae indet.). Th e Atlantic stargazer was recorded as a prey species for the common bottlenose dolphin for the first time. Th e horse mackerel and the picarel, formerly recorded in the diet of Mediterranean bottlenose dolphins, now were frequently found in the examined Black Sea dolphins. Th e list of prey fishes for Black Sea bottlenose dolphins now includes 23 items, with many small pelagic and demersal fishes, and it is similar to that of Mediterranean dolphins. Whiting (Merlangius merlangus) is still an important prey species, as 50-70 years ago, whereas turbot (Psetta maeotica), not recorded by us, could lose its importance due to population decline. As before, red mullet (Mullus barbatus) is recorded in winter feeding. Feeding on mullets (Mugilidae) is not a universal trait, and it is possibly restricted to local geographical areas.


The parasite fauna of gobiid fish of the Sukhyi Lyman, Black Sea, is described. Seventeen species of parasites are registered in the gobiids in the water body. The marine tubenose goby Proterorhinus marmoratus has the richest parasite fauna (12 species), the grass goby Zosterisessor ophiocephalus has the fewest number of parasite species (5 species). The microsporidian Loma sp. and ciliate Trichodina domerguei are recorded for the first time for gobiids in the north-western Black Sea. The core of the parasite fauna is formed by metacercariae Cryptocotyle spp. The core, secondary, satellite, and rare species in the parasite community of each host are described. Not only marine and brackish water parasites, but also limnetic species, namely metacercariae D. spathaceum, were registered in the Sukhyi Lyman that differentiates it from the many of localities in the north-western Black Sea.


Conchological Variability of Anadara inaequivalvis (Bivalvia, Arcidae) in the Black-Azov Sea Basin. Anistratenko, V. V., Anistratenko, O. Yu., Khaliman, I. A. - An alien species in the Black Sea and the Sea of Azov - Anadara inaequivalvis (Bruguiere, 1789) - was recently discovered to have a wide range of shell variability. From the investigated samples (over 900 valves) six basic types of the shell commissural opening were defined; they are not, however, discrete conditions. Th e presence of intermediate variants reveals a gradual (continuous) character of the shell variability and indicates that all the samples investigated belong to the same species. Th e variation of some other Anadara characteristics is also discussed, including: quantity and ornamentation of the ribs on the surface of the valves, quantity of chevrons on the ligament area, shape of the hinge plate and quantity of hinge teeth. A comparison of conchological characteristics of Anadara from the Black-Azov Sea Basin with A. inaequivalvis from southeast India shows that ranges and patterns of shell variability of Azov-Black Sea Anadara correspond to variability of A. inaequivalvis from this species type locality - Coromandel Coast of India.


The freshwater bryozoan Pectinatella magnifica (Leidy, 1851) was found for the first time in the Ukrainian part of the Danube Delta (Poludionniy arm, 45°25.00˝ N, 29°45.25˝ E) in 2005. Since then, it has increased in abundance. Th e greatest colony numbers occurred on both dead and living reed stems in the delta region 1.5-2.0 km upstream from the Black Sea.

New Information on the Hosts and Distribution of the Marine Fish Leeches Trachelobdella Lubrica and Pontobdella Muricata (Clitellata, Hirudinida)

Fish leeches collected in the Aegean Sea, the Sea of Marmara and the Black Sea were examined. Trachelobdella lubrica (Grube, 1840) was recorded for the first time from the ballan wrasse Labrus bergylta (Osteichthyes, Labridae), marine bream Diplodus vulgaris (Osteichthyes, Sparidae) and the grouper Epinephelus aeneus (Osteichthyes, Serranidae) from aquiculture. The leeches of this species were found in the Aegean Sea and the Sea of Marmara on the body surface, in the mouth and gill cavities of their hosts. Leeches identified as Pontobdella muricata (Linnaeus, 1758) were collected from the thornback ray Raja clavata (Chondrichthyes, Rajidae) in the Black Sea.

Two New Families and a New Species of Myxosporeans (Myxozoa, Myxosporea) of the Mediterranean and Black Sea Fishes

Descriptions of two new families — Polysporoplasmidae fam. n. (Syn. Sphaerosporidae Davis, 1917 in Sitja-Bobadilla, Alvarez-Pellitero, 1995) and Gadimyxidae fam. n. (syn. Parvicapsulidae Schulman, 1953 in Kie et al., 2007), and one new species of myxosporeans — Gadimyxa ovale sp. n. — parasites of fishes of the Mediterranean and the Black Seas are presented. Species of the genus Gadimyxa is found for the first time in the Black Sea.
