description 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. Приведены описания 4 видов гименолепидоидных цестод от луговой тиркушки юга Украины: Glareolepis poralae (Meggitt, 1927) Spassky, 1967; Wardium (s. l.) tauricum Kornyushin et Greben, sp. n.; Wardium (s. l.) sp.; Echinocotyloides longirostris (Rudolphi, 1819) Kornyushin, 1983. Детально описана морфология G. poralae. Установлено, что в гермафродитных члениках у G. poralae семенники отсутствуют, а структуры, описанные в литературе как семенники в гермафродитных члениках — это лопасти яичника. Описан новый вид цестод Wardium (s. l.) tauricum sp. n. с аплопараксоидными крючьями 13–15 мкм длиной и конусовидным вооруженным циррусом 20–22 мкм длиной. Еще один вид цестод Wardium (s. l.) sp. из-за отсутствия сколекса определен только до рода. Он отличается от всех известных видов этого рода размерами и вооружением цирруса.

Introduction The Black Sea fauna consists of the group of Mediterranean immigrants which entered this water body probably within the past 12 000 years (Miller, 1965). One of the common representatives of this faunistic group is the marbled goby Pomatoschistus marmoratus (Risso, 1810), which is widely distributed in whole Mediterranean basin (Miller, 1986). Because of their ecological plasticity, the gobiids are a convenient model for studying the processes of colonization by parasites (Zander, Kesting, 1998). In the Black Sea the gobiid parasite fauna is more heterogeneous than the gobiid fish fauna itself (Naidenova, 1974). The specific parasite fauna, which is not similar to the ones of other gobiid species in the Black Sea, is typical for the marbled goby (Kvach, 2005 a). It consists of the specialists such as Aphalloides coelomicola Dollfus, Chabaud et Golvan, 1957 and Paratimonia gobii Pre´vôt et Bartoli, 1967. Vestnik zoologii, 44(6): 509–518, 2010 Ýêîëîãèÿ The aim of the presented study is to analyse the parasite community of the marbled goby and the role of this fish in the parasite life cycles in the Northwestern Black Sea. Material and Methods The gobies were sampled by deep net (100 cm x 50 cm; cell /◎ 5 mm) in 2002–2006 at 8 localities of the Northwestern Black Sea (NWBS): 1. Tyligul Estuary, 46°53' N 31°03' E; 2. Tyligul Estuary, 46°41' N 31°09' E; 3. Tyligul Estuary; 4. Hryhorivsky Estuary, 46°37' N 31°00' E; 5. Khadzhibey Estuary, 46°33' N 30°41' E; 6. Gulf of Odessa, 46°28' N 31°45' E; 7. Sukhyi Estuary, 46°21' N 30°38' E; 8. Budaki Lagoon, 46°01' N 30°24' E (fig. 1). Two water bodies, the Tyligul Estuary and the Budaki Lagoon are isolated from the sea by natural sandbars. The sampling places in the Gulf of Odessa and the Sukhyi Estuary were located in lagoons, artificially isolated from the sea by mooring lines. Only in the Hryhorivsky Estuary the gobies were sampled in the southern part, connected with the open sea. In total, 108 gobies were examined for metazoan parasites (table 1). The fish were transported alive to the laboratory, put in aquarium, and then executed in two days. The standard length (SL, cm) of fish individual was measured first. All parasitological nomenclature follows the levels of Bush et al. (1997) and Zander (1998). The prevalence (P, %), intensity (presented as intensity range, IR), mean intensity (MI), and abundance (A) were calculated according to Bush et al. (1997). The importance of the host-parasite relationship, expressed as the status as core or satellite species, is described by abundance: > 2 — core species, 0.6–2 — secondary species; 0.2–0.6 — satellite species; < 0.2 — rare species (Zander et al., 2000; Zander, 2003). The tendency to join the infracommunity was evaluated according to the Infracommunity Index, ICI (Zander, 2004): , where Mij was the ratio (numbers) of multiple infected hosts j with parasite i and other parasites, Nj was the ratio (numbers) of infected hosts j, and Ij was the mean of parasite species in host j (= mean 510 Yu.

The great tendency to join the community was determined by the ICI level more then 0.30 (Zander, 2004). The Species Evenness (J) was calculated according to Zander et al. (1993): , where Hs is Shannon-Wiener Index, S is number of species. Evenness values > 0.6 mean a greater part of the homogeneity, of > 0.7 a high homogeneity. Abbreviations of names of parasites life stages were used as follows: pl — plerocercoid, met — metacercaria, L3 — 3rd stage larva. Results The maximal number of fishes was caught in the Budaki Lagoon, Khadzibey and Tyligul estuaries (table 1). In the Gulf of Odessa, Hryhorivsky and Sukhyi estuaries the marbled goby was rather rare (5, 7 and 8 fishes respectively). No metazoan parasites occurred in the marbled goby in the Khadzhibey Estuary. All fishes caught in the Budaki Lagoon, Sukhyi and Tyligul estuaries were infected with parasites (table 1). Four from five examined fishes were infected in the Gulf of Odessa, 6 from 7 in the Hryhorivsky Estuary. The maximal number of parasites and abundance were noted in the Budaki Lagoon. In total, 12 metazoan parasite species occurred in the marbled goby in the NWBS (table 2). The component community consisted of 7 digenean species, two nematodes, two acanthocephalans, and one cestode species. Two parasite species (Aphalloides coelomicola and Dichelyne minutus (Rudolphi, 1819)) were presented by both adults and larvae (table 2). Four parasite species were presented by adults, and six by larvae. Most of parasite species, namely Bothriocephalus gregarius Renaud et al., 1983 pl, Asymphylodora pontica (Tschernyschenko, 1949), Paratimonia gobii, D. minutus, Acanthocephaloides propinquus (Dujardin, 1845), and Telosentis exiguus von Linstow, 1901, were found in the gut of fish. Four parasite species, A. coelomicola met, Cryptocotyle concavum (Creplin, 1825) met, C. lingua (Creplin, 1825) met, T. imbuti- forme met, occurred in muscles of gobies. Two species from this list (C. concavum met and C. lingua met) were also found in fins and skin, but one (A. coelomicola met) in ovaries. The parasites located in tissues (metacercariae of A. coelomicola, Cryptocotyle spp., Timoniella imbutiforme (Molin, 1859)) were most numerous in the marbled goby (table 2). Three parasite species were found encysted in intestinal walls: Pygidiopsis genata Looss, 1907 met, D. minutus L3, Contracaecum microcephalum (Rudolphi, 1819) L3. Only adults of A. coelomicola occurred in the body cavity of gobies. Two species, T. imbutiforme met and A. propinquus, occurred in all the water bod- ies studied (table 2). Such parasites as B. gregarious pl, C. microcephalum L3, T. exigu- us were found only in one water body (table 2). 511Parasites of the marbled goby (Pomatoschistus marmoratus)… Ta b l e 1.

In the Sukhyi Estuary and the Budaki Lagoon the secondary species were absent, but in the Gulf of Odessa no satellite and rare species occurred. The core species were found in all water bodies (except the Khadzhibey Estuary where no meta- zoan parasite was found). The number of the core species in the component commu- nity varied from one (in the Hryhorivsky Estuary) to five (in the Sukhyi Estuary and the Budaki Lagoon) (fig. 2).

C. microcephalum and A. propinquus were rare in the Budaki Lagoon. Four parasite species (C. concavum, P. gobii, P. genata, and T. imbutiforme) were core in the Sukhyi Estuary, but A. pontica and A. propinquus were satellite (table 2). In the Gulf of Odessa the digeneans P. gobii, T. imbutiforme, and the nematode D. minutus were core, but the acanthocephalan A. propinquus was secondary species in the parasite communi- ty. Only T. imbutiforme was core in the Hryhorivsky Estuary, B. gregarius and D. min- utus (for adults and larva the summarised A = 1.9) were secondary, C. concavum and T. exiguus were satellite, and A. propinquus was rare. In the Tyligul Estuary C. con- cavum, P. gobii, and T. imbutiforme were core species, A. coelomicola (for adults and larvae the summarised A = 1.2), A. pontica, and C. lingua were secondary, A. propin- quus was satellite, and D. minutus was rare (table 2). In total, in the NWBS the core species were C. concavum, P. gobii, P. genata, and T. imbutiforme, secondary species were A. coelomicola and C. lingua, satellite species were A. pontica, D. minutus, and A. propinquus, other species were rare (fig. 3). The parasite fauna was presented by five types of infracommunities with the species numbers from one to six (fig. 4). In the Budaki Lagoon the parasite fauna was present- ed by all types of infracommunities and most of examined fishes were infected with four and more parasite species. In the Tyligul Estuary most of examined fishes were infect- ed with one to three parasite species. The fishes infected with only one parasite species were relatively rare, from two individuals in the Hryhorivsky and Sukhyi estuaries and the Gulf of Odessa, to six individuals in the Tyligul Estuary. Only one species, T. imbu- tiforme, had great tendency to join the infracommunity in the Tyligul Estuary (table 3). This parasite also had high ICI in other water bodies, except the Sukhyi Estuary, and maximal tendency to join the community for the total NWBS (ICI = 0.29). The greater part of the homogeneity of the parasite component community was mentioned in the Gulf of Odessa, Hryhorivsky, and Tyligul estuaries (table 2). In the 514 Yu. Kvach Fig. 3.

In total, the low homogeneity was typ- ical for the parasite component community of the marbled goby in the NWBS. Discussion Twenty-seven metazoan parasite species have been mentioned in the Black Sea basin according to data of different authors (Radulescu, 1953; Chernyshenko, 1960, 1962, 1966; Chernyshenko, Sventsytskaya, 1970; Naidenova, 1974; Machkevsky et al., 1990). We found 17 parasite species, 15 of which had already been mentioned in pub- lished data, but two species, Àsymphylodora pontica and Ñryptocotyle lingua met, were mentioned from the marbled goby for the first time. The absence of metazoan parasites in the Khadzhibey Estuary was caused by its low salinity (~ 3‰). All of parasites typical for the marbled goby have marine or brack- ish water origin. The absence of digeneans, which are core of the marbled goby para- site fauna, was caused by lack of mollusks in the fauna of the Khadzhibey Estuary (Kvach, 2004). The relative abundance of the various parasite species was the highest in the Gulf of Odessa, where the species richness was the lowest (table 2). All parasite species in this water body, except Paratimonia gobii, had similar tendency to join the communi- ty, ICI = 0.25 (table 3). The digenean Asymphylodora pontica is a specific parasite of gobiids in the Black Sea, infecting mostly neogobiins, such as the round goby Apollonia melanostoma, and the monkey goby A. fluviatilis (Gaevskaya et al., 1975; Kvach, 2005 a). However, the case of infestation of gobiin fish (a grass goby Zosterisessor ophiocephalus from the Hryhorivsky Estuary) was mentioned by Yu. Kvach (2005 b). In both cases (occurrence in the marbled and grass gobies) we can consider it as an occasional infestation. 515Parasites of the marbled goby (Pomatoschistus marmoratus)… Fig. 4.

The marbled goby plays important role in the realization of the life cycle of the cestode Botriocephalus gregarius and the digenean Timoniella imbutiforme. Both species are generalists on the larval stage. In the Mediterranean Sea B. gregarius uses the mar- bled goby as main paratenic host, but the definitive host is the turbot Psetta maxima (Robert et al., 1988). In the NWBS this species occurred in the Hryhorivsky Estuary only. This is a water body connected with the sea by 15-m depth navigation canal, which is a suitable habitat for turbots. The T. imbutiforme met is a numerous parasite species occurring in all the water bodies examined (table 2). This is only parasite species which has great tendency to join the infracommunity, but only in the Tyligul Estuary, where the highest diversity of parasites was noted according to the Shannon Index (table 2, 3). The gobiids serve as second intermediate hosts of this parasite, together with other small-sized fishes, such as Atherinidae (Maillard, 1973 a). The marbled goby is an annual fish species, which dies after spawning (Miller, 1986; Smirnov, 1986). The small sizes of this fish makes it the suitable pray item for many species of predatory fish and fish-eating birds. This fact influents the parasite fauna of this goby. So, the core species in the parasite component community are most- ly metacercariae, such as Cryptocotyle spp., Pygidiopsis genata, T. imbutiforme (table 2). Also, in the core of the parasite fauna are two parasites specific for genera Pomato- schistus and Knipowitschia: Aphalloides coelomicola and P. gobii (table 2). The marbled goby plays a role of both definitive and second intermediate host for A. coelomicola (Maillard, 1973 b). The adults are located in the body cavity, and the metacercariae are in the ovaries and muscles of the same fish. This parasite is well adapted to the life cycle of the gobies and the necessary condition for the transmission of the digenean is the host death (Pampoulie et al., 2000). The infestation of Pomatoschistus with P. gobii is a case of adaptation of the parasite life cycle to the specific diet of the host. The metacercariae of P. gobii are located in inhaling siphons of mussels Abra ovata and Cerastoderma glaucum (Maillard, 1975). The small-sized gobies, such as the marbled goby, can use the cut-off siphons as the pray item. So, among the core species of the parasite fauna of the marbled goby in the stud- ied NWBS lagoons and estuaries are not only generalists, as Cryptocotyle spp. or T. im- butiforme, but also specialists, such as A. coelomicola and P. gobii. Both specialists have Mediterranean origin, as well as their hosts. This is a marked difference between the marbled goby and other Black-Sea gobiids, the core of which parasite fauna consists of generalists only (Kvach, 2005 a; Kvach, Og � uz, 2009). The infestation of the marbled goby with two above mentioned specialist trematode species is a result of co-evolution, 516 Yu. Kvach Ta b l e 3. Infracommunity indices Ò à á ëèö à 3.

It was a cause of successful co-immigration of the marbled goby and its specific parasites to the Black Sea. Bush A. O., Lafferty K. D., Lotz J. M., Shostak A. W.

Helminths of the Marbled Goby (Pomatoschistus marmoratus), a Mediterranean Immigrant in the Black Sea Fauna / Yu. Kvach // Вестник зоологии. — 2010. — Т. 44, № 6. — С. 509–518. — Бібліогр.: 28 назв. — англ.

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.
Приведены описания 4 видов гименолепидоидных цестод от луговой тиркушки юга Украины: Glareolepis poralae (Meggitt, 1927) Spassky, 1967; Wardium (s. l.) tauricum Kornyushin et Greben, sp. n.; Wardium (s. l.) sp.; Echinocotyloides longirostris (Rudolphi, 1819) Kornyushin, 1983. Детально описана морфология G. poralae. Установлено, что в гермафродитных члениках у G. poralae семенники отсутствуют, а структуры, описанные в литературе как семенники в гермафродитных члениках — это лопасти яичника. Описан новый вид цестод Wardium (s. l.) tauricum sp. n. с аплопараксоидными крючьями 13–15 мкм длиной и конусовидным вооруженным циррусом 20–22 мкм длиной. Еще один вид цестод Wardium (s. l.) sp. из-за отсутствия сколекса определен только до рода. Он отличается от всех известных видов этого рода размерами и вооружением цирруса.
