Nematode and acanthocephalan parasites of marine fish of the eastern Black Sea coasts of Turkey

Untitled

“…Among nematodes, H. fabri and H. aduncum showed consistently high prevalence as they were found commonly in Mullus surmuletus and M. barbatus in the Mediterranean Sea (Radujkovic & Raibaut, 1989;Le Pommelet, Bartoli & Silan, 1997;Carreras-Aubets et al, 2012). Moreover, several fish species have also been reported to act as intermediate and/or paratenic host for H. fabri and H. aduncum in the Mediterranean and Black Sea (Carreras-Aubets et al, 2012;Tepe & Oğuz, 2013). In the present study, seasonal changes in the prevalence of Hysterothylacium spp., Capillaria sp.…”

Seasonality and host-parasite interrelationship ofHysterothylacium aduncum(Nematoda) in whitingMerlangius merlangusoff the southern and northern coasts of the Black Sea

“…Overall infection values determined in the present study were about 3 times higher in Sinop samples than that of Balaklava Bay samples, and the differences between localities were statistically signifi cant. Previous studies (see Table 1 for details) on H. aduncum infections in M. merlangus in Sinop coasts of the Black Sea reported high infection prevalence levels from 37.5 % to 100.0% and mean intensities from 3.8 to 12.8 per infected fi sh (Özer et al, 2000;Özer et al, 2009;Özer & Olguner, 2013;Tepe & Oğuz, 2013;Pekmezci et al, 2013). Skuratovskaya et al (2013) reported infection prevalence levels of H. aduncum ranging between 46 -65 % and 1 -12 per infected M. merlangus collected from Crimean coast of the Black Sea.…”

“…Predatory fi sh, like gadoids, largely acquire and accumulate different stages of H. aduncum by ingesting crustaceans, chaetognaths and small fi sh species that are infected and serve as carriers (Klimpel et al, 2003;Klimpel & Rückert, 2005).Whiting is a commercially important fi sh species and widely distributed in the eastern North Atlantic Ocean, the northern Mediterranean, western Baltic and the Black Sea (ICES, 2006). It is particularly distributed along Romanian, Bulgarian, Turkish, Ukrainian, Russian and Caucasus coasts in the Black Sea (Burdak, 1960;Svetovidov, 1964;Gönener & Bilgin, 2010;Özer et al, 2014). The objective of the present study is to investigate the infection levels of H. aduncum in M. merlangus from the southern and northern Black Sea coasts and to provide fi rst detailed comparative ecological analysis of H. aduncum infection of whiting at both localities.…”

“…Hysterothylacium aduncum (Rudolphi, 1802) is a generalist nematode registered from many marine fi sh species (Andersen 1993) and it occurs in around 30 fi sh species, including the whiting, Merlangius merlangus (L., 1758), in the Black Sea (Kornyychuk & Zavjalov, 2005;Özer, 2007;Gaevskaya et al, 2010;Özer et al, 2012;Özer & Olguner, 2013;Tepe & Oğuz, 2013). It lives as sexually mature adults in the digestive tracts of marine teleost fi shes (Navone et al, 1998) and its larvae are known to occur in marine invertebrates and in fi sh (Koie, 1993).…”

Pathology and molecular identification of Anisakis pegreffii (Nematoda: Anisakidae) infection in the John Dory, Zeus faber (Linnaeus, 1758) caught in Mediterranean Sea

“…Anisakis pegreffii is the most frequently isolated in many fish species from Mediterranean waters and appears to be responsible for many cases of human anisakiasis (9). In Turkey, A. simplex and A. pegreffii were morphologically identified different fish species (1,16); while A. pegreffii was molecularly detected in Trachurus trachurus (17). Moreover, A. simplex was morphologically found in Z. faber from the coastal waters of Gökçeada (1).Nematodes of genus Anisakis parasitize a wide range of marine hosts with marine mammals, especially cetaceans, serving as definitive hosts, while fish, squid and other invertebrates serve as paratenic or intermediate hosts.…”
