“…Even in this case, however, the duration of its influence remained limited to 1-2 months when compared to 8-9 months before the appearance of B. ovata (SHIGANOVA et al, 2003(SHIGANOVA et al, , 2004. Regarding its presence in the Sea of Marmara, up to 0, 3 ind.m -3 were found in 2001, resulting in a decrease of the M.leidyi population there (ISINIBILIR et al, 2004). Since then, B.ovata has been observed regularly in this area (ISINIBILIR PERS.…”

A new alien species Beroe ovata Mayer 1912 was recorded in the Aegean Sea. It is most likely that this species spread on the currents from the Black Sea. Beroe ovata is also alien to the Black Sea, where it was introduced in ballast waters from the Atlantic coastal area of the northern America. The species is established in the Black Sea and has decreased the population of another invaderMnemiopsis leidyi, which has favoured the recovery of the Black Sea ecosystem.We compare a new 1 species with the native species fam. Beroidae from the Mediterranean and predict its role in the ecosystem of the Aegean Sea using the Black Sea experience.

“…Following the first record of L. tetraphylla in September 2005 (362 ind./m 3 maximum abundance), there was a constant increase in the abundance in the following Table I. Cnidaria and Ctenophora species reported from Marmara Sea (data from Demir 1952;Shiganova et al 1995;Unsal 1995;Albayrak & Balkis 2000;Inanmaz et al 2003;Isinibilir 2004;Isinibilir et al 2004). …”

“…Nevertheless, to date, information on the diversity and abundance of jellyfish fauna in this area is still scarce. Most researchers noted the occurrence of hydromedusae as an overall taxon, focusing on total hydromedusae abundance, whereas taxonomic attention was paid only to scyphozoans and ctenophores (Shiganova et al 1995;Isinibilir et al 2004). The studies by Demir (1952), Unsal (1995) and Albayrak and Balkis (2000) dealt only with the polyp stage of Hydrozoa.…”

“…Several dramatic changes took place in the last decades in the Marmara Sea associated with anthropogenic stress. More recently, the Marmara Sea ecosystem has been damaged severely by the opportunistic invasions of Mnemiopsis leidyi (Shiganova et al 1995;Isinibilir et al 2004). In general, jellyfish are important consumers of holo-and merozooplankton in many habitats, although their ecological role is poorly appreciated and often under-estimated (Boero et al 2008).…”

This manuscript deals with the first records of five jellyfish species in the Marmara Sea (Turkey) of previously unrecorded medusozoan species (four hydrozoan taxa, Liriope tetraphylla, Aglaura hemistoma, Solmundella bitentaculata, Neoturris pileata, and one scyphozoan, Paraphyllina ransoni) from plankton collections made in the years [2001][2002][2003][2004][2005][2006][2007][2008]. Jellyfish abundances and distribution patterns are reported here, with a discussion about their possible introduction pathways and potential predatory outcomes into the fragile pelagic ecosystem of the Marmara Sea.

“…In the last decade, the Sea of Marmara has been exposed to heavy changes that induce jellyfish bloom and mucilage generation. In the beginning of 1990, the ctenophore Mnemiopsis leidyi was introduced into the Sea of Marmara and it damaged all ecosystems drastically (Isinibilir, Tarkan, & Kideys, 2004). Since then, Beroe ovata, Chrysaora hysoscella, Liriope tetraphylla, Aequorea vitrina and other alien jellyfish species have been introduced to the region, respectively (İnanmaz, Bekbolet, & Kıdeyş, 2002;Isinibilir, Yilmaz, & Piraino, 2010;Yilmaz, Isinibilir, Vardar, & Dursun, 2017).…”

First record of Cotylorhiza tuberculata (Macri, 1778) from the Sea of Marmara

Jellyfishes, which are one of the most important consumers in marine ecosystems, may have detrimental effects on fish stocks that have economic value. Therefore, identifying and monitoring jellyfish presence is important. We observed four individuals of symbiotic rhizostome scyphozoan Cotylorhiza tuberculata in the vicinity of the Princes' Islands Archipelago, in the Northeast Sea of Marmara, Turkey in September 2020. Although this species is a common member of gelatinous plankton in the Mediterranean Sea, the present study is the first record from the Sea of Marmara.
