Öğe Decapod Crustaceans associated with the sponge Sarcotragus muscarum Schmidt, 1864 (Porifera: Demospongiae) from the Levantine coasts of Turkey(Iranian Fisheries Research Organization, 2011) Ozcan, T.; Katagan, T.The present study was carried out to determine the Decapod Crustaceans fauna in association with Sarcotragus muscarum Schmidt, 1864 from the Levantine Sea coasts of Turkey studied between 13 September 2005 and 07 October 2005. As a result of the present study, a total of 711 specimens belonging to 12 decapod species were identified. Among the species determined, Synalpheus gambaroloides (Nardo, 1847) was the most dominant species represented with 616 individuals and dominance value of 86.64%. Alpheus rapacida de Man, 1908 is firstly encountered in association with the sponge species.Öğe Expanding distribution and occurence of the Indo-Pacific Stomatopod, Erugosquilla massavensis (Kossmann, 1880) on the Aegean coast of Turkey(Natl Centre Marine Research, 2008) Ozcan, T.; Ates, A. S.; Katagan, T.The indo-Pacific mantis shrimp, Erugosquilla massavensis was recently collected from Sigacik Bay, located on the Aegean coast of Turkey. It is the first record of the species along the Aegean coast of TurkeyÖğe First record of the red shrimp, Aristeus antennatus (Risso, 1816) (Decapoda: Aristeidae) from the Aegean Sea coast of Turkey(Natl Centre Marine Research, 2009) Ozcan, T.; Irmak, E.; Ates, A. S.; Katagan, T.A female specimen of the deep-water red shrimp, Aristeus antennatus (Risso, 1816) was caught at depths of between 550 m and 670 m during 2005 by trawling off the Marmaris coast. A. antennatus is a species known to inhabit only the Levantine Sea coast of Turkey. This paper is on the first record of the species along the southern Aegean Sea coast of TurkeyÖğe Soft-bottom decapod and stomatopod crustaceans of Northern Cyprus coast(Iranian Fisheries Science Research Inst-Ifsri, 2014) Ozcan, T.; Katagan, T.; Kirkim, F.; Bakir, K.[Abstract Not Available]Öğe An updated review of alien species on the coasts of Turkey(Natl Centre Marine Research, 2011) Cinar, M. E.; Bilecenoglu, M.; Ozturk, B.; Katagan, T.; Yokes, M. B.; Aysel, V.; Dagli, E.This 2010 review of alien species along the coasts of Turkey represents a total of 400 alien species belonging to 14 systematic groups. The present paper also reports the first findings of Vanderhorstia mertensi in the Aegean Sea (Gokova Bay), Chama adspersa in the Sea of Marmara and Mya arenaria in the Aegean Sea. A total of 124 new alien species was determined within the last 5 years. Mollusca had the highest number of species (105 species), followed by Polychaeta (75 species), Crustacea (64 species) and Pisces (58 species). The highest number of alien species (330 species) were encountered on the Levantine coast of Turkey, followed by the Aegean Sea (165 species), Sea of Marmara (69 species) and Black Sea (20 species). The Suez Canal (66% of the total number of alien species) is the main vector for species introductions to the coasts of Turkey, followed by the shipmediated transport (30%). The majority of species (306 species, 76% of total number of species) have become established in the area, while 59 species are classified as casual (15%), 23 species as questionable (6%) and 13 species as cryptogenic (3%). One new alien species was introduced to the coasts of Turkey every 4 weeks between 199:1 and 2010. The majority of aliens were found on soft substratum (198 species) in shallow waters (0-10 m) (319 species). Some species such as Caulerpa racemosa, Amphistegina lobifera, Amphisorus hemprichii, Rhopilema nomadica, Mnemiopsis leidyi, Hydroides spp., Ficopomatus enigmaticus, Charybdis longicollis, Rapana venosa, Asterias rubens, Siganus spp. and Lagocephalus sceleratus show a highly invasive character, and have great impacts both on the prevailing ecosystems and humans.
