First Reproduction Record of Planktonic Unarmored Dinoflagellates Ceratoperidinium falcatum (Kofoid & Swezy) Re？é & Salas, 2013 in ？zmir Bay (Aegean Sea)

With the aim of determining the species diversity of unarmoured dinoflagellates, samplings were carried out from 3 stations in ？zmir Bay during June 2017. This study identified unarmoured dinoflagellat species Ceratoperidinium falcatum from the collected material. Ceratoperidinium falcatum abundance varied from 658 to 840 cells L– 1 during this period in sea water temperature at 15.0 ℃ and salinity of 38.6. The width of cell varies from 23.90 to 36.60 μm and the length of cell varies from 92.50 to 239 μm. This paper reports the first bloom record of the Ceratoperidinium falcatum species in the ？zmir Bay (Aegean Sea) and morphological characteristics of this species were given in detail information, distrubition and original photographs
