    Taxonomy and description of the three marine cyanophycean algae from the Mediterranean Sea; [Türkiye'nin Akdeniz Kıyılarında Yayılış Gösteren Üç Mavi-Yeşil Alg Türünün Tanımlanması ve Taksonomisi]
    (Central Fisheries Research Inst, 2010) Kurt O.; Ulcay S.; Taşkin E.; Öztürk M.
    In the present study, three marine Cyanophycean species from the Mediterranean are reported and described. These species were: Phormidium boryanum (Bory ex Gomont) Anagnostidis and Komárek (1988), Oscillatoria sancta f. caldariorum (Hauck) Lagerheim and Elenkin (1949) and Lyngbya anomala (C.B.Rao) Umezaki and Watanabe (1994), all members of the Oscillatoriales. The samples were collected from mid-littoral zones of Dikili Gulf (Aegean Sea, Turkey). The samples were kept in jars, fixed in 4% formaldehyde-sea water. The algae were identified under the microscope, mounted directly between lam and lamel. Current literature sources were used for the determinations. The photographs were taken using normal microphotography techniques. Data concerning distribution, morphology and ecology of each species are also given. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.

    The red algal genera laurencia, osmundea and palisada (rhodomelaceae, rhodophyta) in Turkey; [Türkiye'de ki{dotless}rmi{dotless}zi{dotless} alg cinsleri laurencia, osmundea ve palisada (rhodophyta, rhodomelaceae)]
    (Central Fisheries Research Inst, 2013) Taşkin E.; Sukatar A.
    In this paper, 12 taxa at specific and infraspecific level of the red algal genera Laurencia (7), Osmundea (2) and Palisada (3) are studied and evaluated from Turkey. Laurencia minuta Vandermeulen, Garbary & Guiry subsp. scammaccae G. Furnari and Cormaci is reported for the first time, and Laurencia uvifera (Forsskål) Børgesen is reported for the second time in Turkey. L. minuta subsp. scammaccae was collected at a depth of 10 m from the Iskenderun Gulf (the Mediterranean coast of Turkey). © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.

    Modern dinoflagellate cyst assemblages of aliağa and nemrut bay: Influence of industrial pollution; [Endüstriyel kirliliğin etkisindeki aliağa ve nemrut körfezi modern dinoflagellat kist topluluğu]
    (Central Fisheries Research Inst, 2015) Aydın H.; Yürür E.E.; Uzar S.; Küçüksezgin F.
    The spatial distribution of modern dinoflagellate cysts was studied, with the purpose of understanding the impact from industrial pollution and sediment characteristics. Eight surface sediment samples were collected to analysis of the spatial distribution of dinoflagellate cysts from two industrially polluted areas: Aliağa and Nemrut Bay (Eastern Mediterranean). A total of 42 dinoflagellate cyst morphotype were identified and total cyst abundance ranged between 11 and 2543 cyst g-1 dry weight sediment at sampling points. The cyst assemblages were represented by cyst of Gymnodinium nolleri, Alexandrium affine type and Lingulodiniumma chaerophorum. The higher cyst concentration was recorded at mostly Aliağa Bay stations however the higher cyst diversity was found at Nemrut Bay stations. Total cyst concentration and autotrophic cyst concentration indicated metal pollution in the sampling areas whereas total number of cysts had no correlation with any metal levels in the sediment except Cr. The distribution of dinoflagellate cysts also showed correlation with sediment structure in Aliağa and Nemrut Bay. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey.

    Daphnia magna as a test species for toxicity evaluation of municipal wastewater treatment plant effluents on freshwater cladoceran in turkey
    (Central Fisheries Research Inst, 2015) Koçbaş F.; Oral R.
    Aquatic toxicity of municipal wastewater was evaluated in an acute toxicity test using water flea, Daphnia magna as an freshwater aquatic experimental animal model. Toxicity test were performed on samples of both untreated (raw) and treated wastewaters were collected Manisa municipal effluents. Undiluted untread and treated effluents were very toxic to D. magnaand cause to death of all exposed daphnids. Dilution of wastewaters was observed to decrease percentage of influence of biological toxicity based on dilutional rate. Acute toxic effect of untreated wastewater on D. magnawas more than that of treated wastewater. In addition, the longer the period of exposure to D. magna, the more significantly toxic effect increased. © Published by Central Fisheries Research Institute (CFRI) Trabzon.
