Harmful Algal Blooms (HABs) and Black Mussel Mytilus galloprovincialis (Linnaeus, 1758) Culture in Izmir Bay (Iskele-Urla)-Turkey: Preliminary Results on the Annual Feeding Cycle Using a Qualitative Approach ArchiMer
Lok, Aynur; Metin, Gulnur; Acarli, Sefa; Goulletquer, Philippe.
Considering the filtration capacity of mussels to qualitative particle selection, our study focused directly on ingested species by assessing mussel stomach content of various size classes (1-5 cm) over a year (August 97-June 98) rather than monitoring seawater samples. Different size of mussels (1, 2, 3, 4, 5 cm in length) was sampled monthly from the sides of fish cage floats in Urla-Izmir. Stomach contents were analyzed under microscope and different plankton species were grouped taxonomically. Bacillariophycea, Dinophyceae, Oxyphceae, Euglenophyceae as phytoplanktonic species were observed in the stomach contents of mussels as well as zooplanktonic species including Ciliata, Cladocera, Copepod, bivalve and gastropod larvae. Over the sampling period,...

Late Holocene multisource material input into the Aegean Sea: depositional and post-depositional processes ArchiMer
Giresse, P; Buscail, R; Charriere, B.
The upper similar to50 cm sediments in the deep-sea Aegean Sea were generally deposited through hemipelagic rain as indicated by paucity of terrigenous sand-sized particles, abundance of clay-sized materials and lack of turbiditic beds. However, quartz sand-sized grains, black debris, higher C org content and ON ratio attest to a significant river-borne supply in the North Aegean Trough. Recurrent gravity-induced transfers from the shelf break are evidenced through various markers of coastal deposition dating back the last low-stand (Characea oogons, Elphidium crispum, Ammonia beccarii, glauconitic grains, evolved organic matter). Especially, this deposition induced significant rise of the C/N ratio of successive layers. The top of ash layers of the Minoan...

Marine invertebrate diversity in Aristotle’s zoology Naturalis
Voultsiadou, E.; Vafidis, D..
The aim of this paper is to bring to light Aristotle’s knowledge of marine invertebrate diversity as this has been recorded in his works 25 centuries ago, and set it against current knowledge. The analysis of information derived from a thorough study of his zoological writings revealed 866 records related to animals currently classified as marine invertebrates. These records corresponded to 94 different animal names or descriptive phrases which were assigned to 85 current marine invertebrate taxa, mostly (58%) at the species level. A detailed, annotated catalogue of all marine anhaima (a = without, haima = blood) appearing in Aristotle’s zoological works was constructed and several older confusions were clarified. Some of Aristotle’s “genera” were found to...

Marine Sediment Contamination and Toxicity in Izmir Bay and Mytilene Harbor (Aegean Sea) ArchiMer
Oral, Rahime; Kostopoulou, Maria; Guida, Marco; Nikolaou, Anastasia; Quiniou, Francoise; Trifuoggi, Marco; Borriello, Ilaria; Vagi, Maria; D'Ambra, Antonello; Pagano, Giovanni.
The aim of the present study was to evaluate marine contamination and toxicity in sediment and pore water from the areas of Izmir Bay (Turkey) and Mytilene Harbor (Greece). The evaluation was performed in terms of selected toxic-metals, polycyclic aromatic compounds (PAR) and toxicity to sea urchin (Paracentrotus lividus) early development and fertilization. Significantly higher levels of metals and total PAR were detected in Izmir vs. Mytilene sediment, and the highest contamination was detected in Izmir Bay innermost sites. Bioassays were carried out in P. lividus embryos and sperm, by evaluating developmental defects and changes in fertilization success by exposing sea urchin embryos or sperm to sediment/seawater suspensions. Whole sediment (WS) showed...

Structure and functions of Polychaetofauna living in Mytilus galloprovincialis assemblages in Thermaikos Gulf (north Aegean Sea) ArchiMer
Damianidis, P; Chintiroglou, Cc.
The purpose of this study is to examine the Polychaetes populations of the mussel Mytilus galloprovincialis Lamarck 1819 assemblage in Thessaloniki Bay (Perea, Neoi Epivates, Agia Triada) in space and time. Forty-eight Polychaetes species, which belong to 16 families, were identified among 10 593 individuals. The different distribution in space and time can be attributed to the life cycles of the Polychaetes, and also to the various biotic interactions. In general, the abundance follows the succession of the seasons, with some deviations though. Thus, the samples can be divided into two major groups, the winter and summer samples. The structure of the feeding guilds of the Polycheates population was also investigated and 9 different feeding guilds were...

The Recruitment of the Endangered Fan Mussel Pinna nobilis (Linnaeus, 1758) on the Ropes of a Mediterranean Mussel Long Line Farm ArchiMer
Theodorou, John A.; James, Ross; Tzovenis, Ioannis; Hellio, Claire.
The fan mussel Pinna nobilis (Linnaeus, 1758) is an endangered bivalve species and is endemic to the Mediterranean Sea. Juvenile animals have been found growing on mussels Mytilus galloprovincialis (Lamarck, 1819) long line aquaculture bounces and ropes within the Maliakos Gulf (Aegean Sea). Animals were sampled from the harvested mussel lines. The results show twelve juvenile P. nobilis per ton of harvested M. galloprovincialis.

Variation in life-history traits of European anchovy along a latitudinal gradient: a bioenergetics modelling approach ArchiMer
Huret, Martin; Tsiaras, K; Daewel, U; Skogen, Md; Gatti, Paul; Petitgas, Pierre; Somarakis, S.
Anchovy Engraulis encrasicolus distribution in European waters spans from the Mediterranean Sea to the North Sea, and is expected to expand further north with global warming. Observations from the eastern Mediterranean (North Aegean Sea), the Bay of Biscay and the North Sea reveal latitudinal differences in growth, maximum size, fecundity and timing of reproduction. We set up a mechanistic framework combining a bioenergetics model with regional physical-biogeochemical models providing temperature and zooplankton biomass to investigate the underlying mechanisms of variation in these traits. The bioenergetics model, based on the Dynamic Energy Budget theory and initially calibrated in the Bay of Biscay, was used to simulate growth and reproduction patterns....

Мультиаберрантные клетки и пикноз ядер у гидробионтов из района с повышенным содержанием естественных радионуклидов IBSS Repository
Цыцугина, В. Г.; Флору, Х.; Поликарпов, Г. Г..
Исследованы аберрации хромосом в клетках гидробионтов на о. Икария в Эгейском море, где вблизи гидро­термальных источников наблюдается повышенное содержание естественных радионуклидов. У ракообраз­ных и червей в этих районах обнаружены наиболее высокий уровень хромосомного мутагенеза, мультиабер-рантные клетки и пикноз ядер. Предполагается, что генотоксические эффекты индуцированы комплексным влиянием низкой величины рН, высокой температуры воды и повышенного содержания естественных ра­дионуклидов.
