Stomach contents of six striped dolphins taken as by-catch in the swordfish fishery in the eastern Mediterranean Sea off the Turkish coast were examined. In total, 29 taxa were identified to species or family and 1777 individual food items (1394 bony fishes, 289 cephalopods, 94 crustaceans) were counted.Diaphusspp. andCeratoscopelus maderensiswere the most remarkable ones, as they accounted for 70.45% of the total number of fishes.Onychoteuthis banksii, on the other hand, was the only cephalopod species found in all stomach content analyses and represented 38.06% of the total number of cephalopods. Bony fish species:Myctophum punctatum, Notoscopelus elongatus, Electrona risso, Sudis hyalina,Moridae sp., Phycidae sp., Sternoptychidae sp. and cephalopods:Pterygioteuthis giardiandChtenopteryx siculawere reported the first time in the stomach contents of striped dolphin in the Mediterranean Sea.

The stomachsof 23 striped dolphins (Stenella coeruleoalba Meyen, 1833, Cetacea), stranded along the Ligurian coast (western Mediterranean Sea), contained 32 species of cephalopods, crustaceans and fishes, totalling an estimated 2,723 prey specimens representing about 36 kg in weight. Cephalopods and bony fishes were equally important in the diet (50%). Todarodes sagittatus (34.5%) and Micromesistius poutassou (25.9%) were found to be the most important food species. Other species belonging to six cephalopod families, three crustacean families and nine bony fish families, contributed to the diet with variable numbers, weights, and occurrences, demonstrating the opportunistic character of striped dolphin feeding.

The tropical Atlantic originated saddled snake eel, Pisodonophis semicinctus (Richardson, 1848) and the Indian Ocean originated striped piggy, Pomadasys stridens (Forsskål, 1775), are being recorded for the first time from Turkish coasts. First species is also a new addition to the eastern Mediterranean ichthyofauna, while the latter species has expanded its range to the northeastern Levant Sea.

Sampling studies in the Turkish Aegean Sea revealed the occurrence of the sea spider species, Trygaeus communis Dohrn, 1881. The genus Trygaeus and species Trygaeus communis Dohrn, 1881 are recorded for the first time from Turkey. The genus and species are also recorded for the second time from the Eastern Mediterranean Sea. Distribution map of the species in the Eastern Mediterranean Sea is provided, together with photographs and line drawing of the species. This record further extends the known distribution of the species to Turkey in the Eastern Mediterranean.

Thunnus Alalunga

In this study, the stomach contents of 116 albacore specimens, Thunnus alalunga were examined from the eastern Mediterranean Sea. Fifty-five of the 116 stomachs examined were empty. The occurrence of major prey categories in stomachs were 95.1% cephalopods, 47.5% teleosts and 39.3% crustaceans with a total of 633 individuals belonging to 14 species identified. Heteroteuthis dispar from the order Sepiolida constituted 56.40% of the main cephalopod prey followed by Onychoteuthis banksii from the order Teuthida.

AbstractDuring benthic surveys in the northern Aegean Sea, 188 amphipod species were found; 39 among these comprise new records for the amphipod fauna of the eastern Mediterranean Sea, 41 are reported for the first time from the Aegean Sea and 62 are new for the fauna of the northern Aegean Sea. A checklist of the amphipods known from the Aegean Sea up to the present is given (239 species), along with their distribution in certain Mediterranean areas. For the most interesting species found, information on their distribution and their habitat is given. The amphipod fauna of the above areas is estimated, on the basis of the relevant literature. Finally, the affinities among these areas using the coefficient of Czekanowski, along with the number of species common to each pair of areas, are estimated.

Abstract. Shelled pteropods represent an excellent sentinel for indicating exposure to ocean acidification (OA). Here, for the first time, we characterise spring pteropod distribution throughout the Mediterranean Sea, a region that has been identified as a climate change hot-spot. The presence of a west–east natural biogeochemical gradient makes this region a natural laboratory to investigate how the variability in environmental parameters may affect pteropod distribution. Results show that pteropod abundance is significantly higher in the eastern Mediterranean Sea where there is a higher aragonite saturation state (Ωar), showing that distribution is positively correlated with Ωar. We also observed a resilience of pteropods to higher temperatures and low nutrient conditions, including phosphorous limitation. The higher abundance of pteropods in ultra-oligotrophic conditions (eastern Mediterranean Sea) suggests that this organism can play an important role as the prime calcifying zooplankton within specific oligotrophic regions.
