Lessepsian Fishes of Izmir Bay (Aegean Sea)

Nutrient Fluxes and Their Dynamics in the Inner Izmir Bay Sediments (Eastern Aegean Sea)

Growth and feeding habits of the brown comber, Serranus hepatus (Linnaeus, 1758) in Izmir Bay, Aegean Sea

Age, growth and diet of brown comber, Serranus hepatus, were determined from specimens collected in Izmir Bay, Aegean Sea. Total length ranged from 5.20 to 11.70 cm, while weight varied between 1.89 and 24.97 g. The length-weight relationship was W=0.0157*L2.998. Age was determined by otolith readings, where a maximum age of 4 years was observed. The von Bertalanffy growth parameters were estim...

Mercury Accumulation and Speciation in Red Mullet (mullus Barbatus) and Annular Sea Bream (diplodus Annularis) from Izmir Bay (eastern Aegean)

Total mercury (THg) and methylmercury (MeHg) concentrations were investigated in two different species from the Izmir Bay. The levels of THg and MeHg in fish tissue, ranging from 4.4 to 221.4 μg THg kg and 3.8-194.8 μg MeHg kg (wet wt.), varied according to sampling point and season. The results indicate that none of the fish analysed was ≥ 0.500 μg g for THg and ≥ 0.300 μg g for MeHg and nor d...

Evaluations of heavy metal pollution in sediment and Mullus barbatus from the Izmir Bay (Eastern Aegean) during 1997-2009.

Izmir Bay is one of the great natural bays of the Mediterranean. The surface sediment and fish samples were collected during 1997-2009. The sediment concentrations of inner bay showed significant enrichments during sampling periods. Outer and middle bays exhibited low levels of metal enrichments except the estuary of Gediz River. The concentrations were generally higher than the background leve...

Source of Aegean Sea harbour porpoises

Documented sightings of harbour porpoises in the Mediterranean are rare, although the species is common in the neighbouring North Atlantic and Black Sea. However, in the past 2 decades, 4 harbour porpoises Phocoena phocoena have been recorded in the northern Aegean Sea in the eastern Mediterranean Basin. Samples were taken from 2 of these. Both have a genetic signature indicative of the Black S...
