An Assessment of Sediment Quality at the Streams Flowing into Izmir Bay, Aegean Sea, Turkey

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

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...

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...

Phytoplankton growth and microzooplankton grazing in the Homa Lagoon (İzmir Bay, Turkey)

 Phytoplankton growth and microzooplankton grazing were investigated at one station in the Homa Lagoon from February to January in 2006-2007. Our results showed significant seasonal variations in phytoplankton dynamics. Microzooplankton was mainly composed of dinoflagellates and tintinnid ciliates and nauplii. Microzooplankton grazing increased with increasing of temperature. Grazing rate was ma...
