The crustacean fauna associated with Mytilus galloprovincialis and Mytilaster minimus (Mollusca, Bivalvia) beds from Izmir Bay was investigated spatially in autumn 2014. Samples were collected by means of a quadrate sampler covering 400 cm2 at four intertidal stations from the inner (3 stations) and outer (a single station) parts of the bay. A total of 831 individuals belonging to 16 species of crustaceans, were collected and identified. Among these, the isopod Paradella dianae was the most dominant species represented with 227 individuals. Paradella dianae and the amphipod Hyale crassipes were the most frequent crustacean species on the mussel beds with 58.33% occurrence. The maximum crustacean biomass (306.29 g/m2) was calculated at station 4. The amphipods Stenothoe gallensis and Elasmopus pectenicrus, and the isopod P. dianae were the alien crustaceans encountered in the present study.

The sea has involved a large variety of environmental contaminants and plays a crucial role in aquatic ecosystems. The Izmir Bay, which has been rapidly polluted since the 1960s, was one of the intensely polluted areas in the Mediterranean. Organic materials, hydrocarbons, metals, and pathogenic organisms that are accumulated in the region, caused high pollution and threaten health and aesthetics. Because of this, the aim of this paper was focus on to investigations of the genetic damages in mussels in Izmir Bay. Investigations of mutagenic/carcinogenic potential have an advantage in genotoxicity studies because biomarker for pollution exposure in mussel is the early detection of possible long-term effects such as cancer. Therefore, genotoxicity was the focus of the biomarker investigations in mussel during the investigations. Thus, micronucleus tests were afforded to determine genetic damage in the haemolymph, liver, and gills of Mytilus galloprovincialis living in Izmir Bay (Western Coast of Turkey). In the present study, results showed that the frequency of MN was found at a high level in station 4 and station 5 where wastes from dockyard existed contributed to the high level of pollution. The recommendation is to standardize procedures for assessment of the toxic impact of pollutants at the cellular level in aquatic species by using micronucleus assays for biomonitoring of environmental pollution.

A total of ten specimens of Pseudonereis anomala (Polychaeta: Nereididae) were collected on the shallow water hard substratum (0·2 m) at four stations located in the inner part of Izmir Bay (Aegean Sea, eastern Mediterranean) in January 2004. The absence of this species among the material collected previously at the same stations might suggest that it has recently become established in the area. A re-description of the species together with its ecological, reproductive, feeding and distributional aspects are provided.

Ecological Characteristics

This paper deals with the sipunculan species distributed in Izmir Bay (Aegean Sea, eastern Mediterranean). Benthic samples were taken at 29 stations between 1998 and 2001 at depths ranging from 8 to 77 m. Six species and 200 individuals belonging to three families were found. Aspidosiphon (A.) mexicanus is newly recorded from Izmir Bay. The majority of specimens were found on a sandy-mud substratum (42%), followed by sand (35%), muddy-sand (19%) and sand (3%), respectively. Among the habitats, Posidonia oceanica and muddy-sand were represented by the highest numbers of species (4 species), followed by sandy-mud (3 species), and sand (2 species). The densities of the species at sampling stations were determined and compared seasonally, based on the data collected in 2001. Brief descriptions of the species and their distributional, reproductive and ecological characteristics are given.
