Fish muscle tissue was separated after biometry. The tissue was disgusted and analyzed using Atomic Absorption Spectrometry (AAS). The results showed that there was significant positive correlation between the concentration of lead and fish size (p<0.05). We found a significant difference between the concentration of lead in different stations (p<0.05). In both summer and winter, accumulation of lead in the muscle of Mudskipper waltoni was higher than other sampling areas. However, the lead level in the fish tissue was lower than global standards (FAO/WHO 2.14 μg/g).

Sampling was performed in four seasons (spring, summer, autumn and winter) and in eight transects perpendicular to the coast. 384 phytoplankton and 160 zooplankton samples were collected over five different water depths (5, 10, 20, 50 and 100 meters). Multivariate statistical analysis (PCA, CCA and SMRA) showed that high abundance of filamented species of Cyanophyta (Oscillatoria sp.), chain form (Dactyliosolen fragilissima) and large size (Pseudosolenia calcar-avis) of Bacillariophyta had the main role in zooplznkton feeding pattern, particularly in summer and winter. Small size phytoplankton (Cyclotella meneghiniana, Exuviaella cordata) and relatively short filament (Binuclearia lauterbornii) were occasionally eaten by zooplankton. Feeding habits of zooplankton species were not the same in different seasons and was strongly depended on the phytoplankton structure (species diversity and abundance). Low species diversity and abundance of zooplankton which accompanied with high species diversity and abundance of phytoplankton were the main reasons that limited top-down control of zooplankton on phytoplankton abundance reduction through grazing.}, Keywords = {Zooplankton, Phytoplankton, Feeding, Caspian Sea.}, volume = {4}, Number = {15}, pages = {29-38}, publisher = {Iranian National Institute for Oceanography and Atmospheric Science}, url = {http://joc.inio.ac.ir/article-1-417-en.html}, eprint = {http://joc.inio.ac.ir/article-1-417-en.pdf}, journal = {Journal of Oceanography}, issn = {1562-1057}, eissn = {2476-6755}, year = {2013} } @article{ author = {Azimi, Ali and Safahieh, Alireza and DadolahiSohrab, Ali}, title = {Comparison of Mercury and Cadmium Bioaccumulation in Oyster Crassostrea sp.

Results showed that tPAHs concentrations in seawater and sediment were significantly different among the studied stations (P<0.05). The maximum tPAHs concentration was measured in the seawater and sediment collected from Rafael while the minimum values were observed in the Abshirinkon station. The Concentration of anthracene, phenanthrene, fluoranthene and pyrene in seawater was appeared above the standard rate mentioned by Canadian environmental quality guidelines. Different patterns of tPAHs composition were observed in water and sediment among the studied stations. Based on the number of the rings in the molecules, 3 rings PAHs were dominant in the seawater, while in the sediment, 5 and 6 rings PAHs appeared in the higher concentrations.
