  11. The possible identification and introduction of metallothionein in Persian Sturgeon (Acipenser persicus)

    Shariati Feizabadi, Fatemeh
    Due to anthropogenic activities, toxic metals still represent a threat for various marine organisms. Metallothionein (MT) and cadmium concentration in gills, liver, and kidney tissues and cadmium partitioning in soluble (cytosol) and insoluble fractions of mentioned tissues of Persian sturgeon (Acipenser persicus) were determined following exposure to sub-lethal levels of waterborne cadmium (Cd) (50, 400 and 1000 μg L-1) after 1, 2, 4 and 14 days. The increases of MT from background levels in comparison to controls were 4.6-, 3-, and 2.8-fold for kidney, liver, and gills, respectively after 14 days. The matallothionein concentration in liver was in the range...

  15. Survey of Amphiprion clarki & Amphiprion sebae populations in Persian Gulf by molecular genetics

    Hazaie, Kaivan
    Anemone fishes are a group of 28 species of coral reef fishes belonging to the family Pomacentridae, subfamily Amphiprioninae and all have an obligate symbiotic relationship with sea anemones. Two species of these small ornamental fishes have been identified in the Persian Gulf including Amphiprion clarkii and A. sebae. The phylogenetic relationship between Amphiprion species of the Persian Gulf was studied by collecting 15 samples from three Iranian islands, Larak, Farur and Kish. DNA was extracted from each sample and a part of mtDNA was amplified. Two pairs of primers were designed to amplify a final target of 400 by...

  16. Assessment of seawater pollution by heavy metals (lead & cadmium) in the Qeshm rocky shore: use of the sea urchin, Echinometra mathaei, as a bioindicator
