this study reports the incidence of histological alterations in morphometric changes in the liver and ovary of acanthopagrus latus collected from an urban stream impaired by anthropogenic activities and from a clean site (reference). mercury concentration was determined using a standard cold vapor atomic absorption. the results showed that mercury concentration at the creek waters, and speciall...

Being a biologically diversed hotspot in the global marine ecosystem, Beibu Gulf is inhabited by high diversity of fish and serves as vital fishing ground China. Due to continuous overfishing, fishery resource has drastically declined Gulf. However, information about ichthyoplankton assemblages this area still lacking. In present study, diversity, spatial temporal distribution patterns, assembl...

Juvenile black sea bream, Acanthopagrus schlegelii, were exposed to waterborne zinc (Zn) at concentrations of 0, 200, and 400 μg/L, at temperatures of 18 or 26 °C for 4 weeks. Superoxide dismutase (SOD) activities in the liver and gill of A. schlegelii significantly increased following exposure to waterborne Zn. Significant reduction in glutathione S-transferase (GST) activity in the liver and ...

Background: We examined the effects of phenanthrene (Phe) on hematological parameters of yellowfin seabream (Acanthopagrus latus). Methods: The research was carried out in Jan 2016 at Khorramshahr University of Marine Science and Technology, Khorramshahr, Iran. Fish were injected with different concentrations (0, 2, 20 and 40 mg/kg) of Phe and blood, samples were taken from fish 1, 4, 7 and 14...

In this study we detect different levels of blood cells and hematological parameters in five creeks of Mahshahr region in North West of Persian Gulf with different levels of pollutant to characterized hematological response of Yellowfin seabream to environmental pollutant and undesirable materials. Numbers of Blood leukocytes was performed by a hemocytometer Neubauer under the light microscope....

the major sources of pahs are anthropogenic. these may be generated by pyrolytic and petrogenic processes. low molecular weight pahs come into the aquatic system through the accidentally leakage of oil spills. incomplete combustion at high temperature will release high molecular weight pahs by products of pyrolytic processes. the methods for assigning sources of pahs include paired isomeric rat...
