In this study, concentrations of mercury (Hg) and 16 other elements as well as methylmercury speciation were quantified in muscle and liver of two commercial fish species. It was also our intention to evaluate potential risks to human health associated with seafood consumption. The fish species, Mullet and Kutum (Caspian White fish) fishes, were obtained from Tonekabon at the Iranian waters of ...

anzali wetland is one of the most important aquatic ecosystems of iran located at southwest of the caspian sea. this wetland is a habitat for valuable fish with vital role in life cycle of this ecosystem. assessment of pollutants concentration is rational due to complications of determining biological effects in a habitat. the present study examined the concentration of lead (pb) and cadmium (c...

The aim of this study was to investigate the effective concentration of ethanolic extract  of bee pollen on liver, spleen and heart tissues of fish. Bee pollen extract in various concentrations (0.5, 2.5, 5, 10, 20 and 30 ppm) was administered to fish for 96 h under aquarium conditions. The malondialdehyde (MDA) levels, total antioxidant status (TAS), total oxidant status (TOS), oxidative stres...

background: musa creek, suitable place for spawning of many fish species and other organisms, is one of the most important and voluble ecosystems in the west of iran that received so many attentions due to existents of various industries around this part of persian gulf. previous studies confirmed that marine fish have collected high amounts of pollutants in this area which could be lead to sev...

In the current study the plasma metabolites of silvery-black porgy (Sparidentex hasta) juveniles fed with different lipids sources were analyzed in order to bio-monitoring fish health condition. In this regard, an eight-week feeding trial was conducted using seven isonitrogenous (50%) and isolipidic (20%) experimental diets : FO, CO (canola oil), SO (sunflower oil), T (tallow), FC (fish oil + c...

determination of metal levels in muscle, liver and gill of common carp ( cyprinus carpio ) species caught from shirinsu wetland was done using icp-oes. the mean level of cu, pb and zn in muscle, liver and gill of fish were 0.01±0.002, 0.015±0.003, 0.007±0.001; 0.13±0.005, 0.006±0.001, 0.62±0.11 and 0.26±0.008, 0.009±0.002, 0.53±0.10 μg g −1 , respectively. metal levels in muscle were generally ...

the heavy metals concentrations including zinc, copper, lead and cadmium (zn, cu, pb and cd) in water and sediments in gorgan bay and their accumulation in rutilus frisii kutum, acipenser persicus, rutilus rutilus caspicus and cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. there was substantial increase in concentration of heavy metals ingoing from the water to the ...

The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish o...
