A study was conducted to evaluate the uptake and accumulation of waterborne lead (Pb) in various tissues of Catla catla when exposed to lower doses. Single breed fingerlings (6-8 cm) of C. catla were obtained from a commercial fish seed hatchery. Six groups (in duplicate) of fish (40 each) were maintained at 22 C, pH 7.0, hardness 140 mg/l and DO 7.0 mg/l in 90 liters of water in glass tanks. E...
Background and Aim: The objective of this study was to determine the contents of heavy metals Hg, Cd and Pb in the muscle, liver and gill tissues of Liza abu fish in the Dez and Bahmanshir Rivers in Khoozestan Province, Iran in winter 2010. Materials and Methods: The study included 108 samples of Liza abu tissues. The metals were extracted from the tissues using the wet-digestion method and t...
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...
This study was undertaken to determine the concentration of Pb in liver and muscle tissues of Platycephalus indicus fish collected from two creeks Jafari and Behad (Musa estuary, northwestern Persian Gulf) and was conducted to survey influence of total length and sex on accumulation of Pb in fish tissues during Agust 2010. Concentration of Pb in sediments was also measured. Total number of fish...

To assess whether vertebrates can acquire, from their diet, ultraviolet radiation-absorbing mycosporine-like amino acids (MAAs), medaka fish and hairless mice were maintained for 150 and 130 days, respectively, on diets either including Mastocarpus stellatus (rich in MAAs) or the same diets without this red alga. In medaka, the MAAs palythine and asterina-330, present in trace quantities in the...
the study monitored the toxicity of environmentally relevant concentration of pesticides and metals in zebra fish danio rerio. zebra fish were exposed to environmentally relevant concentration of pesticides and metals for a period of 14 days. the individual and the combined toxicity of pesticides and metals were evaluated. the pesticides and metals treated groups showed histopathological altera...
In this research, concentrations of heavy metals (i.e., cadmium, lead, copper) in muscle, liver and gill tissues of Euryglossa orientalis (Family: Soleidae) in two fishing areas, from northern Persian Gulf that names Hendijan port (Bahrekan) in Khuzestan province and Deylam port in Bushehr province were measured and compared. Fifty fish samples randomly were collected from Hendijan and Deylam p...
in this study, three stations of the north persian gulf were analyzed in order to determinethe effect of trophic levels on the concentration of harmful pahs in fish and sediment. in all cases,similar distributions were observed in which benzo(a)pyrene largely predominated andbenzo(b)fluoranthene and pyrene were the second major compounds in fish tissues. the predominantcomponents of pahs in sed...
