concentration of polychlorinated biphenyls and organochlorine pesticides in mullet (mugil cephalus) and sea bass (dicentrarchus labrax) from bizerte lagoon (northern tunisia). | concentrations of polychlorinated biphenyls (pcbs), and organochlorine pesticides (ocps) were determined in two fish species, mullet (mugil cephalus) and sea bass (dicentrarchus labrax), collected from bizerte lagoon and the mediterranean sea. in all samples, pcbs were found in higher concentrations than ocps. the highest concentrations of ocps and pcbs were found in sea bass, and in bizerte lagoon. concentrations of ddts and pcbs detected in this study were generally comparable or slightly high ... | 2013 | 23149188 |
oxidative stress, genotoxicity and histopathology biomarker responses in mullet (mugil cephalus) and sea bass (dicentrarchus labrax) liver from bizerte lagoon (tunisia). | the aim of the study was to evaluate the impact of environmental contaminants on oxidative stress, genotoxic and histopathologic biomarkers in liver of mullet (mugil cephalus) and sea bass (dicentrarchus labrax) collected from a polluted coastal lagoon (bizerte lagoon) in comparison to a reference site (the mediterranean sea). antioxidant enzyme activities were lower in fish from the polluted site compared with fish from the reference site, suggesting deficiency of the antioxidant system to comp ... | 2012 | 22206722 |
polybrominated diphenyl ethers and their methoxylated analogs in mullet (mugil cephalus) and sea bass (dicentrarchus labrax) from bizerte lagoon, tunisia. | concentrations of ten polybrominated diphenyl ethers (pbdes) and eight methoxylated polybrominated diphenyl ethers (meo-pbdes) in mullet (mugil cephalus) and sea bass (dicentrarchus labrax) collected from the bizerte lagoon and the mediterranean sea were investigated. to the best of our knowledge, this is the first report of these compounds in marine fishes from tunisia. the pbde mean concentrations in fish from bizerte lagoon were 45.3 and 96.2 ng g(-1) lw respectively in mullet and sea bass, w ... | 2011 | 21983038 |
morphology of taste buds on the gill arches of the mullet mugil cephalus, and the killifish fundulus heteroclitus. | the morphology of taste buds on the gill arches of two euryhaline teleosts, the mullet mugil cephalus, and the killifish fundulus heteroclitus, were investigated using light microscopic and scanning and transmission electron microscopic techniques. on the mullet gill arches, taste buds were limited to the pharyngeal surfaces of the smooth-surfaced gill rakers. on the killifish gill arches, taste buds were located on the pharyngeal surfaces of all gill rakers and on the gill arch itself at the ba ... | 1983 | 6846207 |
analysis of certain fatty acids and toxic metal bioaccumulation in various tissues of three fish species that are consumed by turkish people. | concentrations of toxic metals (mn, ni, hg, cd, pb, cr) in the muscle, skin, and liver of mugil cephalus, mullus barbatus, and pagellus erythrinus which were purchased in large supermarkets of elazig, and mullus barbatus, which were caught on the sea of iskenderun bay, turkey, were analyzed. fundamental analyses were carried out by inductively coupled plasma-mass spectrometry (icp-ms) after samples were prepared by microwave digestion. mean metal concentrations in different tissues were varied i ... | 2017 | 28236203 |
