چکیده

acute toxicity test on common carp weighing 18 grams and length 12 cm was performed. with concentrations of 0, 2, 5, 10, 20, 40, 60, 80, 100, 200, 400, 600, 800 and 1000 ppm measured at 0, 24, 48 and 96 hours were considered for commercial diesel . processing data using spss software and statistical analysis probit analysis was performed with a confidence level of 95%. the common carp no deaths were observed in the control group and the concentration of 1000 mg, 100% fish mortality was observed. the results show that lc5096h commercial diesel common carp is equal to 697/18 ppm. maximum allowable concentration (mac value) that venom against the 69/718 mg per liter respectively. common carp are not resistant to the adverse effects of commercial diesel fuel tanks with leaks and the entry of these compounds in the marine environment, death and loss of many of these fish.

Changes in biochemical and physiological responses of common carp, Cyprinus carpio L. after long-term exposure to Pb (II)

In this study, the chronic toxic effects of Pb (II) on common carp, Cyprius carpio were  investigated using  several  biomarkers at different levels of biological functions for assessing changes in ecosystem quality. In a bioassay, common carp juveniles were individually exposed to different dose of heavy metal, Pb II (0, 0.45, 0.89, 1.34 mg.l-1) for 28 days. Morphological indices such as hepat...

Effects of dietary exposure to aflatoxins on some plasma biochemical indices of common carp (Cyprinus carpio)

Aflatoxins are a group of secondary fungal metabolites that occur widely in natural contaminants of many feeds under high humidity and temperature, and are potentially dangerous to fish. Therefore, this study was designed to investigate the effects of aflatoxins on some plasma biochemical indices, as clinical biomarkers, in common carp, Cyprinus carpio. Fish were fed diets contaminated with 0 (...

Acute Toxicity and Behavioral Responses of Common Carp Cyprinus carpio (Linn.) To an Organophosphate (Dimethoate)

Dimethoate, a broad spectrum OP insecticide is a potential toxic pollutant, adversely affecting the fauna of aquatic ecosystem. The aim of present study was to assess the acute toxicity of dimethoate on fingerlings of common carp, Cyprinus carpio. The fingerlings were exposed to dimethoate to determine LC values for 24, 48, 72 and 96 h and to study the behavioural alterations. The mortality dat...
