               Abstract
In the present study, The effect of phthalate ester toxicity (0.1 and 1 mg/L) was investigated on some non-specific mucus parameters of common carp (Cyprinus carpio). 180 common carp (17.60±2.22gr) is gathered from warm water fish center and they were allocated into 9 tanks (20 Fish per tank). Fish adapted to new condition for a week. During this time; they were feed twice a day with same diets. Fishes were exposed at 3 concentration treatments containing 0; 0.1 and 1 mg/L DEHP under laboratory condition (25±0.5°C; pH: 7.4-8) for a period of 96 hours. Alkaline phosphatase, lysozyme, soluble protein, and immunoglobulin of mucus was measured and evaluated. The results showed that the levels of lysozyme, alkaline phosphatase and immunoglobulin in common carp skin mucus decreased when exposed to DEHP (with increasing concentration and exposure duration) And the level of soluble protein of common carp skin mucus increased when exposed to DEHP (with increasing concentration and exposure duration). These results indicated that concentrations of DEHP beneficially affects Amino Acid profiles of skin mucus in carp and they were categorized in 4 branches. There were Significant differences between exposed and control groups. Therefore; fish skin mucus can be a biomarker for showing contaminants and toxins. And the high consumption of plastic materials can be a warning to the health of aquatic animals and humans.
