To evaluate the levels of cortisol, glucose and other possible indicators of goldfish ,Carassius auratus, in response to stress, in the first experiment, Bisphenol A (0.5 mg/L), Naphthalene (200 μg/L) and Butachlor (60%) (0.28 µg/L) were added to the aquariums water for two weeks.

To evaluate the levels of cortisol, glucose and other possible indicators of goldfish ,Carassius auratus, in response to stress, in the first experiment, Bisphenol A (0.5 mg/L), Naphthalene (200 μg/L) and Butachlor (60%) (0.28 µg/L) were added to the aquariums water for two weeks. In the second experiment, intra-peritoneal injections of Bisphenol A, Naphthalene and Butachlor,with dose 50 mg/kg, 50 mg/kg, 20 μL on the body weight of fish were performed. On the fifth day and the end of the experiment (fifteenth day) as well as 48 hours after injection, blood sampling from caudal vein was taken and levels of cortisol, glucose, total protein and blood plasma were measured inorganic phosphorous. The results showed that the cortisol and glucose levels on day 5, there was a significant difference between control and Butachlor treatments (P 0.05). Comparing the results of the analysis of blood plasma in the fifth and fifteenth days of experiment, it was found that levels of cortisol and glucose in the treatment Butachlor had significantly different together within two periods (P

Abstract In this study, the effect of stocking density on some hematological (Red and white blood cells) and serum biochemical parameters (Glucose, triglycerides, cholesterol, total protein, inorganic phosphorus, calcium and magnesium, enzymes alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase and cortisol) of Carassius auratus was investigated. Fish with average weight 200±18 g were stocked randomly into 6 tank with triplicate in two treatments for a 30-day period and were submitted to different stocking densities: low density (T1, 10 kg/m3) and high density (T2, 45 kg/m3). At the end of the trial, Fish from each group were selected and their blood was collected and the following parameters were analyzed. Fish held at high density showed significant higher levels of cortisol, glucose and alkaline phosphatase (23±0.4 ng/dl, 52±3.2 mg/dl and 93.2±8.1U/L, respectively) compared with those held at low density (36±0.9 ng/dl, 83±5.2 mg/dl and 61.2±6.3U/L, respectively), while the levels of triglycerides significantly decreased with increasing density (PP
