Acute Toxicity and Behavioral Changes of the Gold Fish (Carassius Auratus) Exposed to Malathion and Hinosan
Background: Pesticides are widely used in agriculture. Excessive use of pesticides has health risk for human and threatens non-target organisms. This research aimed to determine lethal concentrations of malathion and Hinosan for Carassius auratus (5±1 gr) [mean ± SD]. Methods: Experiments were performed according to O.E.C.D for 4 days (96 h) and concentrations of 0, 1, 2, 4, 8 mg L-1 Hinosan...

full textdetection of acute toxicity test (lc50) pesticide chlopyrifos in gold fish (carassius auratus) and comparison its toxicity with other organophosphate toxicity
chlorpyrifos is one of the organophosphate pesticides that are commonly used to control insects in domestic activities and many agricultural farms that are located in close to water sources. hence, the present study, investigate the lethal toxicity of this pesticide. in this study, fish were treated in groups of 21 with different concentrations of chlorpyrifos (aria brand with active ingredient...
full textEffect of Trichlorfon on Hepatic Lipid Accumulation in Crucian Carp Carassius auratus gibelio
This study evaluated the toxic effects of the organophosphate pesticide trichlorfon on hepatic lipid accumulation in crucian carp Carassius auratus gibelio. Seventy-five fish were divided into five groups (each group in triplicate), and then exposed to 0, 0.5, 1.0, 2.0, and 4.0 mg/L of trichlorfon and fed with commercial feed for 30 d. At the end of the experiment, plasma and hepatic lipid meta...
full textThe effects of dietary astaxanthin on the physiological, growth and survival of gold fish larvae (Carassius auratus)
The present research which aimed at identifying the effects of astaxanthin pigment in upgrading efficiency in producing goldfish larvae through 4 treatments and 3 replications was conducted in the winter of 2014. For this reason, a sum of 12,4m3fiber glass fish ponds were prepared where in each, 50 female goldfish breeders were introduced with an average body weight of 47.21±2.19g. Then, 4 diet...
full textInhibition of CYP450 1A and 3A by berberine in crucian carp Carassius auratus gibelio.
Berberine has long been considered as an antibiotic candidate in aquaculture. However, studies regarding its effects on drug-metabolizing enzymes in fish are still limited. In the present study, the effects of berberine on cytochrome P4501A (CYP1A) and CYP3A in crucian carp were investigated. Injection of different concentrations of berberine (0, 5, 25, 50, and 100mg/kg) inhibited the CYP1A mRN...
