Effects of 2-phenoxyethanol (2-PE) anesthesia on some haematological and biochemical indices of silver carp (Hypophthalmichthys molitrix)

چکیده مقاله:
In this study, the anesthetic effects of 2-phenoxyethanol (2-PE) on possible primary (cortisol level) and secondary (haematological indices and glucose level) stress responses were studied in silver carp (Hypophthalmichthys molitrix). Fish were first exposed to 0.1, 0.3, 0.5, 0.7 and 0.9 mL L-1 2-PE, and the time of induction (deep anesthesia) and recovery were measured. At concentrations of 0.5, 0.7 and 0.9 mL L-1 2-PE, all fish were anaesthetized within 3 min of exposure. For assessing possible stress effects caused by effective concentrations of 2-PE, the haematological indices, serum cortisol and glucose were determined in the deeply anaesthetized fish as stress indicators. 2-PE exposure resulted in a significant increase in red blood cell (RBC) amounts at 0.1 and 0.3 mL L-1. A parallel increase in hemoglobin and Haematocrite amounts at 0.1 concentrations (p<0.05) was observed. The serum cortisol levels had the highest amount in 0.1 mL L-1 of 2-PE. Moreover 2-PE exposure resulted in a significant increase in glucose amounts first at the 0.1 and later in the 0.3 mL L-1 concentrations. This study shows that rapid induction of deep anesthesia with a relatively high concentration of 2-PE (0.5, 0.7 and 0.9 mL L-1) was associated with the lowest effects on the haematological and serum biochemical indices in silver carp and so 0.7 mL L-1 could be suggested as a suitable dose for haematological studies in this species.

متن کاملAspects of Embryonic and Larval Development in Bighead Carp Hypophthalmichthys nobilis and Silver Carp Hypophthalmichthys molitrix
As bighead carp Hypophthalmichthysnobilis and silver carp H. molitrix (the bigheaded carps) are poised to enter the Laurentian Great Lakes and potentially damage the region's economically important fishery, information on developmental rates and behaviors of carps is critical to assessing their ability to establish sustainable populations within the Great Lakes basin. In laboratory experiments,...
متن کاملEvaluation of the Effects of Exposure to Copper Sulfate on some Eco-physiological Parameters in Silver Carp (Hypophthalmichthys molitrix)
Background: Copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. Fish blood is susceptible to contaminationinduced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. Methods: In this study, juvenile species of silver carp with average weight of 200gr we...

Effects of frying by different frying oils on fatty acid profile of silver carp (Hypophthalmichthys molitrix)
The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p<0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunflow...
