Plasma cortisol and metabolite level profiles in two isogenic strains of common carp during confinement

摘要: A rapid increase in common carp Cyprinus carpio plasma cortisol levels was noted, two experiments, after 30 mins of a 3 h net confinement, which sustained while the fish were held nets. After release from nets, returned to control values 1 h. Plasma glucose and free fatty acid elevated by confinement. Glucose increased min but basal 22 recovery acids not until confinement remained high for duration period. h, lactate reduced low further No change either triglyceride or cholesterol found during study. Confinement had no effect on haematocrit blood haemoglobin reduced. In both experiments hypochloraemia occurred response However, pre-confinement These results show that rearing isogenic strains, under identical conditions, reproducable an acute stressor these respond similar manner other teleost species.
