Metabolic effects of cortisol in the European eel, Anguilla anguilla (L.)

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

“…It would appear that cholesterol levels are insensitive to stress as no effect was found in this study. This is supported by previous work showing no effect of cortisol on cholesterol in the European eel Anguilla anguilla L. (Lidman et al, 1979) or in acutely stressed channel catfish Ictalurus punctatus Rafinesque (Ellsaesser & Clem, 1987).…”

Effects of chronic Cortisol administration and daily acute stress on growth, physiological conditions, and stress responses in juvenile rainbow trout

“…Increased plasma glucose in fish after 2 wk of feeding with cortisol is consistent with findings in previous investigations (Butler 1968, Patent 1970, Inui & Yokote 1975, Lidman et al 1979, Leach & Taylor 1982. In many of these studies, high doses of cortisol were applied by injection, thereby introducing the possibility that hepatic glycogenolysis, stimulated by stressinduced catecholamine secretion (Nakano & Tomlinson 1967, Mazeaud et al 1977, also modified plasma glucose.…”

The hematological response to exhaustive exercise in ‘all-fish’ growth hormone transgenic common carp (Cyprinus carpio L.)

“…In Arctic charr, similar plasma cholesterol concentrations were found between GH transgenics and controls, but the transgenic fish had decreased plasma triglyceride concentrations (Krasnov et al, 1999). Previous studies in carp (Ruane et al, 2001) and other fish species (Lidman et al, 1979;Ellsaesser and Clem, 1987) as well as our current results in control carp show that plasma cholesterol and triglyceride levels are not responsive to acute stress. A very interesting result of the present study was that the plasma cholesterol and triglyceride concentrations in transgenic fish both increased significantly immediately following exercise (0 h) and at 1 h post-exercise, then returned to resting levels by 2 h of recovery.…”
