Serum cortisol, glucose and lipids in plaice (Pleuronectes platessa L.) exposed to starvation and aquarium stress

Mebendazole dietary supplementation controls Monogenoidea (Platyhelminthes: Dactylogyridae) and does not alter the physiology of the freshwater fish Colossoma macropomum (Cuvier, 1818)

“…Glucose is one of the most used stress indicator besides other parameters (White and Fletcher, 1986). In this study, glucose levels (41-49 mg·L −1 ) do not characterize a stressful condition being close to normal values found in cage-reared C. macropomum (Chagas et al, 2003).…”

Short fasting and refeeding in red porgy (Pagrus pagrus, Linnaeus 1758): Response of some haematological, biochemical and non specific immune parameters

“…In contrast, the evidences in fish are contradictory and starvation results in both reduction, increase or no change in cortisol levels (Pottinger et al, 2003). However, it is difficult to draw conclusions because while some researches are in agreement with these results, reporting reduced or increased circulating cortisol levels during fasting in fish (Sheridan and Mommsen, 1991;Farbridge and Leatherland, 1992;Blom et al, 2000;Kelley et al, 2001;Jørgensen et al, 2002;Caruso et al, 2010), others are in conflict (White and Fletcher, 1986;Sumpter et al, 1991;Vijayan et al, 1993;Holloway et al, 1994;Jørgensen et al, 1999;Pottinger et al, 2003;Caruso et al, 2011).…”

Immunological assessment of hybrid striped bass at three culture temperatures

“…This study suggests that it might also be used to investigate the optimal temperature requirements for a species. Stress-related increases in corticosteroids have been extensively studied in fish (Ainsworth et al, 1985;White & Fletcher, 1986;Laidley & Leatherland, 1988), and elevated levels have been shown to result in a decreased immune capability (Pickering, 1984;Ellsaesser & Clem, 1986) and an increase in disease susceptibility (Wechsler et al, 1986;Wiik et al, 1989;Houghton & Matthews, 1990). In this study, serum cortisol values were further examined by using factorial ANOVA and trend analysis, but no consistent pattern of elevation was evident.…”
