Differential effects of exposure to parasites and bacteria on stress response in turbot Scophthalmus maximus simultaneously stressed by low water depth
The stress response of turbot Scophthalmus maximus was evaluated in fish maintained 8 days under different water depths, normal ( NWD , 30 cm depth, total water volume 40 l) or low ( LWD , 5 cm depth, total water volume 10 l), in the additional presence of infection–infestation of two pathogens of t...

The stress response of turbot Scophthalmus maximus was evaluated in fish maintained 8 days under different water depths, normal ( NWD , 30 cm depth, total water volume 40 l) or low ( LWD , 5 cm depth, total water volume 10 l), in the additional presence of infection–infestation of two pathogens of this species. This was caused by intraperitoneal injection of sublethal doses of the bacterium Aeromonas salmonicida subsp. salmonicida or the parasite Philasterides dicentrarchi (Ciliophora:Scuticociliatida). The LWD conditions were stressful for fish, causing increased levels of cortisol in plasma, decreased levels of glycogen in liver and nicotinamide adenine dinucleotide phosphate ( NADP ) and increased activities of G6Pase and GSase . The presence of bacteria or parasites in fish under NWD resulted in increased cortisol levels in plasma whereas in liver, changes were of minor importance including decreased levels of lactate and GSase activity. The simultaneous presence of bacteria and parasites in fish under NWD resulted a sharp increase in the levels of cortisol in plasma and decreased levels of glucose.
