The aim of this study was to determine the effects of chronic waterborne copper (Cu)
exposure on the acute stress-induced cortisol response and associated physiological …

Fish are exposed to multiple stressors, often acting concurrently, in their environment. To
evaluate the potential of Cu to act as a chemical stressor, rainbow trout (Oncorhynchus …

The effects of increased endogenous cortisol levels were compared with those of sublethal
copper exposurein the freshwater common carp, Cyprinus carpio. Fish were exposed to …

This study compared the effects of increased endogenous cortisol levels and/or sublethal Cu
exposure on Cu accumulation and stress protein levels (HSP70) in the freshwater common …

Copper is an essential element needed for many physiological processes. But at high
concentrations copper is toxic, so homeostatic mechanisms are required to regulate internal …

Background. Copper is a heavy metal, and an aquatic pollutant, known for its bio-
accumulative and non-biodegradable properties. In the aquatic ecosystems, acute and …

Plasma cortisol concentrations in juvenile channel catfish Ictalurus punctatus exposed to 1.7
mg copper sulfate/L for 24 h in a simulated therapeutic treatment episode rose to a level …

We evaluated effects of sublethal copper exposure in 3 different freshwater fish: rainbow
trout (Oncorhynchus mykiss), common carp (Cyprinus carpio) and gibel carp (Carassius …

Plasma ions and cortisol levels were studied in immature tilapia for 6 days to a range of
sublethal concentrations of Cu (50, 100 and 200 μg Cu l− 1), Cd (20, 35 and 70 μg Cd l− 1) …

In order to evaluate the effects of copper and atrazine on the stress response of the
freshwater fish Prochilodus lineatus, juvenile fish were pre-exposed to copper (20μgL− 1) or …
