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) …

Exposure of freshwater tilapia to a sublethal cadmium concentration in the water (10 μg Cd/l)
induced a rapid elevation (within 1 h) of plasma cortisol levels. Concentrations remained …

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 …

Juvenile tilapia (Oreochromis mossambicus) were exposed for 96 h to ranges of sublethal
concentrations of Cu or Cd, under both fed and non-fed conditions. Exposure to one metal …

1. Freshwater cichlids Oreochromis mossambicus (tilapia) were exposed to 10 μg Cd/l in
ambient water for 2, 4, 14 and 35 days. Plasma cortisol and glucose levels were determined …

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 …

In juvenile tilapia the effects of waterborne Cu, Cd, and combinations of these metals on
whole‐body Ca fluxes were studied, using 45Ca as tracer. The maintenance of Ca …

The cadmium impact on interrenal and thyroid functions was assessed in tilapia,
Oreochromis niloticus. Fish were exposed to 25 mg L− 1 of CdCl 2 during 24, 48, and 96 h …

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