Abstract

In Brazil, Hyphessobrycon callistus is an important commercially exploited species and it is an ideal animal for studying
damages caused by the effects of heavy metal that are often detected in the aquatic environment. The main purpose of the
present study was to detect the acute toxicity of Cd to H. callistus and investigate its effects on oxygen consumption, ammonium
excretion, and the neutral red retention time assay to estimate effects at the cellular level. Such investigations have
not been carried out before with this species. Acute toxicity of Cd to H. callistus in 24h, 48h, 72h, and 96h medium lethal
concentration (LC50) was showed to be 45.95, 32.49, 28.28, and 15.16 mg/l, respectively. Furthermore, it was found that
exposure of fish to 1.5 mg/l Cd caused reduction in oxygen consumption and ammonium excretion of 59% and 71.5%,
respectively as compared to controls.
