Physiological responses of the red rocky crab Cancer antennarius exposed to different concentrations of copper sulfate
In this study we evaluated physiological, metabolic and hematological responses for the crab Cancer antennarius to different copper sulfate concentrations (0.5, 1.0, 1.5, 2.0 mg L-1). The evaluated responses were: the median lethal dose, osmoregulatory capacity, oxygen consumption, ammonium excretio...

The median lethal dose (LD50) we found was 1.6 mg L-1 of copper sulfate.
