In the rusty crayfish (Orconectes rusticus), toxicity of copper at high concentrations is due to the coagulatory action on cellular proteins and to interference with respiratory processes at low concentrations, copper causes degenerative changes in certain tissues and interferes with glutathione equilibrium (Hubschman 1967). Larvae of the red crayfish (Procambarus clarkii) exposed to copper as embryos are less sensitive than those exposed after hatching, suggesting acclimatization (Rice and Harrison 1983).
