Copper-Induced Chemosensory Impairment is Reversed by a Short Depuration Period in Northern Clearwater Crayfish (Faxonius propinquus)

Crayfish rely on their chemosensory system for many essential behaviours including finding food, finding mates, and to recognize individuals. Copper can impair chemosensation in crayfish at low concentrations; however, it is not clear if the effect is ameliorated once copper is removed. To better understand the effect of and recovery from copper exposure in crayfish, we exposed Northern clearwater crayfish (Faxonius propinquus) to 31.3 $${\upmu …
