Efficacy of Carbonic Acid as an Anesthetic for Rainbow Trout
We determined effective concentration ranges for carbonic acid as an anesthetic for rainbow trout Oncorhynchus mykiss across a wide range of water temperatures and alkalinities. Effective concentrations were based on criteria for induction time (
