Hyperactivity as a Lethal Factor in Fish

Abstract

Death occurs in fishes under certain circumstances following severe muscular activity. The precise cause of death is not yet known. However, it is possible that the severe disturbance to acid-base relationships following the large increase of lactic acid liberated from muscle glycogen may be the principal cause of death. Hyperactivity as a lethal factor in fishes is important in the study of biology of fishes and fisheries management.
