|Abstract||There is considerable pressure for Animal Care and Ethics Councils to recommend using analgesics in experiments that involve fish. Although we do have some data regarding this issue, I argue that we do not know enough to recommend any being used. For example, the doses of morphine used in fish experi- ments range from 10 to 3000 mg/kg relative to doses used in mammals that typically range from 2 to 5 mg/ kg. I recommend that we continue to use anaesthet- ics that are commonly used with fish (tricaine, benzo- caine, and eugenol) because these also probably act as analgesics in fish as they do in mammals, and thus, may have some analgesic properties post-operatively. There are no adequate tests that would allow us to recommend using analgesics for farmed fish that may be consumed by humans or pets.|
