The study shows rainbow trout endure an average of 10 minutes of intense pain during air asphyxia, with estimates ranging from 2 to 22 minutes depending on factors like fish size and water temperature. This translates to approximately 24 minutes of pain per kilogram of fish. These estimates are based on a comprehensive review of existing research to assess the intensity and duration of pain and distress experienced by the fish.

Crucially, the study also assesses the cost-effectiveness of interventions. If implemented properly, electrical stunning could avert 60 to 1,200 minutes of moderate to extreme pain for every U.S. dollar of capital cost.

And to be fair, we don't even care about the death of most humans.
