The EA-1000B Electrosedation System offers the operator the chance to select just the right settings to achieve the desired outcome in a safe, humane, and non-injurious way. Fish are rendered unconscious almost immediately as the specially modified electric current passes through the water in a custom-designed tank. The depth of sedation can be light (lasting less than a minute) or deep (several minutes) depending on the processing time desired by the operator. It is also possible to quickly and humanely euthanize fish once settings appropriate for local water conditions have been determined. Studies have shown that salmon can be successfully anesthetized multiple times without any detectable injuries or effects on gamete quality. Also, for fish destined for commercial markets, proper settings can ensure the highest quality fillets.
