Designed for application in hatchery settings, the EA-1000B allows large
numbers of fish to be quickly and inexpensively anesthetized without
the use of chemicals. This technology allows the immediate release of
sedated fish with no mandated withdrawal period.

Electrosedation as a technique for processing large numbers of fish offers a viable alternative to the use of chemicals. It
is safe, fast, effective, and inexpensive to use – as compared to labor
intensive handling protocols.

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.
