How long should fish be allowed to recover post-electrofishing before release?

Allowing fish to recover for approximately 1-5 minutes post-electrofishing is essential for ensuring their well-being before release. This timeframe is generally sufficient for most species to regain their equilibrium and reduce any stress levels induced by the electrofishing process. Recovery time can vary depending on factors such as the species being captured, water temperature, and individual fish condition.

Monitoring their behavior, such as swimming activity and responsiveness, is crucial during this period to determine when the fish are ready for release. Fish that are allowed an appropriate recovery period are more likely to survive post-release and continue to thrive in their natural environment.

Other options suggest either a shorter period or a fixed longer duration for recovery, which may not consider the variability among different species or conditions, thereby potentially compromising the fish's survival and health.
