What is the maximum range of the duty cycle in electrofishing?

The maximum range of the duty cycle in electrofishing is typically defined as 10 to 20%. The duty cycle refers to the proportion of time that the electrical current is applied in relation to the total cycle time; this is crucial for effectively stunning fish without causing them harm.

During electrofishing, maintaining this duty cycle range allows for a balance between effective fish capture and minimizing stress or injury. A duty cycle that is too low may not be effective in stunning fish, while a higher duty cycle can lead to potential risks, such as mortality, especially in sensitive species.

Understanding the correct duty cycle range is vital for ensuring both the efficacy of the electrofishing operation and the welfare of the aquatic organisms being studied or harvested. This optimal range is broadly accepted in guidelines and practices related to electrofishing, supporting the answer provided.
