In which scenario is a generator preferred over a battery for electrofishing?

A generator is preferred over a battery in large water bodies where extended operation time is necessary because generators can provide a continuous and stable power source for longer periods compared to batteries. In electrofishing, the duration of operation can be critical, especially when conducting extensive surveys or targeting specific areas over a prolonged time. Generators can supply a higher and more consistent voltage output, which is essential for effective electrofishing across vast areas, ensuring that the electrical field remains effective throughout the operation.

In contrast, batteries have a limited charge that can deplete quickly, especially if the equipment is used continuously. While they may be handy for quick operations or in smaller bodies of water, they are not ideal for extensive use where the electrofishing efforts require sustained power for multiple sampling sites or longer periods. This is particularly relevant in research settings where the efficiency of capture and data collection is paramount.
