Will Noise Really Scare The Fish Away?

Has anyone ever told you to be quiet in case your chatting scares the fish away? Is it even true that fish can hear underwater? The fact is, you don’t actually need to be still and silent when fishing as general noise will not likely scare fish. That being said, will the noise of your generator frighten the fish away? And if so, what can you do about it? Catch your prey with these noise-cancelling tips for fishing.

Fish can hear you talk. Sort of…

Yes, it’s true, fish can hear you talk. However, this should only be an issue if you’re shouting. Noises produced above water aren’t usually forceful enough to pierce the surface tension of the water. Therefore, distinctive sounds or general chatter may not disturb fish to the extent to which you may have been led to believe. For that reason, your voice is unlikely to disturb fish.

So, should you fish quietly?

Sounds emitted underwater are far more likely to disturb fish. Underwater sounds transmit vibrations rapidly - at about four times the speed of vibrations relayed through the air. Although fish do hold the ability to hear sounds, their hearing abilities vary among different species. Fish tend to depend on vibrations to recognise their environment. An example of this would be when identifying potential predators. While conversation and commotion may not frighten fish away, loud distinctive sounds emitted by your boat’s generator could do so. This is particularly true of two-stroke outboards, which produce loud clanging sounds when moving components come into contact with one another. When selecting an engine for your boat, it is therefore crucial that you choose one that emits minimal vibrations.

Purchase a motor that allows you to fish in peace.

You may find electric outboard motors to be a sufficient alternative to internal combustion motors, the latter of which are inclined to produce more sound. One option is ePropulsion’s Spirit 1.0 Plus, a portable 3HP electric outboard constructed for dinghies and fishing boats. The electric outboard, engineered with premium anodised and powder coated aluminium, is appropriate for both fresh and saltwater use — ideal for bass fishing. The outboard’s 1,276-Wh large integrated lithium battery will last all day at trolling speed.

The Spirit 1.0 Plus is recognised for being silent and nearly vibration-free. Operating on a brushless DC motor, a quieter option over brushed motors, it requires less power to function.

Moving on from boat motors, a fish finder - an apparatus that generates and dispatches a sound wave through open waters to locate fish - emits a loud underwater vibration and may also present issues with frightening fish. In fact, when fishing, you may want to avoid utilising a fish finder altogether.

Stop scaring fish away with these top tips.

Propeller-driven propulsion and underwater electric motors can be heard by all varieties of fish. But there are ways in which you can reduce and keep noise to a minimum. Prior to fishing, ensure your motor is tightly fastened to the boat. A motor not fastened correctly may emit excessive vibrations. The ePropulsion’s Spirit 1.0 Plus boasts a lightweight structure at less than 20kg, making it convenient, transportable and simple for attaching to a boat.

It’s also a good idea to consider travelling at lower speeds, as greater propulsion generates more sound. When fishing in shallow areas, try running your motor below 50 percent. This will allow you to retain a firm pace, all the while producing steady sound which fuses into the background, causing fish to adapt to the noise. Any changes in speed should be carried out gradually.

The ePropulsion Spirit 1.0 Plus allows you to digitally adjust the maximum power output, allowing for greater control of your boat’s speed, and the noise it produces. The ePropulsion Spirit 1.0 Plus also has a folding tiller, allowing for more convenience once you have set your desired speed.

It’s also important to limit the number of times you turn your motor on and off, to reduce noise. The ePropulsion Spirit 1.0 Plus, works to your advantage once again, as the engine starts with one simple push of a button.

When you are out fishing, it's important to ensure your propeller stays far below the surface of the water. This prevents splashing. With ePropulsion’s Spirit 1.0 Plus, you have the option of both short and long shaft length options. Anyone wishing to remain undetected may find the long shaft beneficial.

In conclusion

It’s best to exercise caution when fishing. Avoid making too much noise where possible. Keep your voices down and have music levels low. Most importantly, though, choose an electric outboard that emits minimal vibration and ensure you utilise your outboard’s features effectively.
