 Marine noise pollution stresses and confuses fish Date: August 10, 2017 Source: Newcastle University Summary: Increased noise pollution in the oceans is confusing fish and compromising their ability to recognise and avoid predators. Researchers at Newcastle University (UK) found that European sea bass experienced higher stress levels when exposed to the types of piling and drilling sounds made during the construction of offshore structures.
The fish also showed signs of being confused when they encountered a potential predator while exposed to these underwater noises. When researchers played recordings of piling sounds and mimicked an approaching predator, the seabass made more turns and failed to move away from the predator. When exposed to drilling sounds the sea bass actively avoided these areas, spending more time in what the research team called the 'safe zone'. The fish also took longer to recover from exposure to the underwater sounds. Lead researcher Ilaria Spiga explained: "Over the last few decades, the sea has become a very noisy place. The effects we saw were subtle changes, which may well have the potential to disrupt the seabass's ability to remain 'in tune' with its environment.

Underwater creatures are really amazing. I am not into them, but I do believe that they are creatures that must be well cared of. I have read some article that tells about the cause of the water pollution to the fishes. Most of the trashes and plastic stuffs that we throw at the water cause fishes to die. Let us stop being immature and start becoming a mature and responsible citizen. Anyway, I have to admit that the picture of the sea bass above is quite scary for me. 12/21/2018 04:49:43 am
The noises that we humans create on the surface greatly affects the behavior and health of other species here on earth. Marine life is extremely sensitive when it comes to noise because their eye sights are not sharp. They mostly navigate through their other senses like hearing and feeling the surrounding of the area near them. We humans must be more aware of the negative things that we bring upon other species, especially marine life because they are much more sensitive and endangered. Leave a Reply. |
