Fish 'shout' to be heard above human noises

[MoCarp]

This was interesting....

"Humans are noisy creatures, our cacophony of jet engines and jackhammering drowning out the communications of other species. In response, a number of animals, including marmosets and whales, turn up their own volume to be heard above the din, a phenomenon called the Lombard effect. A new study reveals that even fish “shout.” Researchers took a close look at the blacktail shiner (Cyprinella venusta), which is common to freshwater streams of the southeastern United States and whose short-distance acoustic signals are often exposed to boat and road noise. Only male shiners make sounds; popping sounds called knocks are used aggressively toward other males, while staticky-sounding “growls” are used for courtship, both heard in the above video. When the scientists brought the fish back to the lab and cranked up white noise from an underwater amplifier, they found that shiner males emitted fewer, shorter pulses, and cranked up the volume of their acoustic signals to be heard above background noise. Published in Behavioral Ecology, it’s the first study documenting the Lombard effect in fish, suggesting that freshwater fish are another group potentially impacted by our ever-increasing hubbub."

lol NO thats work man..........I know lots or weird fish studies...drum make lots of noise...and Flatheads do as well, watch them at bass pro tank everything gets outta their way when they get to snapping their jaws...studies on fish communication is just starting...it is rumored some bass pros have played the sounds of fish feeding on shad through a subwoofer mounted like a transducer. It would be a rocking $ invention!!!! Its my understanding some big money electronics companies are funding research of this type...

"I swear I would have set the hook, but that smallie shouted so loud at me that I got startled and just forgot." 

-My excuse the next time I miss a nice fish.

Well do have Rattle in some Lures to attract Fish. Makes sense.

I know land Mammals if there is a sudden loud noise they will just hold tight if they can't tell what it is.

Rain to me is great, softens Leaves and Deer can't hear as well. Turkeys will head for open fields.

Jet Boats going through shallows on the river there will be a Feeding Frenzy after they go through but this is same as shuffling.
