Herrings converse via flatulence, researchers find

PARIS, Nov 11 (AFP) - Herrings appear to be sociable fish who like to communicate among themselves and use their natural flatulence to do so, a team of British and Canadian researchers has reported.

A report in the British review Biology Letters describes how the researchers studied the sounds produced by two kinds of captive, wild-caught herring.

"At night herring squeeze bubbles out of their swimbladders through an anal pore, producing sounds not unlike people blowing raspberries," the team of three recounts.

The Pacific species (Clupea pallasii) were found to emit distinctive bursts of pulses, known as fast repetitive tick (FRT) sounds, mostly at night, lasting between 0.6 seconds and 7.6 seconds in the 1.7 to 22 kilohertz bands.

"Digested gas and gulped air transfer to the swim bladder ... do not appear to be responsible for FRT sound generation," the report said.

It was the same story with Clupea pallasii's Atlantic cousin, Clupea harengus.

"Atlantic herring also produce FRT sounds and video analysis showed an association with bubble expulsion from the anal duct region (i.e. from the gut or swim bladder," the researchers found.

"The functions of these sounds are unknown but as the per capita rates of sound production by fish at higher densities were greater, social mediation appears likely.

"These sounds may have consequences for our understanding of herring behaviour and the effects of noise pollution."

Thus, one might surmise that all DU members are also herrings...

What's so unique about that Frat Boys have been doing that for years.

fast repetitive tick (FRT)

What an acronym for gas expulsion! LOL!

Is this a government research grant? Please tell me this is a joke...

"...producing sounds not unlike people blowing raspberries..."

Isn't this what a lot of our college students learn in their 'schools'?

Actually, the acronym used to be Fast Acoustically-Repetitive Tick, but...
