 Title: "Farting Fish Keep in Touch", by Mary Beckman
 It seems that herring have great hearing and to investigate
 this further Magnus Wahlberg, now at Aarhus University in
 Denmark, and colleagues reported earlier this year in
 "Aquatic Living Resources" (exact reference not given) that
 herring emit air bubbles from their anuses when scared or
 during ascent or descent.
 Further investigations by Ben Wilson of Simon Frasier
 University in British Columbia, Canada, correlated the
 herring anus bubble blowing with emitted sounds. The sounds
 have been denoted as "Fast Repetitive Ticks" (FRT's). Further
 information and a sound file can be found at Ben Wilson's
 web page:

 Wilson and colleagues found that the FRT'ing appears to serve
 a social function because the herring made this particular
 noise, when they gather, just as darkness was falling. They
 also found that herring need to gulp air at the water surface
 in order to sustain FRT'ing. More details are reported online
 at "Biology Letters" (05 Nov 2003).
