“90% of everything is carp.” Thanks to my colleague Eric Zolt for the joke, though according to one study cited in the Asian Carp II Seventh Circuit case, 95% of everything is carp. (“A fish kill conducted near St. Louis in 1999 showed that the Asian carp constituted over 95% of the biomass in the Mississippi at that place and time.”)
