Did you know?

  1. You can tell the grass carp from the bighead and silver carp by the grass carp’s larger scales.
  2. Grass carp are plant-eaters, unlike their filter-feeding cousins. Imported to the U.S., they became invaders after being released intentionally to control weeds in aquaculture ponds.
