bighead

Carp are voracious eaters — adult bigheads and silvers can consume up to 40% of their body weight in a day — and easily out-compete native species, wreaking havoc on aquatic ecosystems.

Four different species are considered invasive carp: bighead, black, grass and silver.

There are four types of invasive carp: bighead, silver, grass, and black.

It’s an abbreviated wordplay on “copious” — a reference to the booming populations of bighead, silver, grass and black carp in the U.S. heartland.

The four species described collectively as Asian carp — bighead, silver, grass and black carp — were brought from China a half-century ago to rid Southern sewage and aquaculture ponds of algae, weeds and parasites.
