From what I’ve read there
are two species of carp
invading the Missouri river.
Big Head, and Silver carp.
They both prefer to spawn
in long stretches of fast
moving water, and basically
hatch on the move.
The silver carp are the ones
that get airborne due to boat
motor vibrations.

There was an episode of Swamp People this year where Silver Carp were used as gator bait. A good food source like that could create a gator problem..

Silver and Bighead -- that's what I've read. There are two more types of invasive Asian carp also, yet the numbers of those are small in comparison to silver, and bighead carp.

Grass carp --and if memory properly serves - Black carp. Anecdotal info suggests the Grass carp is better eating than the others, desirable even (instead of in lesser way simply "acceptable", sort of like tilapia is for my own tastes).

Thanks for the info on spawning characteristics.

"...long stretches of fast moving water, and basically hatch on the move."

Maybe you intended to convey "spawn" on the move instead of "hatch" on the move? But while we're at it, I'll inquire out loud; How long for fertilization to become hatchling? Seems like the little 'ol things would be far downstream when they first began swimming on their own.

Long stretches of fast water...and here I was thinking the carp maybe went for eddies to spawn in, off to the side of main flows.
