Adding "Chesapeake" to it is the marketing ploy.

As far as I know all 50 species are called  snakeheads, that may be the Latin translation of Channidae, I don't know much at all about them, but had looked them up when my son who used to live in Fl. described them to me. Hopefully the Northern Snakehead is the only one that gets stocked in N.America, we really don't need any more invasives. The name ought to be Invasive Channa.

There is also the bullseye snakehead, Channa marulius, down in FL. Not sure if there are any other established species in the US.

That is true. They are in all the rivers and tributaries surrounding the Chesapeake Bay. They are also in the Delaware River watershed now as well.
