You suppose incorrectly... Lionfish are more often than not assumed to
have gotten transferred via transport in large ship ballast water, like

"There is no evidence to suggest that ballast water is a source for the
lionfish invasion although it is a common source of many marine
invertebrate introductions."

There was also a confirmed release of lionfish in 1992.

You're right. They are only worth $30 or so.
