When will people learn NOT to introduce aquarium raised fish into local waters? We have enough to worry about when it comes to the potential disaster the Asin carp could bring us! The artical suggests that the snakehead couldn’t survive a cold winter such as we have up here… but you never know. Fish can be extremly adaptable at times.
On a side note… that snakehead could be pretty easiliy mistaken for a dogfish… albeit a colorful dogfish.
