Lake monster caught in pond

The battle against an invasive predator known as the snakehead or Frankenfish isn't over, says B.C.'s environment minister.
Only hours after biologists netted the fish from a Burnaby, B.C., lagoon, Terry Lake vowed to change provincial regulations by the fall to ban its live importation.
"This is a voracious predator," said Lake. "It has no natural enemies in this environment. And so left unchecked, it could devastate ecosystems, and native species would really suffer."
Officials were tipped off to the snakehead's presence last month after a video was posted to YouTube and at about 11:15 a.m. Friday biologists caught one of the fish in Central Park.
Matthias Herborg, an invasive species expert with the Ministry of Environment, said officials used a small dip net to capture the snakehead, which measured two-thirds of a metre long. The lagoon where it had been living had previously been drained of much of its water.
The captured Frankenfish was strong, was writhing around, and took a while to euthanize, he said, noting the animal was big for the species.
"We're going to do some more work today just to make sure there was really only one in there," said Herborg.
To ensure the snakehead cannot be brought live into British Columbia, the government will now adjust its Controlled Alien Species Regulation to include the animal, said Lake.
The changes, which have to go through cabinet, but not the legislature, will hopefully become law by the fall, he said.
Snakeheads are native to fresh water in Russia and China and have few predators when fully grown. They could pose a severe risk to B.C.'s wild salmon stocks if they reached the nearby Fraser River.
They are also capable of breathing oxygen and squirming short distances over land.
