METRO VANCOUVER — Burnaby park officials are investigating the reported sighting of a snakehead fish at the lagoon in Central Park.
“We haven’t actually witnessed it ourselves,” Don Hunter, assistant director of Burnaby parks, said Tuesday. Staff have contacted the ministry of the environment and a biologist to try to identify the fish supposedly sighted last weekend, he said.
A person made a recent video and posted it online with the comment: “Was at Central Park on Mother’s Day, took a walk around the lagoon to check out the carp and Koi. To my surprise I spotted a snakehead fish, a very large one.”
Snakeheads can grow up to a metre long, weigh six kilograms and a spawning female can release up to 15,000 eggs at once, mating up to five times a year.
They are voracious predators with teeth that eat other fish and small mammals.
Michael Russello, an associate professor of biology at the Okanagan campus of the University of British Columbia, said it’s possible the fish could have been dumped out of a fish tank, which is what happened in the U.S.
“It’s a big problem down in the States,” Russello said. “They have a primitive lung that allows them to move across land to other water bodies,” he added.
“They’re very scary. They’re an ambush predator. They can take a small dog.”
The invasive species is a top-level predatory fish that comes from Asia and Africa.
It has been spotted in Ontario and is able to live out of water for slightly less than an hour while it slithers across land, seeking more ponds and lakes to invade.
Chris Harley, an associate professor of zoology at UBC, said he was shocked to find that snakehead fish are being sold live at the T&T market in Richmond.
“It doesn’t make sense to cater to live sales,” he said, adding it increases the risk of the invasive species being released into local waters.
He said some Buddhist temples release live seafood, in an act called “emancipation” to bring good karma.
Jonathan Moore, an assistant professor of biology at Simon Fraser University, said he would like to see a ban of live sales of snakehead fish.
“Many states [in the U.S.] have very strict controls on live fish sales, including live bait,” he said.
If the Burnaby sighting is confirmed, he said, “it’s something to be concerned about” because once an invasive species gets established, it’s difficult to remove.

The snakehead fish: Someone out for a stroll on Mother's Day saw one in the lagoon of Burnaby's Central Park and has posted it online.

Live snakehead fish being sold from tanks at the Osaka Market in Richmond. Some U.S. states have banned or severely restricted sales of live fish such as snakeheads, a voracious invasive species.

These invasive periwinkle sea snails ((Littorina littorea, native to Europe) were found in Stanley Park. They are sold live at local fish markets.

Just tell the Chinese that they could go catch the snakehead fish for free, problem solved.

The Chinese will not do that, since they do not like this type of fish, or anything that is free.

You should tell the Indians or Filipinos do that, problem solved.
Just tell the Japanese, they will eat any fish for sashimi.

係架~ 一叫D中國人去捉, 就咩都可以比人捉到絕種架啦!
我契爺同契媽30幾40年前過來, 佢地話以前响English Bay, 同埋好多沙灘都可以捉到象拔蚌同埋蜆, 但就係俾D中國人捉到無晒咋嘛! 有D人仲夠膽死捉埋 Canadian Goose 同埋 raccoon 食添! 話當D raccoon 係果子狸wor! 海鷗我都聽過有人捉過來吃呀!
