British Columbia chinook salmon populations decline: scientists


The chinook salmon populations in southern British Columbia are declining almost half, according to the science commission that controls wildlife populations.

The Cambodian Wildlife Threat Committee was informed on Monday that 16 Chinook populations were analyzed, they are in danger, four are threatened and a concern is unique.

It is the only one located in the British Columbia Thompson River. The state of both populations is unknown.

Southern B.C. There are 28 Chinook populations.

Threatened is the most serious commission ranking, it is recommended to put people at risk.

"There are more than 200 other fish still in mind," said John Neilson, biologists and members.

"At that level, it would be a concern for stocks, so we are listening to the alarm."

Chinook salmon is one of the main colonies in British Columbia and is the center of indigenous livelihoods and culture. Neilson has had the biggest commercial review ever on fish.

"Salmon in other studies and general knowledge on B.C., there is a lot of concern," said Neilson. "These are extremists that need special attention."

Scientists believe that fragments of their life pass through the ocean.

Some believe that the growing number of seals and sea lions, those that eat fish, have declines behind them. Others say that the warming and acidification of the ocean depends on the salmon in the food web.

"The story is complicated," said Neilson. It's time for the federal government to protect its fish and its habitats, he added.

"Our suggestion is that the government can act quickly."

The Risk Law Species allows the federal government to provide emergency protection orders to control activity in Ottawa's critical habitat that governs the province.

The federal government has twice used power to the western coral frog and sage grouse.

The British Environment Minister, Catherine McKenna, said he had not yet seen the evaluation, but his concerns could continue.

"We believe that preserving and conserving our wildlife is important, according to the Law of Inclusion of Species of Reasons."

Several measures have been taken to protect and reconstruct Chinook salmon stocks.

Among 36 species, the commission evaluated white bears, who continue to be a special concern.

He also worked in black oak, urban parks in Toronto, Montreal and Ottawa. In the last 20 years, the invasive species called emerald-ash has killed two billion trees in the Great Lakes region.

Black bands are now threatened, the commission has found.
