Dunnville, Ontario. – Finally, something to unite President Donald Trump, his democratic opponents and Canadians, whom he threatens the application: fiercely hungry carp.

Invasive carp, sometimes called Asian carp, was introduced in the United States in the 1970s. And they never ceased to spread – and there is everything in their path – since then.

“They eat cars,” said Trisia Tugaade, a water biologist from the Canadian carp program, since she and her team glided along the Grand -River – the tributary on Lake Eri, are looking for fish that experts are afraid of great lakes.

Since they can eat 40% of their body weight per day, invasive carps were originally considered as an instrument for monitoring algae troubles in limited areas, such as ponds for aquaculture.

But they probably escaped during the flood and made their way to the north, including through the Illinois River. This raised the ghost of the destructive pier based on the Great Lakes, the world's largest freshwater system in the surface of the surface.

“There is nothing that I saw that it scares ecologists more than to look at what effects would be influenced if the types of Asian carp are in the Illinois River, fall into the great lakes and form AFP of the propagating population,” said AFP Water Policy at Michigan University Mike Srieberg.

This is a threat that attracted Trump's attention, who calls the fish “threat” and specialists on both sides of the border.

Shock processing

Every year, Canadian experts are looking for carp in the tributaries of the great lakes, which are considered favorable for spawning and feeding – often herbaceous areas with warmer small water.

In the Grand -River Tugaade and senior biologist Alex Price watched the electrophication mission.

The team lowered two roads into the water, which released non -lethal pulsating charges, stunning the fish and allowing them to bring with nets to the tank on board.

The fish was identified, measured and – if it was not considered invasive – released in dirty water.

Since the launch of the program in 2012, only a few dozen invasive carps have been captured in Canadian waters.

James Hall, whose sports fishing Hall'emin takes customers on Lake Eri, told AFP that he was one of the first to catch him.

“I was wondering what it was, but I knew that it was something else,” he said, describing the moment when he pulled the carp ten years ago.

Hall said that he laid fish on ice and called the state hot line of the carp.

The invasive carp “was very rare to catch what was great,” said Price, while insisting that vigilance was necessary, given the seriousness of the threat.

“They can breed several times a year and produce hundreds of thousands of eggs in one event,” he said AFP.

“During the first year of life, they can be too large for our natural predators,” he added.

Broken?

Srieberg described the great lakes as “great martial workers” in American political parties and between Canada and the United States.

Protecting them from invasive species has become a two -party priority in the States on their shores, some of which were historically selective states of electoral swing, such as Michigan, Ohio, Pennsylvania and Wisconsin, ”he said.

Trump’s White House memorandum, confirming his support for efforts against the “economic and environmental threat of invasive carp,” brought praise compared to praise.

“We are in the most politically controversial times that I saw in my life,” said Sriberg, calling Trump's “quiet” Trump's “quiet” Trump confirmation of the rare bicopartican nature of the policy of great lakes.

But this path forward is unclear.

Trump’s trade war and the threat of annexation strained the relations of the USA-Canada. Earlier this year, the president was reported, told the former Prime Minister Justin Trudeau that he wants to revise agreements governing the Great Lakes.

Srieberg noted that the joint management of the water route determined relations with Canada, but said: “The hostility of the Trump administration in relation to Canada … threatens to defeat it.”

If the battle with an invasive carp failed, the consequences would be both terrible and unpredictable, he added.

“This will lead to sharp changes in the ecological balance of water,” said Srieberg.

And if they once became based on the great lakes, “I do not believe that you will have a chance to actually eliminate the population,” he said.
