Asian fish species prompts President Donald Trump to issue urgent warning to the US

Asian carp are thriving, threatening the Great Lakes ecosystem. The US government is worried about the threat of “dominance” by this invasive species.

The Asian carp has brought US President Donald Trump, his Democratic political opponents and Canadians to a common cause. Asian carp, sometimes called invasive carp, were introduced to the US in the 1970s. Since then, they have been thriving and eating almost everything in their path.

“They are predatory machines,” said biologist Trisiah Tugade, who works with Canada’s invasive carp program. She and her team often visit the Grand River to look for the fish they fear will wreak havoc on the Great Lakes. Photo: kaptur.house.gov.

Because they can eat up to 40% of their body weight each day, invasive carp were initially seen as a tool to control harmful algae in enclosed areas, such as aquaculture ponds. Photo: SandmanPhotography/Shutterstock.

However, Asian carp have escaped, possibly in floods, and moved north, raising fears that the predatory fish could dominate the Great Lakes – the world’s largest freshwater system by surface area. Photo: greatlakesnow.org.

Every year, Canadian experts conduct a series of operations to track Asian carp in tributaries of the Great Lakes, where the environment is favorable for spawning and feeding, often in grassy areas with shallow, warmer waters. Photo: news.wttw.com.

On the Grand River, Tugade and colleague Alex Price monitor electrofishing operations. Since the program began in 2012, only a few dozen invasive carp have been caught in Canadian waters. Photo: Evan Garcia / Chicago Tonight.

Previously, a White House memo in May showed President Trump supporting efforts to combat the “ economic and ecological threat posed by invasive carp.” Photo: Evan Garcia / Chicago Tonight.
