2 new species of Krefish identified in Pacific Northwest – and they are already at risk

Two new species of Krefish have been identified in the Pacific North -West region of North America, and researchers say the two species are in the grip of extinction.

One of those crafish is called “unfortunate crayfish”, which is mainly found in Central Oregon, according to biologist Eric Larsen.

Other, Oknagan Krefish, BC’s Oknagan is well found in the lake.

Larsen said that both were first considered wrong for the Signal Krefish of the most common species of Krefish on the West Coast.

Larsen told CBC, “They are a completely new species. This is the first time someone has called this animal Okegon Crafish,” Larsen told the CBC Debreak south Host Chris Walker.

The easiest way to separate signal variety from the other two is a specific white scar on the claws of signal crafish.

“If you find that absent or really less, it may suggest that you are looking at Okegon Krefish,” Larsen said.

Professor Eric Taylor of Zoology at the University of British Columbia said that it is important to identify various species, even though they appear very similar for many reasons.

“Knowing is like an underlying value,” he said. “Humans like to know about the world around us, including the natural world, so it is important for the accurate understanding of the level of biodiversity we have.”

Additionally, it helps researchers better understand the ecosystem in which these species live.

Thirdly, identifying individual species gives an idea of ​​how broad the species is. For example, Taylor said, a strong effort to protect a species can be if it is found only in a small area, as opposite to an area.

Risk of extinction

According to Larsen, Okegon and unfortunate crayfish is already considered to be extinct.

Taylor said that it is not surprising, given that these are small groups that were once thought as a large population.

He said, “The smaller an animal or plant, the more chance there is that if something bad happens, it is going to be extinct,” he said.

Oknagan Crafish is particularly a matter of concern, said, because it is located in the Oknagan Lake – a region of “high human impact”.

Larsen hopes that the status will inspire protection action.

“Crefish doesn’t meet that well,” he said.

Larsen said, “We have shifted Krefish for centuries,”, pointing to stocking lakes with Crafish, used them as fodder and even left the classrooms in the wild.

Similar to invasive muscles, they can also hold a ride for a new location on boats.

Larsen said, in particular, scientists are concerned that Okegon Krefish would be displaced by aggressive rare crafish, while the unfortunate crefish may disappear due to aggressive rust.

This is a huge risk for unfortunate crayfish in Oregon that is a rusty crayfish from eastern North America that is actually spreading rapidly in its original boundary. But for Okegon Crafish, we wanted to discourage the movement of other Crafish in our population.

Not only aggressive species can be harmful to the native of Pacific Northwest, they also feed fish eggs and destroy aquatic plants, Larsen said, as well as damage to infrastructure such as irrigation canals and dams.

Investable Crafish can also be done DiseaseAccording to the department of fisheries and oceans.

“They pursue the shocking amount of sediment. So you want to be really careful not to introduce Krefish to new places.”
