Follow-up experts followed with enthusiasm as it moves in hidden state clips-here can spoil the local economy

Alaska’s virgin waterways have always been a haven for original fish – but now, an unexpected threat is frequent in this water, which disrupts the silence of the silence that has been present for generations, as reported. travel.

What is happening?

Alaska waterways are being attacked by unexpected invaders: The Norter Pike.

This razing predator moves secretly among the ecosystems of fresh water, and removes original fish groups. Scientists have discovered that PIKE can now travel through salt water, breaking the previous assumptions about their movement.

The researchers first follow the movement of fish by analyzing srostium in their ear stones, a method that provides indisputable evidence for its migration. Matthew Waller, the lead author of the study, explained: “Strintium varies according to geology and location. If Pike is moving between the water gatherings, you can capture it by analyzing the stretium in Olith,” said Matthew Waller, the lead author of the study.

Why is the North Pike related?

The invasion of Northern Pike threatens accurate aquatic ecosystems in Alaska.

Since the fifties of the last century, these fish have populated 150 illegally different flat, targeting salmon and events. They were presented by people looking for more sporting hunting opportunities, but the consequences were destroyed. As he wrote, the expansion of Northern Pike “causes the original fish to diminish the region” – which can have a tremendous impact on the industries of hunting restaurant and local seafood.

Xinuk salmon and Salon Coho and the thickness of salmon dramatically decreased. These original fish are devour before adulthood, which may push them towards extinction. North PIKE consumes juvenile fish quickly so that the entire generations are in danger.

“These residents never have an opportunity to increase because many do not reach adulthood,” according to travel, which is a serious concern “for all of the ecosystems of fresh water as well as the local economy.”

What is being done about the northern comfort?

The Sports and Fish Department in Alaska is fighting. Using methods like Gill Nets, it is successfully removed from the northern comfort of more than 25 waters – although the gills networks are known to harm other species.

One hanging Proposal An innovative approach: “Cash incentives for fishermen, along with other programs”, can help compensate for costs and Society involved.

But the challenges remain. Chemical treatments are limited due to Fears about drinking water It seems that the removal of complete comfort is almost almost impossible. With 150 sites inhabited by these predators, time is running out for the original fish in Alaska.
