Scientists in central Europe report that native species of fish in Lake Constance are being disadvantaged of meals as a result of different invasive species, comparable to three-spined sticklebacks, and quagga mussels, have taken over the waters.
However to what extent has its ecosystem been impacted by these invasive species?
To seek out out, Euronews requested Piet Spaak, senior scientist at Eawag analysis institute, and SeeWandel challenge chief, about what the long run holds for Europe’s third-largest lake.
"If you're a fisherman, it is catastrophic since you lose your corporation, and you don't have any cash to stay from anymore. So it is a disaster.
"So in case you are producing ingesting water, it is a huge downside as a result of your pipes get clocked by quagga mussels. So it's a must to make investments, however you may clear them. And the water remains to be of top quality. So it is an issue that you may resolve. It is an financial price, nevertheless it's doable.
"If you're a diver and also you wish to swim within the water and to see the constructions underwater, you are possibly joyful as a result of the water is extra clear. So it completely relies on who you might be, during which place you might be. You can not say typically that is unhealthy or that is good.
"However should you have a look at the ecosystem, should you ask me as a biologist, as an aquatic ecologist, then I am not joyful in any respect. As a result of the ecosystem is modified and it is modified in a method that can't be modified possibly again. However it's a disaster for the ecosystem, however possibly not for all ecosystem customers. I hope that politicians collectively, in fact, with society, all people collectively takes measurements in order that what we've now in Lake Constance won't occur in all European prealpine lakes."
