In an effort to get rid of the Eurasian Ruffe, it has been banned for sale and bait use, and the public has been given orders to kill the Ruffe if they catch it.
Scientists have also been working to develop a piscicides that would kill the ruffe, but leave other fish alive
It has been proven that the food web of the ruffe has not changed after it's transfer
The Eurasian Ruffe is a small fish ranging from around 25cm each, however it is able to damage and ruin the lives of many other species in the water, such as competing for food, taking habitats and eating the eggs of fish. They do not have many predators, they reproduce and mature very quickly and they can adapt to a wide variety of conditions in the waters
The Eurasian ruffe is prey to very few animals due to the spikes on it's head, they swim around in deeper, darker water to avoid predators and they go to the shallow water at night for food.
The native habitat of the Eurasian Ruffe is northern Asia and Europe, or Eurasia. It is believed it made it's way to North America from a ballast vessel from Europe in the mid 1980's
Native Habitat of the Ruffe
New Habitat of the Ruffe
The first ruffe sighting was spotted in the great lakes of North America such as Lake Superior, Michigan and Huron, they are now seen in several other places in ontario such as the Kaministiquia River near Thunder Bay
It's tactics may have changed but it's diet hasn't. The Fish now spends it's lives in the great lakes of North America, it does the same thing a normal fish would do except it wins the competition every time, it get's it's food first, it reproduces first and it's the last one to die, only huge fish such as sharks and whales eat the Ruffe due to the hard spikes on it's head, making it hard to chew unless it has a big mouth.
