RUFFE
The Ruffe can live in a wide range of environmental conditions. In their native range, they can be found in fresh and brackish water. They do well in a variety of habitat types including lakes, large and small rivers,estuaries, and ponds. They eat aquatic insects, bottom dwelling organisms, and occasionally the eggs of other fish which helps them grow quickly. Their well-developed sensory system allows them to feed at night as well as to hide in darkness to avoid predators. Maturing quickly especially in warm water, a female can start reproducing at age 2 and a male after just one year. The eggs will hatch in 5 to 12 days. There is generally little predatory pressure on the Ruffe. Few species will feed on them, only doing so if other food sources become scarce. Ruffe live an average of 7 years but have been known to live up to 11 years.
The Eurasian ruffe was first collected from the St. Louis River, a tributary to Lake Superior. The ruffe is now in Lake Superior, Lake Michigan, Lake Huron, and many of their tributaries. It is unclear how the ruffe first got into North American waters but the prevailing thought is that it was introduced through the ballast water of transoceanic ships originating from European ports.
B3.5 Identify various factors related to human activity that have impacted on ecosystems (the introduction of invasive species) and explain how these factors affect the equilibrium in an ecosystem.
