spiny water flea native habitat

The first report of spiny and fishhook waterfleas in North America were both in Lake Ontario – spiny waterflea in 1982 and fishhook waterflea in 1998. Local Concern: The spiny waterflea causes major changes in the zooplankton community structure, reproduce rapidly, and compete directly with small fish for food. Today, they are found in Lake Mille Lacs, Lake of the Woods, and Lake Vermilion. The invasive ingests all the zooplankton, and when the fish turn to it as an alternate food source, they choke on its' long spine. As of January 1, 2016, the possession, sale, or transport of this species in Alberta is illegal under the Fisheries Act. The species has since expanded its range to . Though the majority of the water flea's population is female, it is capable of asexual reproduction as well as sexual reproduction. Summary of Invasiveness Top of page. Native to St. Petersburg, Russia, spiny water fleas have wreaked havoc on zooplankton populations throughout the Great Lakes. The spiny water flea's diet consists of only small zooplankton, which is a big problem in the Great Lakes, seeing as many native fish rely on the microscopic organism to survive. Spiny Water Flea. Spiny waterfleas live in fresh water habitats and prefer cold temperatures, but can tolerate both brackish and warm water. “You can put them in chlorination for a few days, and they can survive that,” Branstrator said. Impact. However the water flea has spread in recent years to many areas throughout Europe It was introduced to the North American Great Lakes through ballast water and has since spread to a number of inland lakes. They are commonly found in Lake Ladoga, near the Baltic Sea in Russia. It is native to freshwater lakes in northern Europe and Asia. Infestations of spiny waterfleas negatively impact native fish populations, aquatic habitats and sports fishing. It is native to fresh waters of Northern Europe and Asia, but has been accidentally introduced and widely distributed in the Great Lakes area of North America since the 1980s. This invasive species outcompetes native species for food, which can have cascading impacts to the entire food web. They have been confirmed in the Laurentian Great Lakes and in some inland lakes in Ontario and Minnesota including Lake of the Woods.

If predation by Bythotrephes results in reduced populations of preferred prey, such as Daphnia , the water flea may result in negative consequences to native Great Lakes fish populations. Preferred Habitat: It can typically be found in open water in lakes. Researchers found it in a canal that connects Lake Champlain to the Hudson River, and then a fisherman found it in Lake George, an Adirondack lake located about a half-mile upstream from Lake Champlain. They feed on tiny crustaceans and other zooplankton that are foods for fish and other native aquatic organisms, putting them in direct competition for this important food source. Spiny water fleas are native to Eurasia and were probably brought into the Great Lakes in the ballast water of ocean-going freighters. Bythotrephes longimanus, the spiny water flea, is a predatory cladoceran native to northern Europe and Asia.

Has caused a decline in the population of zooplankton as a result of predation (Vanderploeg et al. Reason for ANS Designation: This zooplankton can outcompete other zooplankton for food and change the types of zooplankton available for fish prey. Vermont received bad news recently when we learned that a new aquatic invasive species, the spiny water flea, was found in Lake George as well as in feeder canals to However the water flea has spread in recent years to many areas throughout Europe including some ports and inland lakes outside its natural range through the ballasts of large ships. B. longimanus, commonly referred to as the spiny waterflea, is an invasive crustacean zooplankton in the Great Lakes region of North America and areas of Europe.Its native range encompasses large areas of northern and central Europe and Asia. Bythotrephes longimanus (also Bythotrephes cederstroemi), or the spiny water flea, is a planktonic crustacean less than 15 millimetres (0.6 in) long. Oddly enough, spiny water fleas are considered zooplankton themselves. They can tolerate brackish water and prefer cooler water temperatures. A carapace (shell) covers most of its body. In Vermont, spiny waterfleas are currently found in Lake Champlain. They were first found in Lake Superior in 1987 and first discovered in inland Minnesota lakes in Island Lake Reservoir north of Duluth in 1990. Native Range: Northern Europe and Asia.
