In this collection we provide this needed depth of study of the key aspects of the invasion process for the spiny water flea, Bythotrephes longimanus.

Biol Invasion (this issue), Weisz EJ, Yan ND (2010) Relative value of limnological, geographic and human use variables as predictors of the presence of Bythotrephes longimanus in Canadian shield lakes. Other invaders arrived by the same route as the spiny water flea, in the ballast tanks of oceangoing freighters. Bait buckets and live wells can also host spiny water fleas, making it more important than ever to properly clean boats and trailers, drain live wells, and dispose of live bait properly, before leaving or entering a boat landing. And in 2017, a United Nations regulation mandated that all new ships be equipped with ballast-water treatment systems. Spiny water fleas have recently invaded two of the large lakes within Voyageurs National Park (Rainy Lake and the Namakan lake).

We do so by presenting the results of the work conducted by researchers in the Canadian Aquatic Invasive Species Network (CAISN), and several of their American and European collaborators over the past half decade. The spiny water flea, an invasive species, has been found in Lake George, just weeks after its discovery in the Champlain Canal, according to the state Department of Environmental Conservation. The spread, establishment and impacts of the spiny water flea, Bythotrephes longimanus, in temperate North America: a synopsis of the special issue. These water fleas eat zooplankton, a food also consumed by native fishes. 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. Prior to entering inland lakes, paddlers should wipe down all boats and gear that have … The spiny water flea is presently found only in Lake Superior. Fish and Wildlife Service examines possible routes by which the invasive zooplankton species, spiny waterflea, might reach Lake Champlain, as well as options for trying to prevent such spread. Norman D. Yan. Most people don’t care.” One recent study found that the spiny water flea wiped out three species of plankton in a single lake in northern Ontario. Conserv Biol 7:686–700, Grigorovich IA, Pashkova OV, Gromoca YF, van Overdijk CDA (1998) Bythotrephes longimanus in the commonwealth of independent states: variability, distribution and ecology. The main diet of spiny water fleas is other zooplankton. There should be much of interest in the collection for aquatic ecologists and invading species biologists alike. Previous studies have shown that over 40% of northern Minnesota lakes provide suitable habitat for spiny water flea, and human recreational activity is believed to be the primary vector of spread. Spiny and fishhook waterfleas can affect recreational angling and commercial fishing. It’s an unintended ecological experiment gone haywire, unfolding before our eyes, with unknown outcomes. Part of Springer Nature. It is imperative to keep ships clears of debris or mud that could harbor them. This is a preview of subscription content, log in to check access. Spiny waterfleas spread by Scientists and activists studying invasive species say the spiny water flea is spreading to more lakes in the Adirondack Park. Visitors to the park can help keep our inland lakes free of spiny water flea by following a few simple procedures. We thank Julia Dewing for her secretarial, administrative, and organizational work. Hydrobiol 590:3–14, Parker Stetter SL, Witzel LD, Rudstam LG, Einhouse DW, Mills EL (2005) Energetic consequences of diet shifts in lake Erie rainbow smelt (Osmerus mordax). Unlike Daphnia and other native grazers, the mussels strain nearly everything from the water column. Spiny water flea populations can become so dense that they even plague fishermen, clogging lines with gooey blobs that prevent the line from passing through the eyelets on a fishing rod.

It’s now established in dozens of smaller lakes across the entire region, where it feeds on Daphnia and other zooplankton, ripping them apart with its mandibles. People spread spiny waterfleas primarily through the movement of water-related equipment. It’s a visual predator, with a single black eyespot, prominent mandibles, and a barbed tail that makes up about 70 percent of its length. Rinsing with 140°F degree water is also believed to be effective in killing spiny water fleas and reducing the risk of spread. Since 2008, all ships entering the St. Lawrence River from the Atlantic have been required to flush their ballast-water tanks with salt water, which kills any freshwater creatures that might have hitched a ride. The plankton die-off in turn has affected yellow perch, walleye, and other native game fish. Biological Invasions 13:2423. Recent reports of spiny water fleas becoming snagged on fishing gear used on Lake Champlain have prompted officials from the Vermont Fish & Wildlife Department and the Lake Champlain Basin Program to urge anglers and boaters to take appropriate steps to prevent the spread of this and other harmful aquatic invasive species.

SWF are only 1/4”-1/2” long with a translucent body.
