Spiny and fishhook waterfleas prefer large, deep, clear lakes, but can also be found in shallower waters. Their tail spines catch on fishing equipment, making it difficult to reel in lines, and clogging commercial nets and trawl lines. Bythotrephes is typified by a long abdominal spine with several barbs which protect it from predators. Aquatic invasive species organizations are working to educate boaters and decrease the spread. The spiny water flea’s long tail can make it hard for small fish to handle them, but Bluegill’s detach the tail before consuming the organism, Walsh said. (2012). "It’s not just a fishing problem, it’s a problem that affects everything we do in the lake,". But, guess what! If you’ve seen an invasive waterflea or other invasive species in the wild, please contact the toll-free Invading Species Hotline at 1-800-563-7711, or visit. Their spiky tail keeps them from being consumed by smaller fish, which allows for high populations that outcompete native fish and zooplankton for food resources. Native to Northern Europe, the spiny waterflea probably arrived via ballast water.

The spiny waterflea has been found in all the Great Lakes and in more than 100 inland lakes in Ontario. Its average length is only about one centimeter, but its long tail spine (70% of animal’s total length) makes it easily distinguishable from other invertebrates and zooplankton. They do it through a process known as parthenogenesis or asexual reproduction, which means that they are capable of reproducing without mating. Spiny waterflea Where did the spiny waterflea come from? Certain fish might be the next step to ending the spiny water flea problem. The spiny water flea (Bythotrephes cederstroemi) is a non-native species of cladocera that has become quite common in the Great Lakes.These were first discovered in Lake Huron in 1984, and have since spread to the other lakes. Spiny waterflea introductions result in an average 30 to 40 per cent decline in native populations of zooplankton. The invader came from the Caspian Sea in Asia and spread throughout Europe, said Steve Carpenter, co-author of the study and director of the Center for Limnology at the University of Wisconsin-Madison. of Conservation and Recreation.
