The Lake Michigan Natural Division Characteristics
The Lake Michigan Natural Division Characteristics Lake Michigan is a dynamic deepwater oligotrophic ecosystem that supports a diverse mix of native and non-native species. Although the watershed, wetlands, and tributaries that drain into the open waters are comprised of a wide variety of habitat types critical to supporting its diverse biological community this section will focus on the open water component of this system. Watershed, wetland, and tributaries issues will be addressed in the Northeastern Morainal Natural Division section. Species diversity, as well as their abundance and distribution, are influenced by a combination of biotic and abiotic factors that define a variety of open water habitat types. Key abiotic factors are depth, temperature, currents, and substrate. Biotic activities, such as increased water clarity associated with zebra mussel filtering activity, also are critical components. Nearshore areas support a diverse fish fauna in which yellow perch, rockbass and smallmouth bass are the more commonly found species in Illinois waters. Largemouth bass, rockbass, and yellow perch are commonly found within boat harbors. A predator-prey complex consisting of five salmonid species and primarily alewives populate the pelagic zone while bloater chubs, sculpin species, and burbot populate the deepwater benthic zone. Challenges Invasive species, substrate loss, and changes in current flow patterns are factors that affect open water habitat. Construction of revetments, groins, and landfills has significantly altered the Illinois shoreline resulting in an immeasurable loss of spawning and nursery habitat. Sea lampreys and alewives were significant factors leading to the demise of lake trout and other native species by the early 1960s. -

Introductions also occur through escaped or discarded live bait. It has become a threat to the Great Lakes in North America and some lakes in Europe. Gymnocephalus cernuus has become invasive due to its reproduction ablity; its wide habitat range and its aggressive feeding habits. view this species on IUCN Red List Species Description Gymnocephalus cernuus are small, reaching up to 20cm in length, with olive brown colouring on the back and pale sides. They have spiny dorsal and anal fins (Hajjar, 2002). Notes According to Hajjar (2002), \"Gymnocephalus cernuus have few predators in Europe and Asia, and most will only prey on G. cernuus when other prey is scarce. Predators include pike perch, northern pike, some eel, burbot, lake trout, small-mouth bass, black crappie, bullheads, walleye, Eurasian perch, yellow perch, cormorants, and kingfishers. To avoid predators, the ruffe prefers darkness, and uses special sensory organs called \"neuromasts\" to detect predators and prey. The ruffe also has a large, spiny dorsal fin likely unpalatable to predators. Global Invasive Species Database (GISD) 2021. Species profile Gymnocephalus Pag. 1 cernuus.

ACTA ICHTHYOLOGICA ET PISCATORIA Vol. XXXII, Fasc. 2 2002 ON THE ROLE OF PARATENIC HOSTS IN THE LIFE CYCLE OF THE NEMATODE ANGUILLICOLA CRASSUS IN THE VISTULA LAGOON, POLAND Leszek ROLBIECKI* Division of Invertebrate Zoology, University of Gdaƒsk, Poland Rolbiecki L., 2002. On the role of paratenic hosts in the life cycle of the nematode Anguillicola crassus in the Vistula Lagoon, Poland. Acta Ichthyol. Piscat. 32 (2): 109–116. Anguillicola crassus is an Asian nematode accidentally introduced to Europe and parasitising the swim bladder of European eels. Planktonic copepods are the major intermediate hosts but the success of this parasites depends on small fishes, acting as paratenic hosts and transmitting the nematode to eels. The role played by cyprinids and percids in the life cycle of A. crassus in the Vistula Lagoon was analysed. A total of 2398 fish specimens (1091 percids and 1307 cyprinids) were examined within December 1994–March 1997. The presence of the nematode was recorded in zander (Sander lucioperca), European perch (Perca fluviatilis), ruffe (Gymnocephalus cernuus), carp bream (Abramis brama), ziege (Pelecus cultratus), and roach (Rutilus rutilus), the ruffe being the most heavily infected fish species. The present findings advance our knowledge on the biology A. crassus and will help to predict its spread to other bodies of water. Key words: parasite, fish, Anguillicola crassus, eel, Anguilla anguilla, paratenic host, Gymnocephalus cernuus, Poland, Vistula Lagoon INTRODUCTION Nematodes of the genus Anguillicola parasitise the swim bladder of eel. Among the five Anguillicola species described so far, two (Anguillicola crassus Kuwahara Niimi et Itagaki, 1974 and Anguillicola novaezelandiae Moravec et Taraschewski, 1988) have been found in Europe. -

(2014): “The ruffe was first identified by Wisconsin DNR in specimens collected from the St. Louis River at the border of Minnesota and Wisconsin in 1987 (Pratt 1988; Pratt et al. 1992; Czypinski et al. 1999, 2000, 2001, 2003). Following that report, reexamination of archived samples revealed misidentified larval specimens of ruffe had been collected from the same area in 1986 (Pratt 1988). The ruffe subsequently spread into Duluth Harbor in Lake Superior and several tributaries of the lake (Underhill 1989; Czypinski et al. 1999, 2000, 2004; Scheidegger, pers. comm.; J. Slade, pers. comm.). It is found in the Amnicon, Flag, Iron, Middle, Raspberry, and Bad rivers, Chequamegon Bay, and Apostle Islands National Lakeshore in Wisconsin (Czypinski et al. 1999, 2000, 2001, 2003, 2004; Tilmant 1999). In August 1994, it was found in Saxon Harbor, Wisconsin, and in the upper peninsula of Michigan at the mouths of the Black and Ontonagon rivers (K. Kindt, pers. comm.). In the lower Peninsula of Michigan along Lake Huron, the first three specimens were caught at the mouth of the Thunder Bay River in August 1995 (K. Kindt, pers. comm.). This species has also been collected in Michigan in Lake Michigan, Lake Superior, Torch Lake, Little Bay de Noc in Escanaba, Big Bay de Noc, Misery River, Ontonagon River, Thunder Bay, and Sturgeon River Sloughs (Czypinski et al. -

A Synopsis of the Biology and Life History of Ruffe
J. Great Lakes Res. 24(2): 170-1 85 Internat. Assoc. Great Lakes Res., 1998 A Synopsis of the Biology and Life History of Ruffe Derek H. Ogle* Northland College Mathematics Department Ashland, Wisconsin 54806 ABSTRACT. The ruffe (Gymnocephalus cernuus), a Percid native to Europe and Asia, has recently been introduced in North America and new areas of Europe. A synopsis of the biology and life history of ruffe suggests a great deal of variability exists in these traits. Morphological characters vary across large geographical scales, within certain water bodies, and between sexes. Ruffe can tolerate a wide variety of conditions including fresh and brackish waters, lacustrine and lotic systems, depths of 0.25 to 85 m, montane and submontane areas, and oligotrophic to eutrophic waters. Age and size at maturity dif- fer according to temperature and levels of mortality. Ruffe spawn on a variety ofsubstrates, for extended periods of time. In some populations, individual ruffe may spawn more than once per year. Growth of ruffe is affected by sex, morphotype, water type, intraspecific density, and food supply. Ruffe feed on a wide variety of foods, although adult ruffe feed predominantly on chironomid larvae. Interactions (i.e., competition and predation) with other species appear to vary considerably between system. INDEX WORDS: Ruffe, review, taxonomy, reproduction, diet, parasite, predation.
