Iowa Darter Etheostoma Exile ILLINOIS RANGE

Iowa darter Etheostoma exile Kingdom: Animalia FEATURES Phylum: Chordata The Iowa darter averages about two and three- Class: Osteichthyes fourths inches in length. It is a brown or green- Order: Perciformes brown fish with eight to 10 dark marks on the back and 10 to 14 dark blotches on the side separated by Family: Percidae red spaces. There is a dark, teardrop mark under the ILLINOIS STATUS eye and a dark bar in front of the eye, as well as bars on the fins. The lateral line is short, extending to common, native about the second dorsal fin. There are two spines in the anal fin. The cheeks have scales. The breeding male has a blue tint to the back, green side blotches separated by rust-red spaces, wide bands of blue and orange in the first dorsal fin and orange along the lower sides. BEHAVIORS The Iowa darter may be found in glacial lakes in northeastern Illinois, a few streams in northern Illinois and a few limestone quarries in Vermilion County. It lives in clear lakes, sloughs and creeks that have many aquatic plants. In streams it can be found in quiet pools over a mud or clay bottom with dead material and brush. Spawning occurs in April in shallow water over roots, vegetation or debris. The young Iowa darter eats plankton, while the adult feeds on immature insects and small crustaceans.

AN ANALYSIS of SEXUAL DIMORPHISM in LENGTH and WEIGHT RELATIONSHIPS of IOWA DARTERS Margaret a Harings Northland College, CB: 853 1411 Ellis Ave Ashland, WI 54806
AN ANALYSIS OF SEXUAL DIMORPHISM IN LENGTH AND WEIGHT RELATIONSHIPS OF IOWA DARTERS Margaret A Harings Northland College, CB: 853 1411 Ellis Ave Ashland, WI 54806 ABSTRACT Iowa darters, Etheostoma exile, are commonly found throughout the Lake Superior watershed. However, given their abundance and non-game status, little is known about basic life history characteristics of these fish. Iowa darters were seined from Inch Lake (Bayfield County, WI) in May of 2010 and 2011 to assess sexual dimorphism in sizes. Collected fish were immediately frozen and later thawed and measured for total length (TL) and total weight (TW), and dissected to remove the gonads which were also weighed. Somatic weight (SW) was calculated for each fish. The mean TL of males and females did not differ. There was a weak difference in the relationships between log(TW) and log(TL) between male and female Iowa darters. There was a strong difference in the relationships between the log(GW) and log(TL) for males and females. However, a significant difference did not exist between log(somatic weight) and log(TL) between males and females. The weak difference in the TL-TW relationship between males and females appear to be due to the strong difference in the TL-GW relationship between the sexes. Additional research is planned to determine whether differences between males and females occur in age structure and diet. INTRODUCTION Iowa darters are small fish that are typically found in clear to slightly turbid, light brown water of small lakes, bogs, and small streams (Becker 1983). The range of Iowa darters extends east to New York, west to Montana, north to southern Canada, and south to portions of Illinois (Scott and Crossman 1973; Lee and Gilbert 1978).

Hatch Dept. of Postsecondary Teaching and Learning and James Ford Bell Museum of Natural History, University of Minnesota James D. Johnson Earth Science Department, St. Francis High School, St. Francis, MN in Canada and among the seven most widespread darter species in the United States. The Great Northerner also is highly variable in terms of its body shape and color. In Minnesota alone, males looking for mates might wear any one of at least three distinctly different colored suits (see page 11). Even its collection of genes is odd enough to make it hard to say who its closest relatives are. Finally, it is one of eight darter species known to inhabit lakes as well as streams. So, it is a bit surprising that only two popula- tions have been the subjects of detailed life history studies, one in Nebraska (Evans 1974) and one in Wyoming (Copes 1976, published in our very own American Currents). Vari- ous bits of information on about 17 additional populations scattered from Colorado to Ontario appear in a variety of published and unpublished works. In Minnesota, the Iowa Darter is one of our most com- mon and widespread fish species. It occurs in every major basin of the state, although it occurs less frequently in areas of intensive row-cropping (Figure 1). We became interested in this species back in the 1980s while studying the larval fishes of Lake Itasca, the official but incorrect headwaters of the mighty Mississippi River.

COSSARO Candidate Species at Risk Evaluation for Round Hickorynut, Obovaria Subrotunda
COSSARO Candidate Species at Risk Evaluation for Round Hickorynut, Obovaria subrotunda Committee on the Status of Species at Risk in Ontario (COSSARO) Assessed by COSSARO as Endangered Obovarie ronde (Obovaria subrotunda) L’obovarie ronde est une espèce de moule d’eau douce brun foncé qui tient son nom de sa forme arrondie. Les adultes sont relativement petits, atteignant une longueur d’environ 6 cm, et vivent attachés à des substrats de gravier et de sable dans les rivières et les zones de delta de lac peu profondes. Les adultes préfèrent un débit d’eau moyen pour leur permettre de filtrer les algues et les bactéries avec leurs branchies. Tout comme les autres espèces de moules d’eau douce, les larves vivent en parasite sur un poisson-hôte pendant une partie de leur développement. L’obovarie ronde se trouvait historiquement dans 12 États et dans la province de l’Ontario. La plupart des populations américaines sont en déclin et l’espèce est récemment disparue de deux États. L’obovarie ronde est disparue d’environ 90 % de son aire de répartition historique au Canada. Les populations des rivières Grand et Thames en Ontario sont disparues et la population de la rivière Sydenham est probablement près de disparaître. La menace la plus importante qui pèse sur les populations d’obovarie ronde est la moule zébrée, qui colonise les substrats et supplante les moules indigènes. La seule population importante de l’espèce qui reste au Canada se trouve dans une zone peu profonde du lac Ste-Claire près de l’île Walpole, bien qu’on ignore si cette population continue de se reproduire avec succès.

Fish: Darters
FISH: DARTERS Since the late 1800s, there have been 104 different species of fishes found in the Minnesota River Basin. Over the past years, 12 of those species have not been seen for over 30 years and are believed to be extirpated (Schmidt and Proulx, 2007). The fishes live in a variety of habitats which include, “shallow lakes and low-gradient streams on the uplands flanking the Minnesota River valley, high-gradient streams where tributaries to the river descend into the valley, and the winding main stem of the Minnesota and floodplain lakes on the valley floor”(Schmidt and Proulx, 2007). Some fish biologists use Darters as indicators of water quality. The presence or absence of some species can tell experts about water quality. Historically 10 different species of Darters have been found in the Minnesota River Basin, but over the past few years, only 6 have been documented. The Crystal Darter has not been found since the 1960s, while the Johnny Darter is quite abundant. All Darters are about finger length or 2-3 inches.

Minnesota Fish Taxonomic Key 2017 Edition
Minnesota Fish Taxonomic Key 2017 Edition Pictures from – NANFA (2017) Warren Lamb Aquatic Biology Program Bemidji State University Bemidji, MN 56601 Introduction Minnesota’s landscape is maze of lakes and river that are home to a recorded total of 163 species of fish. This document is a complete and current dichotomous taxonomic key of the Minnesota fishes. This key was based on the 1972 “Northern Fishes” key (Eddy 1972), and updated based on Dr. Jay Hatch’s article “Minnesota Fishes: Just How Many Are There?” (Hatch 2016). Any new species or family additions were also referenced to the 7th edition of the American Fisheries society “Names of North American Fishes” (Page et al. 2013) to assess whether a fish species is currently recognized by the scientific community. Identifying characteristics for new additions were compared to those found in Page and Burr (2011). In total five species and one family have been added to the taxonomic key, while three have been removed since the last publication. Species pictures within the keys have been provide from either Bemidji State University Ichthyology Students or North American Native Fish Association (NANFA). My hope is that this document will offer an accurate and simple key so anyone can identify the fish they may encounter in Minnesota.

Patternsof life-history diversification in North American fishes: impli- cations for population regulation. Can.). Fish. Aquat. Sci. 49: 2196-2218. Interspecific patterns of fish life histories were evaluated in relation to several theoretical models of life-history evolution. Data were gathered for 216 North American fish species(57 families) to explore relationships among variables and to ordinate species. Multivariate tests, performed on freshwater, marine, and combined data ma- trices, repeatedly identified a gradient associating later-maturing fishes with higher fecundity, small eggs, and few bouts of reproduction during a short spawning seasonand the opposite suite of traits with small fishes. A second strong gradient indicated positive associationsbetween parental care, egg size, and extended breeding seasons.Phylogeny affected each variable, and some higher taxonomic groupings were associatedwith particular life-history strategies. High-fecundity characteristics tended to be associated with large species ranges in the marine environment. Age at maturation, adult growth rate, life span, and egg size positively correlated with anadromy. Parental care was inversely correlated with median latitude. A trilateral continuum basedon essential trade-offs among three demographic variables predicts many of the correlations among life-history traits.

Wadley Lake the Fishery Wadley Lake Supports a Warm Water Fish Community. in 2012, Eleven Fish Species Were Sampled and Identi
Wadley Lake The Fishery Wadley Lake supports a warm water fish community. In 2012, eleven fish species were sampled and identified out of the sixteen total species that have been recorded in surveys dating back to 1967 that were obtained from the Wisconsin DNR (WDNR) (Table X). Although most species identified in 2012 have been previously reported, the bluntnose minnow (Pimephales notatus), Iowa darter (Etheostoma exile), and yellow bullhead (Ameiurus natalis) were newly documented. Species documented previously but not detected during the 2012 survey include brown bullhead (Ameiurus nebulosus), emerald shiner (Notropis atherinoides), Johnny darter (Etheostoma nigrum), central mudminnow (Umbra lima), and pumpkinseed (Lepomis gibbosus). Bluegill (Lepomis macrochirus) were most abundant during both the fyke netting and shocking surveys in 2012. Bluegill reached a maximum size of 8.3 inches (Table Y and Table Z). Green sunfish (Lepomis cyanellus), which are relatively uncommon to this area, were also present in the lake. Although infrequently encountered, walleye (Sander vitreus) reaching 22.3 inches were caught. Yellow perch (Perca flavecens) and northern pike (Esox lucius) were not frequently found during 2012 sampling. Three rusty crayfish (Orconectes rusticus) were captured during the sampling period. Table X: Species occurrence in Wadley Lake in the 2012 survey and historical Wisconsin DNR records.
