Gravel Chub Erimystax X-Punctatus Adult ILLINOIS RANGE

gravel chub Erimystax x-punctatus Kingdom: Animalia FEATURES Phylum: Chordata The gravel chub is a slender fish with an average Class: Osteichthyes length of two and one-half to three and one-half Order: Cypriniformes inches. The "X"-shaped marks on the back and sides are distinctive. A small, cone-shaped barbel Family: Cyprinidae (whiskerlike projection) is present at each corner of ILLINOIS STATUS the mouth. The snout extends beyond the upper lip. The back is green-yellow with a dusky stripe in the threatened, native center while the sides are silvery, sometimes with a © William N. Roston faint stripe. A small, black spot is often present at the base of the tail. The breeding male is covered with tubercles (bumps) on the head and front portion of the body. BEHAVIORS The gravel chub lives in streams that are clear or with moderate turbidity, permanent flow and a gravel bottom. The gravel chub lives on or near the bottom of the stream, resting behind or under rocks. It spawns in early spring in gravel riffles. This fish is adult an omnivore, feeding on both plant and animal materials it finds in crevices on the bottom. ILLINOIS RANGE © Illinois Department of Natural Resources. 2020.

Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa
Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa By Jun Cheng A thesis submitted in conformity with the requirements for the degree of Masters of Science Ecology and Evolutionary Biology University of Toronto © Copyright Jun Cheng 2013 Spatial Criteria Used in IUCN Assessment Overestimate Area of Occupancy for Freshwater Taxa Jun Cheng Masters of Science Ecology and Evolutionary Biology University of Toronto 2013 Abstract Area of Occupancy (AO) is a frequently used indicator to assess and inform designation of conservation status to wildlife species by the International Union for Conservation of Nature (IUCN). The applicability of the current grid-based AO measurement on freshwater organisms has been questioned due to the restricted dimensionality of freshwater habitats. I investigated the extent to which AO influenced conservation status for freshwater taxa at a national level in Canada. I then used distribution data of 20 imperiled freshwater fish species of southwestern Ontario to (1) demonstrate biases produced by grid-based AO and (2) develop a biologically relevant AO index. My results showed grid-based AOs were sensitive to spatial scale, grid cell positioning, and number of records, and were subject to inconsistent decision making. Use of the biologically relevant AO changed conservation status for four freshwater fish species and may have important implications on the subsequent conservation practices. ii Acknowledgments I would like to thank many people who have supported and helped me with the production of this Master’s thesis. First is to my supervisor, Dr. Donald Jackson, who was the person that inspired me to study aquatic ecology and conservation biology in the first place, despite my background in environmental toxicology.

2000, No. 1COPEIA February 1 Copeia, 2000(1), pp. 1±10 Phylogenetic Relationships in the North American Cyprinid Genus Cyprinella (Actinopterygii: Cyprinidae) Based on Sequences of the Mitochondrial ND2 and ND4L Genes RICHARD E. BROUGHTON AND JOHN R. GOLD Shiners of the cyprinid genus Cyprinella are abundant and broadly distributed in eastern and central North America. Thirty species are currently placed in the genus: these include six species restricted to Mexico and three barbeled forms formerly placed in different cyprinid genera (primarily Hybopsis). We conducted a molecular phylogenetic analysis of all species of Cyprinella found in the United States, using complete nucleotide sequences of the mitochondrial, protein-coding genes ND2 and ND4L. Maximum-parsimony analysis recovered a single most-parsimonious tree for Cyprinella. Among historically recognized, nonbarbeled Cyprinella, the mitochondrial (mt) DNA tree indicated that basal lineages in Cyprinella are comprised largely of species with linear breeding tubercles and that are endemic to Atlantic and/or Gulf slope drainages, whereas derived lineages are comprised of species broadly distrib- uted in the Mississippi basin and the American Southwest. The Alabama Shiner, C. callistia, was basal in the mtDNA tree, although a monophyletic Cyprinella that in- cluded C. callistia was not supported in more than 50% of bootstrap replicates. There was strong bootstrap support (89%) for a clade that included all species of nonbarbeled Cyprinella (except C. callistia) and two barbeled species, C. labrosa and C. zanema. The third barbeled species, C. monacha, fell outside of Cyprinella sister to a species of Hybopsis. Within Cyprinella were a series of well-supported species groups, although in some cases bootstrap support for relationships among groups was below 50%.

OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN ANNARBOR, MICHIGAN PRELIMINARY ANALYSIS OF THE AMERICAN CYPRINID FISHES, SEVEN NEW, REFERRED TO THE GENUS HYBOPSIS, SUBGENUS ERIlWYSTAX* BY CARLL. HUBBSAND WALTERR. CROWE FORmany years we have studied the eastern North American cyprinid fishes that were recently referred to the genus Erimystax Jordan. Earlier, this assortment of species had been included in the genus Hybopsis. In the present swing of the pendulum these species are again placed in Hybopsis, though they may be retained in Erimystax as a subgenus. For several reasons the re-expanded genus Hybopsis rests on an un- steady basis, but it is not our purpose to attempt a generic evaluation. The differential diagnoses to follow are presented in analytical form. The rubrics in the key that pertain to each form may be visualized in the outline of classification that heads the analysis. Thus, for Hybopsis insignis eristigma it will be at once apparent that the diagnosis com- prises items Ib, 3b, 4b, 5b, 7b, and 9b. In addition, the diagnosis of each form may be taken to include the following features of Erimystax, common to all: A single small barbel is developed in the ternlinal or nearly terminal position (over or behind the end of the gape). The scales lack basal radii. The hooked pharyngeal teeth are uniserial, and number four on each side. The nuptial tubercles are minute or even obsolete on the top of the head (never enlarged as in Nocomis). The species are all small (none longer than 100 mm. to caudal) and delicate.

Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86
2009. Proceedings of the Indiana Academy of Science 1 1 8(2): 143—1 86 THE "LOST" JORDAN AND HAY FISH COLLECTION AT BUTLER UNIVERSITY Carter R. Gilbert: Florida Museum of Natural History, University of Florida, Gainesville, Florida 32611 USA ABSTRACT. A large fish collection, preserved in ethanol and assembled by Drs. David S. Jordan and Oliver P. Hay between 1875 and 1892, had been stored for over a century in the biology building at Butler University. The collection was of historical importance since it contained some of the earliest fish material ever recorded from the states of South Carolina, Georgia, Mississippi and Kansas, and also included types of many new species collected during the course of this work. In addition to material collected by Jordan and Hay, the collection also included specimens received by Butler University during the early 1880s from the Smithsonian Institution, in exchange for material (including many types) sent to that institution. Many ichthyologists had assumed that Jordan, upon his departure from Butler in 1879. had taken the collection. essentially intact, to Indiana University, where soon thereafter (in July 1883) it was destroyed by fire. The present study confirms that most of the collection was probably transferred to Indiana, but that significant parts of it remained at Butler. The most important results of this study are: a) analysis of the size and content of the existing Butler fish collection; b) discovery of four specimens of Micropterus coosae in the Saluda River collection, since the species had long been thought to have been introduced into that river; and c) the conclusion that none of Jordan's 1878 southeastern collections apparently remain and were probably taken intact to Indiana University, where they were lost in the 1883 fire.

Thomas Fisheries Program Coordinator 2011 (Third edition, 2021) Kentucky Department of Fish & Wildlife Resources Division of Fisheries Cover paintings by Rick Hill • Publication design by Adrienne Yancy Preface entucky is home to a total of 245 native fish species with an additional 24 that have been introduced either intentionally (i.e., for sport) or accidentally. Within Kthe United States, Kentucky’s native freshwater fish diversity is exceeded only by Alabama and Tennessee. This high diversity of native fishes corresponds to an abun- dance of water bodies and wide variety of aquatic habitats across the state – from swift upland streams to large sluggish rivers, oxbow lakes, and wetlands. Approximately 25 species are most frequently caught by anglers either for sport or food. Many of these species occur in streams and rivers statewide, while several are routinely stocked in public and private water bodies across the state, especially ponds and reservoirs. The largest proportion of Kentucky’s fish fauna (80%) includes darters, minnows, suckers, madtoms, smaller sunfishes, and other groups (e.g., lam- preys) that are rarely seen by most people.

ACTION: Original DATE: 12/28/2011 8:06 AM 3745-1-01 Purpose and applicability. [Comment: For dates of non-regulatory government publications, publications of recognized organizations and associations, federal rules and federal statutory provisions referenced in this rule, see rule 3745-1-03 of the Administrative Code.] (A) Purpose and objective. It is the purpose of this chapter to: (1) Establish minimum water quality requirements for all surface waters of the state, thereby protecting public health and welfare; (2) Enable the present and planned uses of Ohio's water for public water supplies, industrial and agricultural needs, propagation of fish, aquatic life and wildlife, and recreational purposes; (3) Enhance, improve and maintain water quality as provided under the laws of the state of Ohio, section 6111.041 of the Revised Code, the federal Clean Water Act, 33 U.S.C. sections 1251 to 1387, and rules adopted thereunder; and (4) Further the overall objective of the Clean Water Act "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters." (B) Goals. Consistent with national goals set forth in the Clean Water Act, all surface waters in Ohio shall provide for the protection and propagation of fish, shellfish, and wildlife and provide for recreation in and on the water unless the director determines the goal is not attainable for a specific water body. If the director determines that a water body cannot reasonably attain these goals using the available tests and criteria allowed under the Clean Water Act, then one of the following steps shall be taken: (1) The director shall evaluate the water body's designated uses and, where uses are not attainable, propose to change the designated uses to the best designations that can be attained; or (2) The director shall grant temporary variances from compliance with one or more water quality criteria applicable by this chapter pursuant to rule 3745-33-07 of the Administrative Code.
