2011 Project Abstract For the Period Ending June 30, 2014 PROJECT TITLE: Mississippi River Water Quality Assessment PROJECT MANAGER: Michael Sadowsky AFFILIATION: University of Minnesota MAILING ADDRESS: 140 Gortner Lab, 1479 Gortner Ave CITY/STATE/ZIP: Saint Paul, MN 55108 PHONE: (612) 626-0977 E-MAIL: [email protected] WEBSITE: http://www.cbs.umn.edu/main/news/inthefield/m3p.shtml FUNDING SOURCE: Environment and Natural Resources Trust Fund LEGAL CITATION: M.L. 2011, First Special Session, Chp. 2, Art.3, Sec. 2, Subd. 05c APPROPRIATION AMOUNT: $ 557,000 Overall Project Outcome and Results A metagenomics-based sequencing approach was utilized to characterize the bacterial community at sites along the Mississippi River in Minnesota to understand how these communities were influenced by or indicative of water quality. Results of this study revealed that the bacterial community throughout the river primarily consisted of a small number of highly abundant species that comprise a “core microbial community” that was stable both in terms of community membership and inferred functional traits. Variation in community membership and species abundances were primarily influenced by physicochemical parameters (e.g. pH and temperature) rather than spatial distance, and a reproducible community structure occurred annually toward the late summer. Furthermore, specific bacterial orders were related to chemical concentrations that co-varied with surrounding land use, suggesting that increases in abundance of these orders may be indicative of specific types of contamination throughout the river. Therefore, assessment of the total bacterial community provides more information about water quality and contamination sources than could be previously gleaned from traditional enumeration of indicator bacteria like Escherichia coli. -
Using Stable Isotopes to Investigate Movement of Fish in Rice Paddy Fields
Int Aquat Res DOI 10.1007/s40071-015-0105-y ORIGINAL RESEARCH Using stable isotopes to investigate movement of fish in rice paddy fields Jaeyong Lee . Jae-Ok Kim . Jeffrey S. Owen . Bomchul Kim Received: 7 January 2015 / Accepted: 17 April 2015 Ó The Author(s) 2015. This article is published with open access at Springerlink.com Abstract We evaluated movement of fish, especially Misgurnus spp. (loach), in paddy fields and irrigation ponds by conducting an inventory of d13C and d15N of fish, potential food sources, and soil organic matter in two irrigation pond–paddy field systems in Korea. The pond–paddy systems differ with respect to the presence or the absence of a ridge between the paddy field and the irrigation pond and also whether or not livestock are present in their watersheds. The ridge prevents the free movement of fish between paddy field and irrigation pond habitats in one of the pond–paddy watersheds, but not in the other watershed. We found differences in loach d13C and d15N inhabiting the paddy fields compared to those in loach d13C and d15Nin the irrigation ponds. In irrigation ponds, loach d13C was lower in September (average -27.9 and -27.7 %) compared to July (average -26.2 and -26.3 %) in the watershed with a ridge (station 1) and without a ridge (station 6), respectively. Loach d13C in irrigation ponds in September was similar to loach d13C in the paddy field in July at both sampling sites, indicating loach might have moved into irrigation pond from paddy field. Loach d15N in the watershed with livestock was significantly higher (average 18.2 %) in the irrigation ponds than loach d15N in the watershed with no livestock present (average 11.3 %), probably reflecting higher anthropogenic nitrogen inputs from livestock. -
A Case Study of Weatherfish (Misgurnus Fossilis)
www.nature.com/scientificreports OPEN The role of detritivory as a feeding tactic in a harsh environment – a case study of weatherfsh Received: 31 July 2018 Accepted: 28 May 2019 (Misgurnus fossilis) Published: xx xx xxxx Kacper Pyrzanowski 1, Grzegorz Zięba 1, Małgorzata Dukowska1, Carl Smith1,2,3 & Mirosław Przybylski1 The weatherfsh (Misgurnus fossilis) is a species that is tolerant of unfavourable environmental conditions and can survive low dissolved oxygen concentrations and high water temperatures. Although this species occurs across almost the whole of Europe, and is protected in many countries, relatively little is known regarding its ecology. To determine the diet of weatherfsh, 120 individuals from an artifcial drainage canal in central Poland were collected in two seasons (spring and late summer) with contrasting abiotic condition (oxygen concentration, water temperature and transparency). Analysis of gut fullness showed that weatherfsh consumed a greater quantity of food in spring (0.92 ± 0.90) compared with summer (0.20 ± 0.26). Contrary to other cobitid taxa, weatherfsh fed actively during daytime in both seasons. An estimate of the importance of each dietary component indicated that the most important food categories were chironomids, copepods, Asellus aquaticus and detritus. SIMPER analysis indicated that these four categories together constituted over 65.8% of cumulative dissimilarity in the diet between seasons. Additionally, trophic niche breadth difered signifcantly between seasons. The study demonstrated that the weatherfsh is an opportunistic feeder, consuming large quantities of detritus despite possessing a gut morphology that is atypical of a detritivore. The quantity of detritus in the gut of weatherfsh was positively associated with fsh total length and varied seasonally, with a greater quantity of detritus in the diet in late summer. -

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. -

Checklist of the Inland Fishes of Louisiana Abstract Since the publication of Freshwater Fishes of Louisiana (Douglas, 1974) and a revised checklist (Douglas and Jordan, 2002), much has changed regarding knowledge of inland fishes in the state. An updated reference on Louisiana’s inland and coastal fishes is long overdue. Inland waters of Louisiana are home to at least 224 species (165 primarily freshwater, 28 primarily marine, and 31 euryhaline or diadromous) in 45 families. This checklist is based on a compilation of fish collections records in Louisiana from 19 data providers in the Fishnet2 network (www.fishnet2.net). -
(Percidae) Is the Valid Generic Name for Walleye, Sauger, and Eurasian
ESSAY Stizostedion Rafinesque, 1820 (Percidae) is the Valid Generic Name for Walleye, Sauger, and Eurasian Pikeperch John Clay Bruner | University of Alberta, Department of Biological Sciences, 116 St & 85 Ave, Edmonton, Alberta T6G 2E9, Canada. E-mail: [email protected] Theodore Nicholas Gill’s misconception of Lorenz Okenfuss’s use of the Latvian vernacular name Sander for Cuvier’s French vernacular name Les Sandres, as a properly coined Latin name, led to Gill’s and subsequent authors’ incorrect acceptance of Sander as the senior synonym for Stizostedion. However, some authors, aware Sander is a common name and never proposed as a valid generic name, have continued using the correct generic name Stizostedion. American Fisheries Society guidelines for pub- lication in their journals and the Canadian Journal of Fisheries and Aquatic Sciences requires authors to use the current edition of Common and Scientific Names of Fishes from the United States, Canada, and Mexico, which has incorrectly used Sander in the last two editions. Thus, fishery biologists have been forced to use an incorrect generic name for one of the most important freshwater fisheries of North America. Stability of zoological nomenclature will never be at- are found possessing the same distinctions, in which tained as long as authors exercise indiscriminately their case my two perches may then be called Stizostedion privilege of introducing into the literature any name salmoneum, and Lepibema chrysops. that suits their fancy or convenience.
