FULLING Gulf Coast Research Laboratory, Institute of Marine Sciences, The University of Southern Mississippi, 703 East Beach Drive, Ocean Springs, Mississippi 39564, USA Abstract.ÐCycleptus meridionalis is a new species recently distinguished from blue sucker C. elongatus. It occurs in large rivers draining to the northern Gulf of Mexico chie¯y through Alabama and Mississippi. Collections over a 12-month period from the Pearl and Pascagoula rivers, Mis- sissippi, were taken to document the new species' life history characteristics. Female C. meri- dionalis had signi®cantly greater wet weight (WW, kg) per given total length (TL, mm) (WW 5 4.228213 TL4.588) than males (WW 5 2.00029 TL3.237). Aged opercular bones indicated that one annulus formed during September±October at the beginning of the reproductive season. Fish ages in the sample ranged from 6 to 31 years for females and from 4 to 33 years for males. Longevity of C. meridionalis is markedly greater than previous scale aging of C. elongatus had suggested. Male C. meridionalis as small as 327 mm TL (age 4) and females as small as 444 mm TL (age 11) had visibly developed gonads; mean gonadosomatic index was elevated in both sexes between October and March and declined by early April. Spawning began in February to early March when the temperature exceeded 13±148C. The sex ratio was not different from 1:1 (P . 0.05). Cycleptus meridionalis foraged on aquatic insect larval stages; trichopteran larvae and pupae, chironomid larvae and pupae, and coleopteran larvae were the most common prey items regardless of sex, size, or river. These life history characteristics and food habits are similar to those reported for C. elongatus in the Mississippi River drainage. Our observations indicate that C. meridionalis is viable in both rivers sampled but may be in¯uenced by future river modi®cation as has happened with C. elongatus, which is threatened or endangered over much of its range.

Dyer and William J. Poly Department of Zoology Southern Illinois University Carbondale, Illinois 62901-6501 ABSTRACT Rhabdochona cascadilla was detected in the intestine of Cycleptus elongatus from the Mississippi River in Randolph County, Illinois. This constitutes the first record of this rhabdochonid nematode in the blue sucker and the only internal helminth for this host. INTRODUCTION Nematodes of the genus Rhabdochona Railliet, 1916 (Thelazioidea, Rhabdochonidae) are cosmopolitan in distribution as intestinal parasites of freshwater fishes (Moravec and Coy Otero, 1987; Moravec, 1994). Approximately 96 nominal species have been recognized of which 19 have been reported from North and South America (see Sanchez-Alvarez et al., 1998). Of rhabdochonid nematodes reported from North America, Rhabdochona cascadilla Wigdor, 1918 has been recorded in 13 families, 30 genera, and 53 species of freshwater fishes across Canada and the United States (Hoffman, 1999). Identification of Rhabdochona species is difficult as many of them have been inadequately or erroneously described, and as pointed out by Sanchez-Alvarez et al. (1998), a detailed taxonomic revision of all putative species in this group warrants initiation. MATERIALS AND METHODS A single adult female blue sucker (557 mm standard length) was collected incidentally by electrofishing on 24 October 1996 from the Mississippi River just below the mouth of the Kaskaskia River, Randolph County, Illinois and was transported alive to the laboratory.

    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

MAKINSTER* Division of Biology, Kansas State University, Manhattan, KS, USA C. P. PAUKERT U.S. Geological Survey, Kansas Cooperative Fish and Wildlife Research Unit, Division of Biology, Kansas State University, Manhattan, KS, USA Abstract Blue sucker, Cycleptus elongatus (Le Sueur), was sampled in the Kansas River, Kansas, USA to determine how relative abundance varies spatially and growth compares to other populations. Electric fishing was conducted at 36 fixed sites during five time periods from March 2005 to January 2006 to determine seasonal distribution. An additional 302 sites were sampled in summer 2005 to determine distribution throughout the river. A total of 101 blue sucker was collected ranging from 242 to 782 mm total length and 1–16 years old. Higher catch rates were observed in upper river segments and below a low-head dam in lower river segments, and catch rates were higher during November in the upriver sites. Kansas River blue sucker exhibited slower growth rates than other populations in the Great Plains including populations as far north as South Dakota.

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.

Mayden Abstract The order Cypriniformes and family Catostomidae, the Holarctic suckers, have received considerable phylogenetic attention in recent years. These studies have provided contrasting phylogenies and classifications to historical, morphology-based phylogenetic and prephylogenetic hypotheses of relationships of species and the naturalness of hypothesized genera, tribes, and subfamilies. To date, nearly all molecular work on catostomids has been done using DNA sequence variation of mitochondrial genes. In this study, we add to our previous investigations to identify single-copy nuclear gene markers for diploid and polyploid cypriniforms, and to expand sequences of nuclear IRBP2 gene to 1,933 bp for 23 catostomid species. This effort expands our previous studies using only partial sequences of 849 bp. The extended gene fragment consists of nearly the complete gene across exon1 to exon 4 and is used in two analyses to infer phylogenetic relationships of the currently, or formerly, recognized genera, tribes, and subfamilies. One analysis includes 23 ingroup species for which the larger fragment of IRBP2 could be obtained; these taxa were also included in a second analysis of 67 samples of 52 species for the shorter fragment.

  • A Distributional Checklist of the Fishes of Kentucky
    A Distributional Checklist of the Fishes of Kentucky BROOKS M. BURR Department of Zoology, Southern Illinois University, Carbondale, Illinois 62901 ABSTRACT. —A compilation of records of fishes from Kentucky waters based on specimens deposited in museums, personal collecting, and accepted literature reports revealed that 229 species occur or did oc- cur in the state. A substantial amount of new distributional data is presented in the form of an annotated list including records of several species of fishes previously unreported from the state. Distributional statements in the checklist are based on individual spot maps completed for all Kentucky fishes. A list of five problematical species is included at the end of the checklist. INTRODUCTION The fish fauna of Kentucky is more diverse than that of any other in- land area of comparable size in North America except Tennessee and Alabama. Presently, 229 species are known to occur or to have occurred in Kentucky waters and only 10 or 11 are the result of introduction by man. A major factor contributing to the present completeness of our knowledge of the Kentucky fish fauna has been its rich history of ichthyological investigations going back to the time of one of North America's earliest ichthyologists, Constantine Samuel Rafinesque. Since Rafinesque's groundbreaking work on Ohio River valley fishes (1820) there have been four other reports on Kentucky fishes (Woolman 1892, Garman 1894, Evermann 1918, Clay 1975). Woolman's study is of im- mense historical value in documenting the distribution of many Ken- tucky fishes before most of the changes brought on by man took place.
