GRABOWSKI*I Department of Biological Sciences, Clemson University, Clemson, South Carolina,29634-0326, USA J. JEFFERY ISELY U.S. Geological Survey, South Carolina Cooperative Fish and Wildlife Research Unit, Clemson University, Clemson, South Carolina, 29634-0372, USA Abstract.-The robust redhorse Moxostonta robustum is a large riverine catostomid whose distribution is restricted to three Atlantic Slope drainages. Once presumed extinct, this species was rediscovered in 1991. Despite being the focus of conservation and recovery efforts, the robust redhorse's movements and habitat use are virtually unknown. We surgically implanted pulse-coded radio transmitters into 17 wild adults (460-690 mm total length) below the downstream-most dam on the Savannah River and into 2 fish above this dam. Individuals were located every 2 weeks from June 2002 to September 2003 and monthly thereafter to May 2005. Additionally, we located 5-10 individuals every 2 h over a 48-h period during each season. Study fish moved at least 24.7 ± 8.4 river kilometers (rkm; mean ± SE) per season. This movement was generally downstream except during spring. Some individuals moved downstream by as much as 195 rkm from their release sites. Seasonal migrations were correlated to seasonal changes in water temperature. Robust redhorses initiated spring upstream migrations when water temperature reached approximately 12'C. Our diel tracking suggests that robust redhorses occupy small reaches of river (- 1.0 rkm) and are mainly active diumally.

    SPORT FISH OF OHIO identification DIVISION OF WILDLIFE 1 With more than 40,000 miles of streams, 2.4 million acres of Lake Erie and inland water, and 450 miles of the Ohio River, Ohio supports a diverse and abundant fish fauna represented by more than 160 species. Ohio’s fishes come in a wide range of sizes, shapes and colors...and live in a variety of aquatic habitats from our largest lakes and rivers to the smallest ponds and creeks. Approximately one-third of these species can be found in this guide. This fish identification guide provides color illustrations to help anglers identify their catch, and useful tips to help catch more fish. We hope it will also increase your awareness of the diversity of fishes in Ohio. This book also gives information about the life history of 27 of Ohio’s commonly caught species, as well as information on selected threatened and endangered species. Color illustrations and names are also offered for 20 additional species, many of which are rarely caught by anglers, but are quite common throughout Ohio. Fishing is a favorite pastime of many Ohioans and one of the most enduring family traditions. A first fish or day shared on the water are memories that last a lifetime. It is our sincere hope that the information in this guide will contribute significantly to your fishing experiences and understanding of Ohio’s fishes. Good Fishing! The ODNR Division of Wildlife manages the fisheries of more than 160,000 acres of inland water, 7,000 miles of streams, and 2.25 million acres of Lake Erie.

These species include eight freshwater drum, eleven walleye, two gizzard shad, eight flathead catfish and two round goby. Over the past three years 2,604 fish have been tagged downstream of the rock ramp. Twenty-nine of these fish were recaptured upstream during boat electrofishing assessments or by anglers. Based on the mean monthly discharge of the Cass River during April and May, the data suggests that white and redhorse suckers can move past the rock ramp during normal discharge years.

    DNR Confirms Virus in Lake St. Clair Fish FOR IMMEDIATE RELEASE July 11, 2006 Contacts: Gary Whelan 517-373-6948, Gary Towns 734-953-0241 or Mary Dettloff 517-335-3014 DNR Confirms Virus in Lake St. Clair Fish The Department of Natural Resources has confirmed that viral hemorrhagic septicemia (VHS), a virus that causes disease in fish but does not pose any threat to public health, is present in several fish species in Lake St. Clair. The virus has also been detected in fish in the past year in Lake Ontario by the Ontario Ministry of Natural Resources and New York Department of Environmental Conservation, in Lake Erie by the Ohio Department of Wildlife, and in the St. Lawrence River by the New York Department of Environmental Conservation. The virus was detected by the DNR/MSU Aquatic Animal Health Unit in muskellunge, yellow perch, gizzard shad, northern pike, silver redhorse, and shorthead redhorse collected this past spring in Lake St. Clair. DNR fisheries officials now believe VHS was a likely factor in the deaths of muskellunge, yellow perch, and gizzard shad observed during the spring of 2006 in the St. Clair River, Lake St. Clair, and the Detroit River< /span>. The timing of the die-offs corresponded with the end of the stressful winter season for all fish species and the beginning of spawning season for muskellunge. Spawning is extremely taxing and creates additional stress on fish, thus making them more vulnerable to infection and disease. VHS outbreaks tend to occur during the spring season since the virus thrives at water temperatures between 40 and 60 degrees.

    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.

    Quillback Carpiodes Cyprinus

    Supplemental Volume: Species of Conservation Concern SC SWAP 2015 Quillback Carpiodes cyprinus Contributors (2005): Scott D. Lamprecht and Jason Bettinger [SCDNR] Editors (2013): Scott D. Lamprecht and Mark C. Scott (SCDNR) DESCRIPTION Taxonomy and Basic Description The Quillback is a member of the family Catostomidae, which is represented by 8 genera and 25 species in the mid-Atlantic region (Rohde et al. 1994). This family is characterized by soft-rayed fins, a mouth located on the underside of the head, thick fleshy distensible lips, and paired fins attached low on the body (Rohde et al. 1994). Current taxonomic and genetic work indicates that Atlantic Slope Quillback-type fish that are found in South Carolina may represent an undescribed species. Quillback are high bodied, laterally compressed fish that range in length up to 500 mm (19.5 in.) (W. Starnes, pers. comm.). They have a long, falcate dorsal fin with 23 to 30 rays, a small conical head, a silver to golden body, large conspicuous scales about twice as high as wide, and a lateral line that runs the length of the body. Quillback lack mouth barbels as well as dorsal and anal fin spines. The Quillback’s first long dorsal ray does not usually reach the full length of the dorsal fin base, while the first dorsal ray of the similar Highfin Carpsucker typically is as long as the fin (Rohde et al. 1994; Jenkins and Burkhead 1994). Quillback feed on insect larvae and other benthic organisms. They are spring spawners that can attain an age of at least 11 years (Jenkins and Burkhead 1994).
