Fisheries Across the Eastern Continental Divide
Fisheries Across the Eastern Continental Divide Abstracts for oral presentations and posters, 2010 Spring Meeting of the Southern Division of the American Fisheries Society Asheville, NC 1 Contributed Paper Oral Presentation Potential for trophic competition between introduced spotted bass and native shoal bass in the Flint River Sammons, S.M.*, Auburn University. Largemouth bass, shoal bass, and spotted bass were collected from six sites over four seasons on the Flint River, Georgia to assess food habits. Diets of all three species was very broad; 10 categories of invertebrates and 15 species of fish were identified from diets. Since few large spotted bass were collected, all comparisons among species were conducted only for juvenile fish (< 200 mm) and subadult fish (200-300 mm). Juvenile largemouth bass diets were dominated by fish in all seasons, mainly sunfish. Juvenile largemouth bass rarely ate insects except in spring, when all three species consumed large numbers of insects. In contrast, juvenile shoal bass diets were dominated by insects in all seasons but winter. Juvenile spotted bass diets were more varied- highly piscivorous in the fall and winter and highly insectivorous in spring and summer. Diets of subadult largemouth bass were similar to that of juvenile fish, and heavily dominated by fish, particularly sunfish. Similar to juveniles, diets of subadult shoal bass were much less piscivorous than largemouth bass. Crayfish were important components of subadult shoal bass diets in all seasons but summer. Insects were important components of shoal bass diets in fall and summer. Diets of subadult spotted bass were generally more piscivorous than shoal bass, but less than largemouth bass. -

An Abstract of Molecular, morphological, and biogeographic resolution of cryptic taxa in the Greenside Darter Etheostoma blennioides complex Amanda E. Haponski Submitted as partial fulfillment of the requirements for The Master of Science Degree in Biology (Ecology-track) The University of Toledo December 2007 DNA sequencing has led to the resolution of many cryptic taxa, which are especially prevalent in the North American darter fishes (Family Percidae). The Greenside Darter Etheostoma blennioides commonly occurs in the lower Great Lakes region, where two putative subspecies, the eastern “Allegheny” type E. b. blennioides and the western “Prairie” type E. b. pholidotum , overlap. The objective of this study was to test the systematic identity and genetic divergence distinguishing the two subspecies in areas of sympatry and allopatry in comparison to other subspecies and close relatives. DNA sequences from the mtDNA cytochrome b gene and control region and the nuclear S7 intron 1 comprising a total of 1,497 bp were compared from 294 individuals across 18 locations, including the Lake Erie basin and the Allegheny, Meramec, Obey, Ohio, Rockcastle, Susquehanna, and Wabash River systems. -
Endangered Species
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.

State of California The Natural Resources Agency DEPARTMENT OF FISH AND GAME Biogeographic Data Branch California Natural Diversity Database STATE & FEDERALLY LISTED ENDANGERED & THREATENED ANIMALS OF CALIFORNIA January 2010 This is a list of animals found within California or off the coast of the State that have been classified as Endangered or Threatened by the California Fish & Game Commission (state list) or by the U.S. Secretary of the Interior or the U.S. Secretary of Commerce (federal list). The official California listing of Endangered and Threatened animals is contained in the California Code of Regulations, Title 14, Section 670.5. The official federal listing of Endangered and Threatened animals is published in the Federal Register, 50 CFR 17.11. The California Endangered Species Act of 1970 created the categories of “Endangered” and “Rare”. The California Endangered Species Act of 1984 created the categories of “Endangered” and “Threatened”. On January 1, 1985, all animal species designated as “Rare” were reclassified as “Threatened”. Animals that are candidates for state listing and animals proposed for federal listing are also included on this list. A state candidate species is one that the Fish and Game commission had formally noticed as being under review by the Department for addition to the State list. A federal proposed species is one for which a proposed regulation has been published in the Federal Register.

Man and the Changing Fish Fauna of the American Southwest

ROBERT RUSH MILLER Museum of Zool9gy, The University of Michigan TEE past 100 years have witnessed drastia changes in the rivers of Western North America and in their fish faunas. Deterioration of stream flow has greatly shrunk the ranges of many species, and other species have been denied access to large segments of their original distribution by the construction of barrier dams. Profound modifica- tion of pristine environments has restricted habitable waters, and the introduction and establishment of a host of exotics have brought about replacement as well as reduction of native forms through com- petition, predation, and hybridization. Some species and subspecies ave become extinct, and many others are endangered (Matthiessen, 959). These changes have been particularly marked in areas of ricted water supply such as characterize the arid Southwest ,;(Fig: 1 . Much of this region is embraced by the Basin and Range ProvinCe *: (Fenneman; 1931, pl. I), including the Great Basin, Sonoran Desert; - and the Chihuahuan Desert of northern Mexico. Only about 100 species of strictly fresh-water fishes are known west of the Rocky Mountains and north of Mexico—a depauperate - fauna characterized by relicts, monotypic genera, and much regional The initial version of this paper was presented at the Fifth Annual Sym- posium on Systematics, Missouri Botanical Garden, St. Louis, on October 25, , 1958, under the general subject "Taxonomic Consequences of Man's Activities."
