To many people, Donegal Creek means trout fishing! The main stem 7 8 includes a 2.4 mile “delayed harvest fly-fishing” stretch, while the rest of the main stem and branches are open to “bait fishing.” Both the Pennsylvania Fish and Boat Commission and the Donegal Fish and Conservation Association stock trout during the spring and fall months. In addition to the stocked trout, an angler may encounter wild stream-bred brown trout when fishing the main stem and wild rainbow and brown trout (progeny from egg plant- ings) when fishing the west branch.

  • 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.

  • 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.

  • The Ohio Journal of Science — Index 1951-1970
    THE OHIO JOURNAL OF SCIENCE — INDEX 1951-1970 JANE L. FORSYTH AND CHRISTINE M. GORTA Department of Geology, Bowling Green State University, Bowling Green, Ohio 43403 INTRODUCTION It is almost 20 years since the first General Index to The Ohio Journal of Science, which covered the issues from the beginning (1900) through 1950, was published (Miller, E. M., 1953, published by The Ohio State University and The Ohio Academy of Science). It is time, therefore, for another general index, dealing with issues appearing since 1950. This is that index. Unlike the first index, there is no separate listing of full references by author; rather, this is simply a combining of all the entries from all the yearly indexes from 1951 through 1972. Basically these original entries remain unchanged here, though mistakes found in a few were corrected, and some have been slightly reworded in order to fit better into this multiple listing. Entries relating to book reviews occur only for the years of 1963 through 1970, because book reviews were not included in the earlier indexes. It should also be noted that, though a few of these books represent merely a reprinting of older, out-of-date books, these books are not so identified in the entries in this index. Preparation of this index has been mostly handled by Miss Christine M. Gorta, under the direction of Dr. Jane L. Forsyth, Editor of The Ohio Journal of Science from 1964 to 1973, but others have also contributed to this work—mainly Misses Lauran Boyles and Laura Witkowski—contributers whose efforts are gratefully acknowledged.

[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 these water quality standards, Chapter 3745-1 of the Administrative Code, 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. section 1251 et seq., 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 beneficial 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.

Some authorities regard this species to be inadequately diagnosed and its taxonomic status uncertain (Burr and Warren 1986, Robison and Buchanan 1988). This has led to uncertainty regarding its distributional status in several states and speculation about misidentifications. The species is generally treated as vulnerable to imperiled in most of the upper Mississippi River basin and Ohio River drainage. It is considered secure in only a few states in the middle and lower Mississippi River basin, although records in the Gulf Slope drainages in Texas and New Mexico are thought to potentially be based on misidentifications or introductions (Etnier and Starnes 1993, Natureserve 2008, Shute 1980).
