Maximum Size Of Fish Caught With Standard Gears And Recreational Angling, Kevin L. Pope, Gene R. Wilde, Daryl L. Bauer

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We correlated maximum lengths of freshwater fishes captured during 10 years with standard gears (i.e., gill nets, boat electrofishers and trap nets) and angling from Nebraska water bodies to determine which methodology provided better estimates of maximum size of fishes produced within a given water body. In general, maximum length of fishes captured with standard gears was smaller than maximum length of fishes captured with angling. Although significant (based on sequential Bonferroni adjustment) correlation was found in only one of nine sport fishes assessed, all correlations were positive indicating a general trend between maximum size of fishes captured with these …

Analysis Of Per Capita Expenditures Of Suburbanizing Communities In Maine, New England Environmental Finance Center

Economics and Finance

This study analyzes per capita expenditure trends among selected fast-growing Maine towns from 1970-2004. The ten communities studied are termed as “suburbanizing” towns. This term is used to describe towns that over the past 30-40 years have been in the process of transition from rural to suburban – in terms of their population and housing densities, their forms of government, and the services they provide, as well as other characteristics.1 Such towns are of particular interest because they have been absorbing a healthy percentage of the state’s population growth during this time period, often at the expense of Maine’s service …

Final Report: Evaluation Of The Morphoedaphic Index And Sediment Diatoms For Inference Of Pre-European Settlement Total Phosphorus Concentration In Epa Region 10 Lakes, Rich Miller, Aaron Hook, Richard Petersen, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Water quality in many Northwest lakes has declined over the past century due, in part, to increased anthropogenic nutrient loading (Edmonson and Lehman, 1981). Under the Clean Water Act, resource managers such as the Washington Department of Ecology, Oregon Department of Environmental Quality, and tribes are responsible for restoring and protecting the integrity of these waters. Targets for restoration or criteria for impairment are not well defined, however, and may naturally vary by geology, hydrology, morphometry, and climate.

One way to determine whether lakes are impaired and to identify restoration targets is to assess lake reference conditions (EPA 2000). Reference …

Assessing The Health Of Fringing Salt Marshes Along The Fore River And Its Tributaries, Pamela A. Morgan, Lucas Curci, Cayce Dalton, Jeremy Miller

Environmental Studies Faculty Publications

Casco Bay has experienced two significant oil spills in recent history - the Tamano Tanker spill in 1972 and the Julie N spill in 1996. In addition, the Fore River and its tributaries have experienced numerous small spills over the years, including the August 2002 fuel oil spill (2,900 gallons) and the April 2003 jet fuel spill (6,000 gallons). The impacts of these spills on the fringing salt marshes that line the edges of the Fore River and its tributaries are not well understood. Are these salt marshes resilient enough to withstand these impacts and still act as healthy marshes …

Mass Loading Measurements In Amargosa Valley, John C. Sagebiel, Alan W. Gertler, Amy J. Smiecinski, David Shafer

Publications (YM)

This work will be conducted under Task DRI-FI-001, “Mass Loading Measurements in Amargosa Valley.” The objective of this task is to measure, with known accuracy, the levels of atmospheric mass loading (mass concentration of suspended particulates) accompanying soil surface disturbing activities in Amargosa Valley. Mass loading is used in the biosphere model to calculate inhalation exposure for the human receptor, the maximally reasonably exposed individual (RMEI). The mass loading currently used in the biosphere model is based on literature data from the analog sites rather than on site-specific conditions. This work is subject to the Nevada System of Higher Education …

Side-By-Side Comparison Of Young Grab And Composite Petite Ponar Grab Samples For The Calculation Of The Benthic Index Of Biological Integrity(B-Ibi), Daniel M. Dauer, Michael F. Lane

Benthic Applications

(First paragraph) The Virginia Department of Environmental Quality (DEQ) intends to unite elements of its National Coastal Assessment Program (NCA) with its Chesapeake Bay Probabilistic Benthic Monitoring (CBP-PBM) Program beginning in the summer of 2005. The primary motivations for this decision were two-fold. First, the probable reduction of federal grant support for the NCA Program after the summer of 2004 would require considerable restructuring of the of DEQ’s estuarine probabilistic monitoring to continue with a comprehensive program in the future. Second, the current CBP-PBM Program has not provided sufficient data for the assessment of minor tidal tributary segments using the …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

On October 22, 2002, 5000 six-page surveys (Appendix 3) were sent to a stratified-random sample of Nebraska anglers drawn from the 2001 licensed anglers database. The database included all anglers who purchased a fishing license in 2001 as well as all lifetime fishing permit holders who purchased their license before or during 2001. The database did not include those possessing a free permit, such as veteran’s or senior citizen permits. The survey subsample (2.6% of the 2001-licensed angler database) was stratified such that the proportions of surveys in the subsample (4366 residents and 634 non-residents) matched the proportions of resident/non-resident …

The Effects Of Nutrient Concentrations On Macroinvertebrate Distributions In Georgia, Paula Michele Pollock Brossett

Theses and Dissertations

Nutrients are considered the second largest nonpoint source pollutant in Georgia's running water ecosystems. Nutrients can naturally occur in low amounts and are typically increased in streams as a result of industry, agriculture, silviculture, and urbanization. In large amounts, nutrients can cause many problems to occur in the stream ecosystem. Macroinvertebrates have been established as good indicators for determining the level of impairment of a stream; however, not much research has been done on how nutrients affect macroinvertebrates in a stream. Approximately 225 reference and impaired streams were sampled over a 3 - year field season, (index period from September …

Status and Trends for Virginia Chesapeake Bay

A marked decline in the water quality of the Chesapeake Bay has occurred over the past several decades. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality. The results of concentrated research efforts in the late 1970s and early 1980s stimulated the establishment of Federal and state directives to better manage the Chesapeake Bay watershed. By way of the …
