Fisheries Research Report No. 124 - The Evaluation Of A Recreational Fishing Stock Enhancement Trial Of Black Bream (Acanthopagrus Butcheri) In The Swan River, Western Australia, C J. Dibden, G. Jenkins, Gavin A. Sarre, R C J Lenanton, Suzanne G. Ayvazian

Fisheries Research Reports

During 1995, a study was undertaken to monitor and evaluate the recovery of Swan River black bream stock which had been supplemented with fish produced from a captive-breeding program. Fish were individually tagged and subsequently released into the Swan River. The objectives of the study were (a) to determine both the survival and the growth rate to a size at which hatchery-reared fish could enter the recreational fishery and (b) whether they could then be caught by the recreational fishers. Of the 767 fish released into the upper Swan River on 28 March 1995, 97 fish (12.6%) were recaptured to …

It was found that in some areas there is real capacity for changing land use to impact on recharge to the watertable.


Estauarine And Coastal Marine Waters: Bioassessment And Biocriteria Technical Guidance, George R. Gibson, Michael L. Bowman, Jeroen Gerritsen, Blaine D. Snyder Dec 2000

Estauarine And Coastal Marine Waters: Bioassessment And Biocriteria Technical Guidance, George R. Gibson, Michael L. Bowman, Jeroen Gerritsen, Blaine D. Snyder

Miscellaneous Articles, Papers, and Reports

(First paragraph) This technical guidance document is based on the concept that bioassessment and biocriteria programs for estuaries and near coastal waters are interrelated and critical components of comprehensive water resource protection and management. Understanding how estuarine ecosystems function and respond to human activity requires a holistic approach to protection and management that integrates biological assessments into the more traditional chemical and physical evaluations. Section 101 of the Clean Water Act requires federal and state agencies to “restore and maintain the chemical, physical, and biological integrity of the nation’s waters.”

The Effectiveness Of The Asos, Mmts, Gill, And Crs Air Temperature Radiation Shields*, K. G. Hubbard, X. Lin, E.A. Walter-Shea

School of Natural Resources: Faculty Publications

Periodic upgrades of air temperature measurement systems in surface weather station networks cause data discontinuities. From a climatological viewpoint, it is necessary to evaluate the air temperature data discontinuities when air temperature radiation shields are upgraded. This study was undertaken to investigate the effectiveness of four common air temperature radiation shields including the Automated Surface Observing System (ASOS), the Maximum–Minimum Temperature System (MMTS), the Gill, and the Cotton Region Shelter (CRS) shields. The solar radiation shielding effectiveness for each shield under typical grass ground surface and different artificial surfaces (black, white, and aluminum) were investigated. The shield effectiveness was evaluated …

Environmental Finance Charette, Hyannis Park On Lewis Bay: A Case Study, New England Environmental Finance Center, Environmental Finance Center Of University Of Maryland

Water

The town of Yarmouth currently has a $30 million septic sludge treatment plant and transport lines in place. The vast majority of the dwellings and businesses in the Hyannis Park area are on septic systems that are viable and Title 5 compliant, regardless of age. Conventional, "non-failing" septic systems, however, were never intended to remove form their effluent nutrients such as nitrogen. These have become recognized as an environmental threat only as our understanding of the impacts of excess nutrients on ecosystems has increased in recent decades.


Managing Sprawl In The Land Of Unintended Consequences, Robert S. Bucci Sep 2000

Managing Sprawl In The Land Of Unintended Consequences, Robert S. Bucci

New England Journal of Public Policy

Americans witnessing the bulldozing of their country’s pastures, farmlands, and sensitive habitats to erect suburban housing tracts and commercial centers have come to realize that the remaining open land may be too precious to waste. Residential and commercial development is no longer quickly embraced to stimulate economic progress and prosperity. Municipalities are learning that development often extracts a price — sometimes the loss of community character and local charm, sometimes tax revenues that fall short of increased expenditures, and sometimes just plain ugliness. Responding to the new reality, many community officials have initiated unilateral ordinances regulating the development of open …

Relationships Between Abundance Of Physically Complex Habitat And Benthic Macroinvertebrate Community Parameters In The James River, Nelson County, Va, Tammy Lee Shumaker Aug 2000

Relationships Between Abundance Of Physically Complex Habitat And Benthic Macroinvertebrate Community Parameters In The James River, Nelson County, Va, Tammy Lee Shumaker

Theses & Honors Papers

This study shows the importance of structurally complex habitat on abundance and diversity of organisms in a benthic macroinvertebrate community in the James River, Nelson County, Virginia. Structural complexity was manipulated by attaching stones to five concrete blocks (12.8 ± 0.97% coverage; mean ± SE) and comparing organism abundance on these blocks and blocks lacking stones (0% coverage). Concrete blocks were randomly placed at a site in the James River on November 14, 1999 and collected on December 12, 1999. Macroinvertebrates and particulate organic and inorganic matter on the blocks were collected. Total invertebrate abundance, abundance of eight individual taxa, …

An Analysis Of Deer–Vehicle Collisions: The Case Of Ohio, Kurt A. Schwabe, Peter W. Schuhmann, Michael J. Tonkovich, Ellen Wu Aug 2000

An Analysis Of Deer–Vehicle Collisions: The Case Of Ohio, Kurt A. Schwabe, Peter W. Schuhmann, Michael J. Tonkovich, Ellen Wu

Human Conflicts with Wildlife: 2002 Symposium

The costs of deer-vehicle collisions (DVCs) in Ohio are estimated to be in excess of US$ 52 million annually. The intention of this paper is to identify factors contributing to the abundance of DVCs in Ohio, calculate the average cost of a deer–vehicle collision event, and illustrate the potential gains in economic efficiency from alternative approaches for reducing DVCs. Our results suggest that large potential economic gains from reducing DVCs in Ohio exist and that the optimal strategies for achieving these reductions seem to combine both changes in deer management schemes and deer-vehicle mitigation strategies.


Economic Analysis Of A Large Scale Oral Vaccination Program To Control Raccoon Rabies, Philip Kemere, Michael K. Liddel, Phylo Evangelou, Dennis Slate, Steven Osmek Aug 2000

Economic Analysis Of A Large Scale Oral Vaccination Program To Control Raccoon Rabies, Philip Kemere, Michael K. Liddel, Phylo Evangelou, Dennis Slate, Steven Osmek

Human Conflicts with Wildlife: 2002 Symposium

Since the late 1980s, results of oral vaccination trials in several states have provided growing evidence that this vaccination method may be effective for controlling the spread of rabies in raccoons (Procyon lotor). This study examines the economic feasibility of using oral vaccination on a larger scale than previous trials. We analyze the benefits and costs associated with a hypothetical barrier that would stretch from Lake Erie to the Gulf of Mexico, combining natural geographic features provided by the Appalachian Mountains with oral vaccination zones. The goal of this barrier would be to prevent the raccoon rabies variant …


Cormorant Depredation Losses And Their Prevention At Catfish Farms: Economic Considerations, James F. Glahn, Scott J. Werner, Terry Hanson, Carole R. Engle Aug 2000

Cormorant Depredation Losses And Their Prevention At Catfish Farms: Economic Considerations, James F. Glahn, Scott J. Werner, Terry Hanson, Carole R. Engle

Human Conflicts with Wildlife: 2002 Symposium

Although several piscivorous birds are involved in depredation conflicts with southern aquaculture, the double-crested cormorant causes some of the most widespread and significant problems to catfish, the dominant industry. Unlike other agriculture commodities, catfish losses due to predation cannot be directly measured, so we review several approaches taken to estimate these losses. Although these approaches are valid for predicting the costs of simply replacing these fish at the time of predation, they have been criticized because they failed to consider the functional relationships between predation and output parameters at harvest. Recent controlled experiments are reviewed that confirm previous estimates of …


Fundamentals Of Economic Principles And Wildlife Management, Peter W. Schuhmann, Kurt A. Schwabe Aug 2000

Fundamentals Of Economic Principles And Wildlife Management, Peter W. Schuhmann, Kurt A. Schwabe

Human Conflicts with Wildlife: 2002 Symposium

This paper presents an overview of the economic fundamentals involved in wildlife management, with special consideration for cases involving harmful wildlife-human interactions. The process of benefit-cost analysis is used as a unifying platform for incorporating both theoretical and empirical issues. Topics such as external market effects and public goods are detailed in order to give the reader a theoretical foundation for understanding the economic perspective on the problems associated with defining and attaining optimally managed wildlife populations. To these principles we add practical considerations for measuring the costs and benefits associated with wildlife populations. Different categories of wildlife values, such …


Damage Abatement And Compensation Programs As Incentives For Wildlife Management On Private Land, Jonathan K. Yoder Aug 2000

Damage Abatement And Compensation Programs As Incentives For Wildlife Management On Private Land, Jonathan K. Yoder

Human Conflicts with Wildlife: 2002 Symposium

Public damage abatement and compensation programs may be used to alter private incentives for damage abatement and habitat provision. A model is developed that explains the economic logic behind prevalent characteristics of public wildlife damage programs. The model is supported with an examination of a broad cross-section of wildlife agency policy and law. The model can be used by wildlife managers and policy makers as a conceptual framework for understanding the incentive effects of compensation and abatement policy.


The Endangered Species Act And Private Landowner Incentives, Jeffrey A. Michael Aug 2000

The Endangered Species Act And Private Landowner Incentives, Jeffrey A. Michael

Human Conflicts with Wildlife: 2002 Symposium

While intended to increase the habitat available to endangered species, the restrictions of the Endangered Species Act (ESA) increase the costs of harboring an endangered species to private landowners and create incentives for private landowners to reduce habitat. This paper illustrates the incentive for habitat destruction with a simple model of private land use under the ESA, and uses it to predict the effects of changes in policy or biological conditions on private landowner incentives. Many anecdotal accounts and recent empirical research support the predictions of the model. Because of the ESA’s perverse incentives, many have proposed replacing the punitive …


Economic Considerations Of Damage Assessment, Richard M. Engeman Aug 2000

Economic Considerations Of Damage Assessment, Richard M. Engeman

Human Conflicts with Wildlife: 2002 Symposium

Cost-effectiveness is the fundamental economic test of any damage control or damage mitigation strategy, and damage assessment is the essential component for determination of cost-effectiveness. However, there are many potential costs associated with making damage assessments. The sampling and measurement required to produce a damage assessment have associated effort and costs, but even greater costs can be incurred due to inappropriate management decisions resulting from inaccurate damage assessments. Other costs can result from using an assessment method that is unsuited to management objectives, or by misinterpreting or not understanding the relationship between observed damage and actual losses. The concepts of …


Spreadsheets, Response Surfaces, And Intervention Decisions In Wildlife Damage Management, Ray T. Sterner Aug 2000

Spreadsheets, Response Surfaces, And Intervention Decisions In Wildlife Damage Management, Ray T. Sterner

Human Conflicts with Wildlife: 2002 Symposium

An a priori approach to examining the economics of performing management activities to reduce agricultural and resource damage by wildlife is described. Computer spreadsheet procedures are used to derive response surfaces of potential net savings and benefit:cost indices for selected crop- or resource-protection activities. Tabular and graphical displays of these indices afford decision-making aids for wildlife-damage interventions. An example based on the use of an acute rodenticide, zinc phosphide (Zn3P2), for vole (Microtus spp.) control in alfalfa (Medicago sativa) is described. Iterative calculations were derived for 1,260 possible combinations of 3 field-size, 6 …
