Reports
To document continued compliance with Federal law, the Anadromous Fishes Program of the Virginia Institute of Marine Science (VIMS) has monitored the size and age composition, sex ratio and maturity schedules of the spawning striped bass stock in the Rappahannock River since December 1981 utilizing commercial pound nets and, since 1991, variable-mesh experimental gill nets. Spawning stock assessment was expanded to include the James River in 1994 utilizing 11 commercial fyke nets and variable-mesh experimental gill nets. The use of fyke nets was discontinued after 1997. In conjunction with the monitoring studies, tagging programs have been conducted in the James …
Horse Creek Fen, Birdwood Creek And Kelly Ranch Inventory, Robert F. Steinauer
Horse Creek Fen, Birdwood Creek And Kelly Ranch Inventory, Robert F. Steinauer
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Horse Creek Fen preserve is a complex of wetland communities (Sandhills fen, Sandhills freshwater marsh, and northern sedge wet meadow) associated with Horse Creek, a ditched stream that drains the Allen Valley fen. Fen vegetation on the preserve is limited to approximately 20 acres on the western boundary of the preserve where it abuts the eastern end of the Allen Valley fen (Steinauer et al. 1996). The fen vegetation is surrounded primarily by Sandhills freshwater marsh, which in turn is surrounded by northern sedge wet meadow. Additional Sandhills freshwater marsh occurs near the eastern boundary of the preserve. The eastern …
The Aquaculture Of Non-Endemic Species In Western Australia Silver Perch (Bidyanus Bidyanus), Tina Thorne, H. G. Brayford
The Aquaculture Of Non-Endemic Species In Western Australia Silver Perch (Bidyanus Bidyanus), Tina Thorne, H. G. Brayford
Fisheries management papers
The development of commercial aquaculture of a non-endemic species such as silver perch raises a number of important issues relating to translocation. These include the potential of the introduced species to: impact on genetic diversity; introduce disease; and impact on - the natural environment; and - the biodiversity of native species. This Management Paper has been drafted in liaison with the Department of Environmental Protection in accordance with the principles of rish assessment, taking into account the above issues. It is considered that the implementation of this policy will protect the natural environment and native fish species. It will also …

Floyd Bennett Field (FBF), 579 ha in extent, is a division of Gateway National Recreation Area. It is the site of a former airfield, constructed by filling salt marshes with dredged materials. Except for the portion known locally as the “North Forty,” all sections of FBF have been cut over to maintain low vegetation. A grassland management plan (GRAMP) for 165 ha was initiated in 1986, to maintain habitats for open-country birds. Over the next few years, encroaching woody vegetation was removed manually and mechanically from the management area. Since then, it has been maintained as a grassland and receives …

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.

Monitoring Relative Abundance Of American Shad In Virginia's Rivers Annual Report 1999, John E. Olney Sr., John M. Hoenig
Reports
A moratorium on the taking of American shad (Alosa sapidissima) in the Chesapeake Bay and its tributaries was established by the Virginia Marine Resources Commission (VMRC) beginning 1 January 1994. The prohibition applied to both recreational and commercial fishers. The moratorium was imposed at a time when commercial catch rates of American shad in Virginia's rivers were experiencing declines. Data from the commercial fishery were the best available for assessing the status of individual stocks. Catch-per-unit-effort (CPUE) data were compiled from logbooks that recorded landings by commercial fishermen using staked gill nets at various locations throughout the middle reaches of …

Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.
Aquaculture Plan For The Recherche Archipelago, Fisheries Western Australia.
Fisheries management papers
Land supply and land cost for aquaculture may become a limiting factor in the foreseeable future. At present, adequate appropriately zoned land is available at reasonable cost. The most prospective land for aquaculture in or near Esperance is where suitable zoned land occurs over saline ground water aquifers or adjacent to the coast. Careful site selection would be necessary to ensure water supply, waste water disposal, services and operational space can be achieved at reasonable cost.
A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group
A Quality Future For Recreational Fishing On The West Coast., West Coast Recreational Fishing Working Group
Fisheries management papers
The West Coast Region between Kalbarri and Augusta offers a wide range of recreational fishing opportunities.The West Coast Region also receives more fishing pressure than any other, with an estimated 380 000 anglers fishing each year. Already, the signs of a fishery under pressure are showing. Catch rates of dhufish around inshore reef systems such as the Three-mile are a far cry from the 1950s and 60s when people beachlaunched wooden dinghies to fish the inshore waters for these highly prized fish. Increasing pressure on stocks has led to growing community concerns that the future quality of recreational fishing is …
Extralimital Records Of The Mexican Free-Tailed Bat (Tadarida Brasilensis Mexicana) In The Central United States And Their Biological Significance, Hugh H. Genoways, Patricia W. Freeman, Cary Grell
Extralimital Records Of The Mexican Free-Tailed Bat (Tadarida Brasilensis Mexicana) In The Central United States And Their Biological Significance, Hugh H. Genoways, Patricia W. Freeman, Cary Grell
School of Natural Resources: Faculty Publications
Two new records of Tadarida brasiliensis mexicana are reported from Nebraska. The literature records of this taxon from the central United States are summarized. In this region of North America, these bats occupy a “natal range” where the species carries on regular reproductive activities and the populations are relatively stable, including California, Arizona, New Mexico, Texas, and Oklahoma. To the north of the natal range of T. b. mexicana is a “pioneering zone” where, under favorable conditions, the species is capable of reproducing and conducting its normal activities. The pioneering zone of the Mexican free-tailed bat includes Barber and Comanche …
Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman
Shifting Distributional Patterns Of Mammals In Nebraska, Russell A. Benedict, Hugh H. Genoways, Patricia W. Freeman
School of Natural Resources: Faculty Publications
New distributional records are presented for 20 species of mammals in Nebraska. The majority of these records appear to represent changes in geographic distribution rather than just better sampling in poorly known areas. One group of mammals, including the opossum, northern myotis, evening bat, red bat, woodchuck, white-footed mouse, and gray fox, is expanding westward, probably in response to increasing woodlands along river systems. Another group, including the meadow vole, masked shrew, and least weasel, is expanding southward, possibly in response to new prey species and changing microclimates. The eastern woodrat appears to be expanding northward in eastern Nebraska. The …

Protecting And Sharing Western Australia's Coastal Fish Resources. The Path To Integrated Management., Fisheries Western Australia
Fisheries management papers
The fisheries management framework of the 21st Century must not only be able to manage the level of exploitation by commercial and recreational fisheries, but also provide an agreed basis and process for changes in the way fish and aquatic resources are used and shared by this community. There is a clear need to counter inevitable pressure on stocks from the impact of a growing population, increasing coastal development and the demands of various key user groups. Unless we are proactive in dealing with the growing exploitation of fisheries along our State’s vast 12,000km coastline, it will be difficult to …

Status Of The Major Oyster Diseases In Virginia 1999 A Summary Of The Annual Monitoring Program, Lisa M. Ragone Calvo, Eugene M. Burreson
Reports
As a consequence of the relatively warm temperatures and high salinities severe epizootics of both H. nelsoni and P. marinus occurred in most tributaries in VA. In the upper James River, VA prevalences and intensities of P. marinus were the highest on record. The proportion of advanced infections (moderate and heavy intensity) in October was 60% at Wreck Shoal and 48% at Horsehead Rock suggesting that significant oyster mortalities occurred in these areas. 1 Record high levels of P. marinus were also observed in Virginia's other major tributaries. Of the 39 bay oyster populations surveyed in the fall, P. marinus …

Breeding Season Demography And Movements Of Eastern Towhees At The Savannah River Site, South Carolina, David G. Krementz, Larkin A. Powell
School of Natural Resources: Faculty Publications
The Eastern Towhee (Pipilo erythrophthalmus) has undergone population declines across much of its range, especially in New England. Despite being a widespread and, at one time, a common species, relatively little is known about its natural history, ecology, or demographics. We conducted baseline research on Eastern Towhees at the Savannah River Site, South Carolina, in 1995 and 1996 to estimate breeding season survival rates, nest success rates, breeding densities, and daily movements. We also were interested in whether towhees had differences in survival and movement rates between young and mature managed pine stands. We found that survival rates during the …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
For more than a decade, The Nature Conservancy (TNC) and state natural heritage programs, including the Nebraska Natural Heritage Program (NNHP), have used a “coarse filter/fine filter” approach to preserving biological diversity (The Nature Conservancy, 1994). This approach involves identification and protection of natural communities (coarse filter) as well as rare species (fine filter). Identifying and protecting representative examples of natural communities ensures conservation of most species, biotic interactions and ecological processes. Those species that “fall through” the community filters are generally the rare species. Identification and protection of viable occurrences of rare species serves as the fine filter for …

With the adoption of Conservation by Design in 1995, The Nature Conservancy recognized the importance of working at larger scales to achieve our mission which is: the long-term survival of all viable native species and community types through the design and conservation of portfolios of sites within ecoregions. The Conservancy set forth to design conservation plans on an ecoregional basis by working closely with various conservation partners. These plans are intended to provide a framework within which the Conservancy and our partners, such as the Natural Heritage Programs, can make decisions regarding conservation actions to be taken at the …
