Predation Of Upland Game And Its Management, Roger Wells

Great Plains Wildlife Damage Control Workshop Proceedings

There is probably no greater topic that elicits greater emotion in public wildlife discussions than that of predation. A variety of groups each with their own particular special interest surround the topic.

Some advocate complete protection of predators on the premise that their activities merely result in a "balance of nature." The opposite viewpoint argue just as strongly for the total elimination of Predators of valued wildlife in order to have greater number for man's enjoyment.

Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon

Publications (WR)

Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …

The European Wasp : A New Threat To W.A, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The European wasp was detected in Western australia for the first time in January and February 1977 in the metropolitan suburbs of Mosman Park, Cottesloe and Attadale.

So far it has only been found within an area of 8 km radius from Fremantle but the outer boundries of the infestation are still uncertain.

It is Department of agriculture policy to eradicate the European wasp, if possible, and to destroy all nests detected.

A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman

Publications (WR)

1. The waters of Las Vegas Bay, a heavily utilized recreational resource, receive discharges from a variety of municipal and industrial waste sources. The U.S. Environmental Protection Agency has determined, on the basis of numerous studies, that the present water quality violates state and federal standards and constitutes a public nuisance. Consultants have advised the Sewage and Wastewater Advisory Committee that rapid abatement of the alleged pollution conditions can be achieved by an advanced wastewater treatment (AWT) plant.

2. The major problems in Las Vegas Bay are an objectionable water color, excessive turbidity, noxious odors, and oxygen depletion in certain …

Distribution Of Stream Pollution In Lake Water, Richard W. Tew, Samuel S. Egdorf, James E. Deacon

Publications (WR)

Wastewater effluent-laden waters from Las Vegas Wash (LVW) form a density current that may be detected in Boulder Basin of Lake Mead at considerable distances from the wash estuary. This led to the suspicion that water from the inflowing stream [40 mgd (1.5 X 10⁵ cu m/day)] might not be rapidly diluted in the enormous volume of the lake [19 mil acre-ft (2.3 X 10¹⁰ cu m)], but might persist as a recognizable entity to the vicinity of the intake of a major water source for populous Clark County, Nev.

Because of the detection sensitivity implicit in the …

The Nature And Distribution Of Enteric Bacteria In Las Vegas Bay, Samuel S. Egdorf

Publications (WR)

The distribution of water and of enteric bacteria of possible fecal origin into Las Vegas Bay from Las Vegas Wash was determined. Determination of distribution patterns was attained by applying the concept of the population component ratio of enteric bacteria. The development and application of new techniques and methods implicit in the application of the "component ratio" concept are discussed. The unreliability of thoroughly referenced techniques and methods generally accepted as standard are treated in detail. Physical factors affecting the distribution and deposition of enteric bacteria (including those of special public health importance) in Las Vegas Bay are also discussed.

Oregon's Nutria Problem, Lee W. Kuhn, E. Paul Peloquin

Vertebrate Pest Conference Proceedings: 6th (1974)

The nutria or coypu, Myocastor coypus, is a large semi-aquatic rodent that superficially resembles an overgrown muskrat or a stunted beaver. They were introduced into Oregon from about 1930 to the 1950s. At one time Oregon had more than 600 fur farmers raising these animals for fur; now there are none. Some animals escaped and many others were released into the wild when it became apparent that pelt values were nonexistent and production costs greatly exceeded profits. Being prolific and quite mobile the nutria quickly spread through much of western Oregon. By the 1960s damage to agricultural crops was …

Some Concepts In Rangeland Management, R B. Hacker

Journal of the Department of Agriculture, Western Australia, Series 4

The arid and semi-arid zones of Australia occupy about 75 per cent of the land mass. The pastoral industries are located within these zones and, although productivity per unit area is low, the region nevertheless constitutes one of the nation's valuable renewable resources.

If properly managed, such a resource may be maintained as a productive asset indefinitely.

Sensitivity Of Vertebrate Embryos To Heavy Metals As A Criterion Of Water Quality, Wesley J. Birge, John J. Just

KWRRI Research Reports

Embryonic and/or larval stages of the leopard frog (Rana pipiens), domestic fowl (Gallus domesticus) and the goldfish (Carassiua auratus) were treated with cadmium chloride, mercuric chloride, lead chloride, zinc chloride and sodium arsenite. The principal objectives were (1) to determine the sensitivity of vertebrate embryos to certain metals which are of consequence in water pollution, and (2) to ascertain the suitalility of vertebrate embryos as bioassay organisms for monitoring metallic pollutants within water resources. Vertebrate embryos are found to be highly sensitive to the toxic effects of all the metals studied. Concentrations of mercury as low as 10 ppb, with …

Crayfish, Leech, And Snail Control

Great Plains Wildlife Damage Control Workshop Proceedings

We have effective results in controlling crayfish in our ponds using Baytex. Baytex is a higly toxic compound that effects the nervous system of many organisms. Used in small concentrations it will kill crayfish without hurting fish. We use Baytex at 40 ppb. We normally dilute the required amount of chemical with water and then mix it thoroughly in the pond. Leeches can be controlled using Dylox. Masoten is another trade name for dylox. The recommended rate of application is 1/2 ppm. This should be applied in a manner so it is thoroughly mixed in the ground. Recommened treatment for …

Grey Kangaroo Management Programme, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The Grey Kangaroo Management Programme, introduced in 1971 by the Department of Fisheries and Fauna, is designed to ensure the long-term conservation of the grey kangaroo, while at the same time recognising the right of the landholder to protect his primary production from damage.

One of the points which has arisen after examination of the programme is that some individual farmers are not fully aware of the requirements of the regulations.

Phytoplankton Successions And Lake Dynamics In Las Vegas Bay, Lake Mead, Nevada, Ervon R. Koening, Richard W. Tew, James E. Deacon

Publications (WR)

Phytoplankton successions, applications of the general growth equation, and physical measurements have been employed to investigate events occurring at the interface between industrial and sewage effluent contained in Las Vegas Wash and the waters of Lake Mead, Nevada. The data indicate that the entering waters tend to form a density current interrupted at intervals by dynamic effects generated in the lake. The dynamic relationships described here for the spring months suggest that a much more thorough understanding of physical, chemical and biological interactions is necessary to permit solution of the numerous problems of Las Vegas Bay discussed or alluded to …

A Mathmatical Model Of Primary Productivity And Limnological Patterns In Lake Mead, Lorne G. Everett

Publications (WR)

The temporal and spatial changes in chemical and biological properties of Lake Mead have been investigated, thereby indicating the sources of water pollution and the time of highest pollution potential. Planktonic organisms have been shown to indicate the presence of water problems. Macro- and micro-nutrient analyses have shown that primary productivity is not inhibited by limiting concentrations. A mathematical model has been developed, tested with one set of independent data, and shown worthy of management utility. Although the model works very well for the Lake Mead area, the physical reality of the Multiple Linear Regression equation should be tested on …
