Pheasant Use And Waterfowl Production On State And Private Lands, Charles R. Elliott

Electronic Theses and Dissertations

Ring-necked pheasant (Phasianus colchicus) use on state-owned game production areas was compared to that on privately-owned areas in east-central South Dakota. Four 80-acre and four 160-acre tracts of state lands were paired with private areas of the same size having the same amount of wetland and were selected from aerial photographs taken before the purchase of the state-owned areas. None of four nests were successful on private areas in 1968 and three of five nests were successful on game production areas. In 1969 three of 19 nests were successful on private areas and 10 of 21 nests were successful on …

Feeding Of Black Bullheads Ictalurus Melas (Rafinesque) In Experimental Cages, Kay R. Hill

Electronic Theses and Dissertations

Black bullheads, Ictalurus melas (Rafinesque), were grown experimentally from July 25, 1969, through October 21, 1969. The fish, collected from Lake Poinsett, were grown in five cages each with a water volume of 2.6 m³ and five cages each with a volume of 3.86 m³. The larger cages contained nearly 60 percent of the total 323 m³ of water volume in the cages. No significant difference in fish growth between the two cage sizes were observed. Fish in large cages gained 204.4 Kg and were fed 1550.8 Kg of food, for a food conversion of 6.60. Fish in smaller cages …

A Thermodynamic Analysis Of A Primary Waste Stabilization Pond, David W. Hendricks

Reports

Traditional design practice for waste stabilization ponds is based upon the premise that sufficient photosynthetic oxygen must be produced within the pond to satisfy oxygen requirements of the incoming waste flow. Thus, because algae production is proportional to pond surface area, surface organic loading rate is a principal design criterion (hydraulic detention time is the other) . That a possible adverse energy trade exists in the sequence of coupled reactions (aerobic waste degradation-photosynthesis) has been largely ignored. This work is focused on quantitatively articulating this energy trade, in terms of algae produced vis a vis waste degraded. This is done …

Some Ecological Relations Of Fairy Shrimps In Alkaline Habitats Of Nebraska, D. B. Mccarraher

Nebraska Game and Parks Commission: Staff Research Publications

Ecological studies on the distribution of fairy shrimps have been made from 246 sites in the sandhills region of Nebraska. New records for Nebraska have been established for Artemia salina, Branchinecta campestris, B. lindahli, B. mackini and Cyzicus mexicanus. Seasonal populations of shrimp have been located in habitats containing permanent fish populations. Water mineralization was the dominant environmental condition related to the distribution of phyllopods with sodium and potassium compounds predominating in the strongly alkaline lakes. Several of the Artemia lakes were classified as hydroxide sites. Many of the alkaline ponds, where B. lindahli and B. campestris flourish, are …

The Ocean Resource: A Scenario For Its Control, Ronald Poitras

Marine Affairs Theses and Major Papers

As man expands his horizons on planet earth, he is beginning to turn increasingly to the oceans as a source of resources, and at a pace commensurate with the growth of his needs and his technical ability. Traditionally the deep sea has always been a "no man's land," an unlimited source of space to be traversed and used infrequently. A scarcity of natural resources and an abundance of human extensions (i.e. technology) are together making deep ocean seclusion a thing of the past. Increasing use of a particular resource is a limited space sooner or later implies an increasing need …

Blind River Dolphin: First Side-Swimming Cetacean, Earl S. Herald, Robert L. Brownell Jr., Fredric L. Frye, Elkan J. Morris, William Evans, Alan Scott

United States Department of Commerce: Staff Publications

The blind river dolphin (Platanista gangetica), first written about by Pliny the Elder in A.D. 72, was found (10 November 1968) to be the first known side-swimming cetacean. The rudimentary eye lacks the lens, but anatomical evidence suggests that the eye may serve as a light sensor. The underwater sound emissions of this species, although similar to those of the Amazon River dolphin (Inia geoffrensis), appear to be produced constantly.

Fisheries Report No V (5) - Report On Marron In Farm Dams (Cherax Tenuimanus), N M. Morrissy

Fisheries Research Reports

A programme of selling marron (Cherax tenuimanus) to country dwellers for stocking farm dams, has been carried out by the Pemberton Trout Board for the past few years with considerable financial gain. In this case permission to sell the marron was granted by the Department of Fisheries and Fauna so as to encourage the provision of stocks of this large, freshwater crustacean for farmers in the dryer inland areas of the Southwest which are remote from sources of fresh fish and from natural stocks of marron.

The marron, however, have been sold indiscriminately, upon request, without any advice as to …

Virus Movement In Groundwater Systems, William A. Drewry

Arkansas Water Resources Center Technical Reports

The purpose of this study is to investigate the extent to which soil acts as an agent in the transmission of waterborne viruses. Since many waterborne outbreaks of viral diseases have involved small wellwater supplies contaminated by effluents from subsurface wastewater disposal systems, there is a great need for such information. Results of this study show that virus adsorption by soils is greatly affected by the pH, ionic strength, and soil-water ratio of the soil-water system and various soil properties. Also, it is shown that one cannot predict the relative virus adsorbing ability of a particular soil based on the …

Taxonomy Of The Common Dolphins Of The Eastern Pacific Ocean, Richard C. Banks, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

Delphinus bairdii Dall is a species of dolphin distinct from D. delphis Linnaeus, with which it has usually been synonymized. D. bairdii has a longer rostrum relative to the zygomatic width of the skull; the ratio of these measurements falls at 1.55 or above for bairdii and 1.53 and below for delphis. In the eastern Pacific Ocean, D. bairdii is found in the Gulf of California and along the west coast of Baja California, Mexico; D. delphis is presently found in the waters off California. Until approximately the beginning of the present century, bairdii occurred farther north in the …

Water Storage Has Not Kept Pace With Stock Numbers : South Stirling Survey Finding, A L. Prout

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

RESULTS of a survey on water storage capacity in the South Stirlings area indicate that farm water storage has not kept pace with increased clearing and stock numbers.

This has resulted in many farmers requesting advice on water conservation projects following two consecutive years of low rainfall runoff.

Shed Lambing In The Esperance Environment, T Marshall, F. F. Dixon

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

Neonatal lamb mortality is often high in Western Australia and losses as high as 33 per cent, have been recorded on private properties in the Esperance area. Surveys by Western Australian Department of Agriculture officers have indicated that more than threequarters of such lamb deaths occur after birth. About half these deaths result from the combined effects of weather and mismothering.

Work in Victoria has indicated that lamb mortality may be reduced by intensive lambing systems such as shedding and this trial was established to see if shedding could reduce lamb mortality in the Esperance environment.

Pasture Establishment In The Wheatbelt, M L. Poole

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

The value of legume based wheatbelt pastures is so great that considerable care is warranted during their establishment. Without such care patchy establishment or even complete failure is likely to occur.

IN THE WHEATBELT too many farmers still put less effort into their seeding of pasture species than their seeding of crops.

This may be because both compete for the farmer's time in the busy seeding period and it is the cereal crop which possesses the obvious cash value.

However, the total value of a good pasture has to be assessed over a period of several years because of its …

A Food Habits Study Of Whitetail Deer In The Black Hills, James Carl Schneeweis

Electronic Theses and Dissertations

Food habits of whitetail deer (Odocoileus virginianus) in the northern Black Hills were studied during fall and winter 1966067 and 1967-68 and also during summer 1967. Summer study was confined to aspen (Populus tremuloides) areas and involved stomach analysis and a pasture study. Fall and winter food habits were determined by stomach analysis only. Associated aspen vegetation was sampled to find a representative site for construction of a 0.7 acre enclosure. Two deer were placed in a utilization section of the enclosure for 18 days during mid-summer. Annual growth was clipped in a control section of the pasture to estimate …

Effects Of Aldrin On Young Pheasants Under Semi-Natural Conditions, Ronald Eugene Thill

Electronic Theses and Dissertations

Effects of aldrin on young pheasants were studied under semi-natural conditions in four one-acre enclosures during the summer of 1968. The center two-thirds of each plot was planted in corn; remaining peripheral cover was maintained in smooth brome and alfalfa. Prior to planting, center portions of two plots were sprayed with 2 pounds of aldrin per acre on Hay 20, while remaining plots served as controls. On June 12, four family units consisting of two broody pheasant hens and two bantam hens with 15 three-day-old chicks each were confined in plots. Hens and broods were given free run 10 days …
