Fisheries Report No 66 - The Fishery For Perth Herring, Nematalosa Vlaminghi (Munro), C F. Chubb, N. G. Hall, R C.J. Lenanton, I. C. Potter
Fisheries Research Reports
Perth herring fishery over the last 30 years have been examined. While there are pockets of catches between Broome and Bunbury, those from the Swan Estuary and nearby inshore marine waters make by far the most important contribution to the fishery. In the Swan Estuary, the catches started rising in the 1950s in response to a demand by the rock lobster industry for bait and reached peak values in the late 1960s and early 1970s. Data are provided which demonstrate that catch per boat is a good index of catch per unit effort (CPUE) in the period since 1967 when …

Causes Of Uprooting And Breakage Of Specimen Giant Sequoia Trees, Douglas D. Piirto, W. Wayne Wilcox, John R. Parmeter, Jr., David L. Wood
Natural Resources Management and Environmental Sciences
A study of the causes of uprooting and stem failure in old-growth giant sequoia (Sequoia gigantea [Lindl.] Decne) indicated many factors, depending upon the type of failure (by root, stem, or earth). Advanced decay and fire scars were the most frequently associated with failure. In 21 of 33 study trees, one-third or more of the roots were judged too decayed to provide support. Twenty-seven study trees possessed basal fire scars, and 26 fell toward the scarred side. Nine Basidiomycetes, including Fomes annosus, Poria albipellucida, Poria incrassata, and Armillaria mellea, were associated with decayed wood. Carpenter ants were found …

Fisheries Report No. 65 - The Amateur Fishery For Marron (Cherax Tenuimanus) In Western Australia - Summary Of Logbook Data 1971-83, N. Morrissy, C. Fellows, N. Caputi
Fisheries Research Reports
The large, native crayfish called marron, Cherax tenuimanus, supports an extensive recreational fishery in the southwest of Western Australia. This report examines annual catch and effort statistics gathered from a Logbook programme, initiated in the 1971/72 season and supplemented by an end of season telephone survey from 1977. Logbook data gave estimates of relative abundance, but were too biased for projection to total catch and effort for the fishery, while telephone surveys gave unbiased estimates of total annual fishing effort (trips)l.
Relative abundance showed a significant decline in the major rivers and the most popular dam (Wellington) over the monitoring …

Fisheries Report No 60 - Amateur Net Fishing Survey Of Two Western Australian South Coast Estuaries In January 1981, D. I. Heald
Fisheries Research Reports
Following the return of the administration of fishing activities in Wellstead estuary and Beaufort Inlet to the Western Australian Government in October 1980, a survey of the amateur net fishing in these two estuaries was undertaken in January 1987, The purpose of the survey was to document usage, species catches and size composition of fish caught in respect of mesh size used and the success rate of amateur net fishermen as compared to their expectation. At the time of the survey, Wellstead estuary had been closed to the sea for 13 months and Beaufort Inlet for 27 months and the …

Wetlands Their Use And Regulation
United States Department of Commerce: Staff Publications
This report presents the findings and conclusions of OTA's analysis of approaches to wetlands use. Historically, wetlands were considered wastelands and conversion to other uses was actively encouraged. Two trends in recent decades, however, have altered this perception. First, there has been a growing appreciation for the esthetic and recreational qualities of wetlands; and second, there is now a general recognition of the hydrological and ecological services that wetlands provide. In spite of this increased awareness of the esthetic, recreational, and ecological values of wetlands, pressure to convert wetlands to cropland, commercial development sites, and other uses is still significant …

United States Geological Survey: Staff Publications
The High Plains aquifer, which underlies about 174,000 square miles in parts of eight states, is the principal source of water in one of the Nation's major agricultural areas. About 170,000 wells pump water from the aquifer to irrigate about 13 million acres in the High Plains. In 1978, the United States Geological Survey began a regional study of the High Plains aquifer to provide geohydrologic data and computer models of the aquifer needed to evaluate the effects of ground-water development. This report describes the geohydrology of the High Plains aquifer. The High Plains aquifer consists mainly of hydraulically connected …

An Assessment Of Lake Chubsuckers (Erimyzon Sucetta (Girard)) As Forage For Largemouth Bass (Micropterus Salmoides (Lacepede)) In A Small Nebraska Pond, Randle A. Winter
Nebraska Game and Parks Commission: Publications
Lake chubsuckers (Erimyzon sucetta (Girard)) were introduced into two ponds to examine their suitability as a sustainable forage for largemouth bass (Micropterns salmoides (Lacepede)). A summary of lake chubsucker suitability followed the criteria of Bennett and Childers (1966).
Lake chubsuckers were capable of growing larger than the size range for predation by most largemouth bass, however, their growth rate made them vulnerable to largemouth bass for several years. Young of the lake chubsuckers were not available as forage for age 0 largemouth bass. Even though lake chubsuckers possess round bodies and soft rayed fins, this was not demonstrated …

The Historical Development Of The Yakima-Tieton Irrigation District And Its Present Effect On Life In The Area Encompassing The District, Werner E. Lemke
All Graduate Projects
Irrigation played a very important role in the development of the Yakima Valley as we know it today. The Yakima-Tieton Irrigation District was chosen to show how an irrigation system functions and the part it plays on the lives of the plants, animals and people in its area. A brief historical study of the Tieton Division of the Yakima Project was made. The construction of the Tieton Unit was studied. A slide lecture with an accompanying tape was developed to acquaint junior high school students with the purpose, function and affects of the Yakima-Tieton Irrigation District.
Research Objectives In Vertebrate Pest Control, A J. Oliver
Research Objectives In Vertebrate Pest Control, A J. Oliver
Journal of the Department of Agriculture, Western Australia, Series 4
The European rabbit, introduced into Australia in 856 by an early settler for hunting, caused massive losses to agricultural production in Western Australia in 1940s and 1950s.
In those years most of the country's recources and efforts allocated to vertebrate pest problems were aimed at controlling this animal.
Research and control measures by Commonwealth and State agencies, including the introduction of myxomatosis, were largely responsible for reducing the rabbit problem to the comparatively minor one it is now.
Today, the Agricultural Protection Board is involved in the control of a much wider range of mammals and birds which cause losses …

A Groundwater Model Of Cache Valley, Utah, Calvin G. Clyde, Roland W. Jeppson, Win-Kai Liu
Reports
This report describes the development, calibration and use of quantitative, predictive management model for the groundwater in the Utah portion of the Cache Valley in northern Utah. The quasi-three-dimensional finite difference computer model was adapted from the U.S. Geological Survey’s Trescott and Larson model and simulates the groundwater levels and flows in the groundwater basin. The variable spacing grid system is 23 nodes x 38 x 2 and represents the complex natural system by a simpler approximation with one unconfined and one confined aquifer and the appropriate boundary and initial conditions. River nodes, spring nodes, and constant head nodes were …

Salt Lake County, Utah, watershed streams, drinking water treatment plants, and distribution systems were monitored for a period of one year or greater to determine the seasonal watershed precursor load, trihalomethane (THM) formation, and correlation between the two in the drinking water supplies. In addition, unit treatment processes were examined at Parleys, Big and Little Cottonwood water treatment plants, in the spring and late summer, to evaluate THM precursor reduction and THM formation. Additional studies were also conducted to appraise the potential contribution of natural sources to watershed THM precursor loading. Total organic carbon was used to estimate THM precursor …

The Impact Of Nitrification On Soil Acidification And Cation Leaching In A Red Alder Ecosystem, H. Van Miegroet, D. W. Cole
Watershed Sciences Faculty Publications
The objectives of this study were to investigate the impacts of internal nitrification on soil and soil solution acidity and on the rate of nutrient export through NO3– mediated leaching. This was achieved by comparing soil chemical properties and soil solution composition within a naturally N-rich red alder (Alnus rubra Bong.) ecosystem to those of an adjacent Douglas-fir [Pseudotsuga menziesil (Mirbel) Franco] forest where soil N levels were significantly lower and no measurable HNO3 production could be observed. In the red alder system, where > 100 kg ha–1 yr–1 of N were added through symbiotic N2 fixation, the net annual NO3– …

Soil Types And Drainage, Eric Bettenay, N. J. Schofield
Journal of the Department of Agriculture, Western Australia, Series 4
At least 90 per cent of the phosphorus entering the Peel-Harvey estuarine system comes from land cleared for agriculture, most of it from the coastal plain. These soils are naturally deficient on phosphorus and sulfur and this is supplied in superphosphate, which contains about 10 per cent phosphorus and 1 percent sulphur.
However, rain leaches some of this applied phosphorus from the land into drains and rivers which flow into the estuary. In 1981, farmers in the Harvey River-Mayfields Drain catchment lost the equivalent of 1,300 tonnes of superphosphate into the estuary. Between them they have in effect spent $120,000 …

The Extension Programme, W K. Russell, G. K. Palmer
Journal of the Department of Agriculture, Western Australia, Series 4
From the start of the Peel-harvey study in 1976, scientific research and extension have been closely linked. Trials, some involving major drainage works, have been set up on about 30 farms and several field days and seminars have been held.
The Peel-Harvey Study Group anticipates that farmer acceptance of the Department of agriculture's recommendations will reduce the phosphorus input to the estuary by 30 to 40 per cent over the next three to five years. At the same time farmers will benefit from modified cultural practices better suited to the sandy soils of the coastal plain.
Factors Affecting Water Quality And Microinvertebrate Distribution Within A Small Black Hills Stream, Henry G. Drewes
Factors Affecting Water Quality And Microinvertebrate Distribution Within A Small Black Hills Stream, Henry G. Drewes
Electronic Theses and Dissertations
A comparative evaluation of the benthic macroinvertebrate fauna was conducted concurrently with a physiochemical investigation on Slate Creek, Pennington County, South Dakota in the Black Hills. Water quality differences between years and among stations were detected in Slate Creek from both physiochemical and macroinvertebrate evaluations. The primary sources of disturbance to the Slate Creek study site during the sampling period were landscaping activities within the Deerfield Park Resort development and livestock activity. Increased runoff and elevated stream flows in 1982 were responsible for the variation in water quality between years. Water quality differences among stations indicated significantly (P < 0.05) higher turbidity and temperature immediately below the development site in 1981 and 1982. Significantly (P < 0.05) higher fecal coliform bacteria counts were observed at station 5 for both years, resulting from increased livestock activity. Phosphates and nitrates were highest at stations 4 and 5 but were not significantly (P > 0.05) different …

Electronic Theses and Dissertations
Brood-rearing period cover use by wild turkey (Meleagris gallopavo) hens with broods and those without, in Gregory County, South Dakota, was determined in order to formulate management suggestions for grassland/riparian woodland habitat. Two hens with broods and 12 hens without broods were studies through telemetry and direct observations form 5 July through 2 August and 3 August through 17 August of 1982 and 1982. Vegetational data were collected in 1983. Hens with broods selected for the grass/forb-dominated understory and 52% open canopy of south-facing savannah woodlands while their broods were less than 4 weeks of age. After 4 weeks, broods …
