Fisheries Report No 22 - The Western Rock Lobster Fishery 1971 - 1972, G. R. Morgan, E H. Barker
Fisheries Report No 22 - The Western Rock Lobster Fishery 1971 - 1972, G. R. Morgan, E H. Barker
Fisheries Research Reports
The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …
Fisheries Report No 25 - The Western Australian Amateur Fishery For Australian Herring (Arripis Georgianus) - Results Of The 1973 Creel Census, R C.J. Lenanton, N. G. Hall
Fisheries Report No 25 - The Western Australian Amateur Fishery For Australian Herring (Arripis Georgianus) - Results Of The 1973 Creel Census, R C.J. Lenanton, N. G. Hall
Fisheries Research Reports
Historically, the Western Australian production of Australian herring (Arrtpts georgtanus) has fluctuated from year to year in response to changing market demand. Prior to 1968, the annual catch taken by professional fishermen was relatively stable, ranging from 200 000 kg (approx. 500 000 pounds) to 450 000 kg (approx. 1 000 000 pounds). From 1968, commercial production has risen to a peak of 1 187 440 kg (2 617 857 pounds) recorded in 1972/73 (Table I). An increase in demand for herring as bait for the rock lobster fishery is considered to be the major factor involved in this observed …

Sealing Farm Dams, I A F Laing, R. G. Pepper
Sealing Farm Dams, I A F Laing, R. G. Pepper
Journal of the Department of Agriculture, Western Australia, Series 4
Research over the past 10 years has shown that it is technically possible to seal many leaking farm dams. In some situations a cheap chemical treatment is effective but in most cases it is cheaper to construct a replacement dam.
This article reviews the situation in western Australia and outlines some of the methods used for sealing dams.
Efficiency Of Sprinkler Irrigation Systems, T C. Calder
Efficiency Of Sprinkler Irrigation Systems, T C. Calder
Journal of the Department of Agriculture, Western Australia, Series 4
Shallow-rooted vegetable crops growing on sandy soils in hot, often windy summer weather, pose a difficult watering problem for most Western Australian vegetable growers.
Irregularities in wetting patterns are common. Wind effects are seldom taken into account in system design. The increasing popularity of knocker-type sprinklers makes these considerations particularily important.

Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma
Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma
Electronic Theses and Dissertations
A study of giant Canada geese (Branta canadensis maxima) nesting on stockponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, contributed the most to the use of the site. Distance from wetland to horizon and disturbance factors were two important variables measured to determine use of artificial nesting structures. First nests were initiated on 1 April 1974 and 8 April 1975. Twenty-five nests (16 percent) were located on artificial nesting structures, and …
Supply And Demand In Water Planning: Streamflow Estimation And Conservational Water Pricing, D. I. Carey, C. T. Haan
Supply And Demand In Water Planning: Streamflow Estimation And Conservational Water Pricing, D. I. Carey, C. T. Haan
KWRRI Research Reports
Recent studies indicated the need for development of surface water supplies in Kentucky. Rising resource costs make economically efficient reservoir designs increasingly important. This study was undertaken to provide methods in water supply reservoir design that increase system benefits.
Two major factors influencing reservoir design were studied: estimated future streamflow into the reservoir and demands placed on the reservoir. Standard reservoir sizing methods rely on historical streamflow data. This data is frequently limited and uncertainty in required storage estimates may result. To assess the reliability of a design, the use of mathematical models in simulation studies was proposed. Existing stochastic …
Key To Microscopic Fragments Of Plant Tissue In Prairie Dog Stomachs And Food Habits Of Prairie Dogs In South Dakota, Carol A. Summers
Key To Microscopic Fragments Of Plant Tissue In Prairie Dog Stomachs And Food Habits Of Prairie Dogs In South Dakota, Carol A. Summers
Electronic Theses and Dissertations
The purpose of this study was to (1) develop a reference collection and construct a key of plants occurring on prairie dog towns in southwest South Dakota; (2) determine plant species eaten by prairie dogs by analyzing stomach and pellet samples; and (3) relate the availability of plant species and preference in the feeding habits of prairie dogs. Two prairie dog towns of different vegetation were studied. Four burrows in each of two vegetative types for each town were randomly selected. Prairie dogs and pellet samples were collected from these burrows; plant cover was measured in four concentric circles for …
Population Status Of Beaver On The Free-Running Missouri River In Southeastern South Dakota, Robert J. Vanden Berge
Population Status Of Beaver On The Free-Running Missouri River In Southeastern South Dakota, Robert J. Vanden Berge
Electronic Theses and Dissertations
One hundred sixty two beaver (Castor canadensis) harvested by trappers from the free-running Missouri River in southeastern South Dakota were examined from fall 1974 to spring 1976. Ninety two were males and 70 were females (131:100 sex ratio). Age specific sex ratios were not significantly different (P >0.05) from a 1:1 ratio for all age classes. The age structure of the sample was 69:26:45:15:4:3 for age classes zero through five, respectively. Minimum breeding age for female beaver was 2.5 years. Seventy-eight percent of all females (>2.5 years old) collected after the breeding season contained corpora lutea and viable fetuses. …
