Many farms in Western Australia were cleared and developed before there was a full and clear understanding of the effects of bush clearing - that is salinization of soil and water supplies, wind and water erosion, waterlogging and soil structure decline. The productive capacity and inherent problems of the different soil types was also largely unknown.
Modern-day Conservation Farm Planning aims to provide a blue-print for the redevelopment of properties to ensure long term soil fertility, to prevent soil erosion and degradation by waterlogging and salinity. It also provides for a spread of reliable stock watering points and more efficient …

Fisheries Report No 71 - An Investigation Of The Mortality Of The Pearl Oyster, Pinctada Maxima, In Western Australia, Rand Dybdahl, David A. Pass
Fisheries Research Reports
A three year investigation into the cause of abnormally high mortality rates of the pearl oyster, Pinctada maxima, on the cultured pearl industry's lease sites in the North West of Western Australia was completed on 30 June 71983. The objective of this study was to determine environmental, physiological and pathological factors predisposing farm oysters to excessive Levels of mortality and, if possible, make recommendations to alleviate this problem.
As mass mortalities may have complex causes, complementary field and laboratory studies were instigated. The culture industry's method of collection, transportation and farm husbandry were examined. Environmental parameters were monitored. Various empirical …

The Trinidad And Tobago/Venezuela Fishing Agreement, Zaleena K. Chin-Yuen-Kee
Marine Affairs Theses and Major Papers
The twin-island Republic of Trinidad and Tobago is situated adjacent to the Republic Of Venezuela such that at one point Trinidad is merely seven miles off the northeast coast of Venezuela. Fishing activities of nationals of each country in the waters of the other are therefore common and often lead to conflict. In an attempt to solve the fishing problem a fishing agreement was negotiated. It came into force in 1978 and expired in 1984 whereupon negotiations commenced once more in an attempt to achieve new accord. The fishing industries of both countries and the conflicts which led to the …

Cooperatives: Their Effectiveness And Limitations For Small-Scale Fisheries Development, Hiroaki Yonesaka
Marine Affairs Theses and Major Papers
Increased experience in fisheries cooperatives of developing countries has called into question a long-held presumption about their desirability and feasibility. In this context, this study attempts to reformulate the cooperative approach for small-scale fisheries in a realistic policy framework. First, past failures of fisheries cooperatives are analyzed from three different angles: the uniqueness of the fishing industry, systems intrinsic to the cooperative, and development policy. Second, various possibilities of building viable cooperatives are explored by introducing two key concnpets: the strategic option and the operational option. On the one hand, the strategic option implies that it is imperative to integrate …

Community Ecology, Robert K. Rose, Elmer C. Birney

COMMUNITIES with Microtus tend to be structurally simple, usually grasslands or tundra, and to have no more than two species of Microtus and rarely more than six species of small mammals. Microtus often dominates both numerically and in total small mammal biomass, especially at higher latitudes. The small mammal community is most influenced by Microtus through its fluctuations in density, and thus also in biomass, by its relatively high level of diurnal activity, and by its year-round activity. Other species of small mammals may be adversely affected because Microtus usually is larger and behaviorally dominant and also because the mere …

Benthic Diatom Community Dynamics In The Colorado River: Interactive Effects Of Periodic Dessication And Current Regime, Christopher Gerard Peterson
Publications (WR)
The response to periodic desiccation of periphyton communities developed in eddy environments or in areas exposed to variable, direct current was examined. Algal communities were incubated on clay tiles for between 2 and 12 weeks in the Colorado River, directly below Hoover Dam from October, 1983 - January, 1984. Mean daily discharge from the dam decreased over this period. To assess the influence of these discharge changes on community dynamics, samples collected over the first 12 weeks of the investigation were compared to samples of the same age collected over the final 8 weeks.
The small diatom taxon Achnahthes spp …

A Proposal To Fertilize The Overton Arm And Gregg Basin Areas Of Lake Mead, Larry J. Paulson
Publications (WR)
Several limnological studies have been conducted in Lake Mead during the past decade. The recent studies clearly show that most of Lake Mead is deficient in nutrients, especially phosphorus, and very low in productivity. The reservoir-wide average total phosphorus concentration for 1981 - 1982 was only 9 mg/m3. This is below levels found In most oligotrophic lakes and reservoirs. Algal biomass, as measured by chlorophyll-a, averaged only 1.5 mg/m3. That also places Lake Mead in the oligotrophic range. Transparency, as measured by a Secchi disc, averaged 9-5 m in Lake Mead during 1981-1982. That far exceeds …

Toxicological Studies On Aquatic Contaminants Originating From Coal Production And Utilization: The Induction Of Tolerance To Silver In Laboratory Populations Of Fish And The Chronic Toxicity Of Nickel To Fish Early Life Stages, Wesley J. Birge, Jeffrey A. Black, James F. Hobson, Albert G. Westerman
KWRRI Research Reports
Aquatic toxicity studies were performed on two important coal-derived contaminants, silver and nickel. Silver was investigated with regard to metal-induced tolerance in laboratory populations of the fathead minnow (Pimephales promelas). Fish were exposed to acute silver concentrations following acclimation to sublethal exposures of this metal. Based on median lethal times (LT50), animals which had received 14 days prior exposure to 1.5 and 15 μg Ag/L were three to four times more resistant to silver than were previously unexposed organisms. This metal-induced resistance was not a sustained response. After organisms which had been acclimated to 15 μg/L had been transferred to …

Conference organizers and/or speakers included University of Colorado School of Law professors James N. Corbridge, Jr., David H. Getches, Lawrence J. MacDonnell and Richard B. Collins.
In general, water rights are a matter of state law. However, the availability and development of water are affected by important federal rights, policies and programs. In this conference, an outstanding group of private practitioners, government representatives and academics consider this important topic.
