Model To Predict Arkansas Gray Fox Fur Harvests, James H. Peck, Gary A. Heidt

Journal of the Arkansas Academy of Science

Linear regression analysis of total gray fox (Urocyon cinereoargenteus) fur harvests from 1954-1983 in Arkansas showed a high correlation with mean pelt values (r = 0.956). Single variable models using linear regression analyses of current season's pelt values (CSPV) and previous season's pelt values (PSPV) were designed to predict fur harvests. These models demonstrated high correlations for predicting harvests (r = 0.933 and r = 0.893 respectively). Regional analyses revealed a high correlation between mean pelt values and harvest for the Ozark Mountain region (r = 0.923), Ouachita Mountain region (r = 0.971 ), and Gulf Coastal Plain (r = …

Farm Debt In The Wheatbelt : 1984 Survey Results, R S. Kingwell

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

In recent years many farms in Western Australia's wheat-growing areas have experienced adverse seasons. For example, the 1983-84 season was characterised by a late start, dry spring and wet harvest which resulted in many farms suffering a combination of low yields and the downgrading or dockage of their grain.

Poor seasons and poor profitability prospects for wheat-growing caused some concern about farm indebtedness in these areas.

In late 1983, a Parlimentary select committee was appointed to inquire into rural hardship. The State Minister for Agriculture also announced that the Department of Agriculture would conduct a farm survey to determine the …

Interceptor Drains And Waterlogging Control, J W. Cox, T R. Negus

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

Department of Agriculture trials of seepage interceptor drains from 1972 to 1983 primarily assessed the effects of such drains on salt encroachment. Although these trials showed that the drains had little influence on salt storage within the topsoil, they did reduce waterlogging downslope.

To investigate this drainage effect further, the Department's Narrogin office surveyed 35 drains on 14 properties in the winter of 1981, followed by detailed crop measurements in December that year. Provided the drains were properly designed, surveyed and constructed, and well maintained, they could be expected to increase crop yields during a waterlogging year by about 1 …

The Green Movement: Implications For Animals, Ronnie Z. Hawkins

Environment Collection

The Green movement, a newly emerging political movement that is both global in scope and firmly anchored to each local region at the grassroots level, is destined to be of great import to those concerned with the status of nonhuman animals in our society. Closely allied with deep ecology and bioregionalism, Green thinking embodies an alteration in our perception of the human organism: no longer seen as separate from and superior to all the other components of the ecosystem, our species is placed in context as one among many interdependent forms of life, with the attainment of a sustainable balance …

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Iii. Harvest-Price Relationships, Joseph D. Clark, Gary A. Heidt, Tina Sheldon, James H. Peck

Journal of the Arkansas Academy of Science

Correlation and linear regression analyses between mean annual pelt price and total harvest of 13 Arkansas furbearer species between 1965 and 1983 were performed for state and regions (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta). Statewide, strong correlations (r > 0.80) were identified for bobcat (Felis rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), mink (Mustela vison), nutria (Myocastor coypus), opossum (Didelphis virginiana), and raccoon (Procyonlotor). Moderate correlations (r = 0.55 - 0.79) were identified for eastern spotted skunk (Spilogale putorius), muskrat (Ondatra zibethicus), river otter (Lutra canadensis), and striped skunk (Mephitis mephitis). Nonsignificant correlations (r < 0.468) were shown for beaver (Castor canadensis) and long-tailed weasel (Mustela frenata). Regional differences were noted for each species.

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 …

U.S./Japanese Fishery Relations: Reflections On The Past And The Unsettled Future, Matthew Axel

Marine Affairs Theses and Major Papers

U.S.-Japan fisheries history spans over a half-century of controversy. A variety of developments have taken place over this period from past to present illustrating this point. This paper will present this subject in three parts, corresponding to the historical developments that have taken place. The saga begins with U.S. post-World War II aid in rebuilding the Japanese tuna, whaling and salmon fleets. Round two examines the rapid expansion of the Japanese utilization of Alaska pollock and the development of the surimi trawlers in the early 1960s. Finally, round three, which will encompass the majority of the subject matter discussed, begins …

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 …

Premium Prices For Quality Fish: A Case Study Of The F/V Odin, John Sackton

Marine Affairs Theses and Major Papers

During 1982, the F/V ODIN, a fishing vessel from the Port of New Bedford, participated in a program to improve fish quality on board through use of innovative fish handling techniques. The captain and crew hoped to sell higher quality fish at a premium price. This thesis examines the prices the F/V ODIN received prior to participating in this experiment, the price differentials the vessel actually received for landing higher quality fish, and the impact of the program on the prices received by the ODIN following the project. Overall, the ODIN received a price premium equal to 7.2% of the …

The New England Fishing Industry: A Case For Altering Conditions Of Competition In Both The Fishery And In The Market, William Joseph Brennan

Marine Affairs Theses and Major Papers

The New England fishing industry is presented in detail including an historical review, a discussion of current difficulties, and an examination of the public policy dilemma between resource conservation and industry promotion. Continuing efforts to revitalize the United States fishing industry are discussed and underlying problems that have had a negative impact upon the New England industry are outlined. Finally, an alternative public policy approach is developed which addresses fundamental difficulties in the new England region. This approach calls for an elimination of federal financial assistance to the fishing industry and a reduction in the amount of fishery imports reaching …

Biology Of The Antarctic Krill (Euphausia Superba) And Fisheries Management Under The Convention On The Conservation Of Antarctic Marine Living Resources, Randa Ali Mansour

Marine Affairs Theses and Major Papers

Interest in the development of a commercial fishery for Antarctic krill, the lack of a legal regime to govern and promote rational exploitation of Antarctic living resources, and a desire to avoid future conflicts between claimants and non-claimants regarding the control of an Antarctic marine fishery, as well as the desire to set a precedent for management and exploitation of non-living resources were incentives for the negotiation of the Convention on the Conservation of Antarctic marine Living Resources (CCAMLR). Furthermore, the Antarctic Treaty Consultative parties wished to maintain and solidify their control and enhance their collective legitimacy in the Antarctic …

Interstate Fisheries Management Problems: The Case Of Striped Bass, Richard Randall Schneider

Marine Affairs Theses and Major Papers

The striped bass (Morone saxatilis), or rockfish, fishery has been important both commercially and recreationally for decades along the Atlantic seaboard. In recent years, though, the fishery has undergone a serious decline and, as a result, has elicited considerable public concern. Although specific reasons for the decline have not been pinpointed, it is clear that inconsistent management practices within the range of striped bass have done little to help the fishery's condition. An anadromous species, striped bass spawn in the fresh water reaches of estuaries, after which many of the individuals return to the coastal ocean. In the Atlantic, the …

Acidification Sources In Red Alder And Douglas-Fir Soils -- Importance Of Nitrification, H. Van Miegroet, D. W. Cole

Watershed Sciences Faculty Publications

Precipitation, throughfall, forest floor, and soil leachate samples were monitored continuously in 1981 and 1982 in a N-poor Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] forest and a red alder (Alnus rubra Bong.) forest growing adjacently on a glacial soil in western Washington. The purpose of the study was to quantify the relative importance of atmospheric vs. natural sources of H+ input to forest soil acidification, and to determine the role of N transformation processes in the overall H+ balance of soils with different N status. Rainwater samples had an avg pH of 4.7 and annual H+ deposition via precipitation averaged 320 …
