Theses and Dissertations

Fish culture for both food and sport utilization has been greatly increasing throughout the world. The editor of Fish Farming Industries (1973) predicted an increase by 1977 in the United States of 83% for catfish producers, 49% for trout farmers, and 91% for bait dealers. Concomitant with the renewed interest in fish culture has been a corresponding need to further understand fish diseases.


Endemic Whitefishes Of Bear Lake, Utah-Idaho: A Problem In Systematics, Robert G. White May 1974

Endemic Whitefishes Of Bear Lake, Utah-Idaho: A Problem In Systematics, Robert G. White

All Graduate Theses and Dissertations

The systematic status of whitefishes endemic to Bear lake, Utah-Idaho, has remained tenuous since their original description. Clarification of this problem was the major objective of the present study. The general approach was an integrated one, including examination of morphological, biochemical and ecological parameters; artificial hybrids were produced and compared with questionable groups from the natural population.

Morphological analysis revealed five forms of Bear Lake whitefishes Prosopium gemmiferum (Bonneville cisco) and P. abyssicola (Bear lake whitefish) were well differentiated from other forms and were treated as originally described. The P. spilonotus (Bonneville whitefish) group, however, was found to be made ...

Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley May 1974

Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley

All Graduate Theses and Dissertations

Spraying with the chemical herbicide 2,4-D is the most widely used method of controlling big sagebrush. Spraying is very effective in increasing forage production and generally is not poisonous to either man or animals.

Two procedures can be used to calculate the internal rate of return to big sagebrush control: standard and modified discounting. Standard discounting assumes all nonuse costs are incurred in the year of treatment, and the annual income stream is constant throughout the effective life of treatment. Modified discounting correctly assumes the nonuse cost is incurred in the period of deferment, and the income stream does ...
