<br />Reservoir, Grand County, Colorado. M.S.
<br />Thesis. Colo. State Univ., Ft. Collins.
<br />126pp.
<br />This study investigates the relationship of the
<br />sucker population to the trout population of
<br />Shadow Mountain Reservoir. Characteristics of
<br />the reservoir are described, and the behavioral
<br />characteristics-, age/growth, food and feeding
<br />habits, and migration and movement patterns of
<br />the suckers are studied. States recommenda-
<br />tions for the control of the sucker population
<br />as part of a trout management program.
