whether the proportions of small and large sguawfish found in <br />bass stomachs is equal to the proportion of each in the total <br />population. Also, a lab experiment will be set up to determine if <br />largemouth bass display a preference for a particular size of <br />first-year squawfish. An analysis of variance using a randomized <br />block design will be used to test for a preference. <br />H3: There is no difference in overall survival between small (X=59 mm TL) <br />and large (}=83 mm TL) stocked first-year squawfish. <br />Samples of squawfish collected at the end of the season will have <br />size-coded microtags examined to determine the percent of the total <br />remaining population that is made up of each original size-group. <br />These percents will be compared to the percents of each size-group <br />at the time of stocking. A binomial chi-square test will be used to <br />determine whether the proportions of small and large groups at Time <br />1 equals the proportions of each at Time 2. <br />H4: Largemouth bass do not display a preference for a particular prey <br />species when young squawfish and an alternative fish species are <br />both available. <br />A lab experiment will be set up whereby individual bass of three <br />general size-groups will be placed in tanks and offered equal num- <br />bers of squawfish and similar-sized-alternative prey species. The <br />tank environment will be such that differences in vulnerability <br />between prey species will be reduced so that preference can be <br />isolated as the cause of prey selection by bass. <br />H5: There is no difference in overall survival between squawfish <br />stocked in the spring and those stocked in the fall. <br />A known number of squawfish will be stocked into five ponds, and <br />later the size of the populations will be estimated to determine <br />percent survival. Percent survival of squawfish stocked in the <br />fall will be estimated the following spring. Those stocked in the <br />spring will have their survival estimated when they reach the mean <br />30
