Percent of three prey fishes available to (small enough to be <br />consumed) various percentages of all squawfish predators on three dates in <br />Fish Chalet Pond. Availability is based on measurement of prey body depth <br />and estimates of predator mouth widths. <br /> <br />All <br />N <br />squawfish <br />Percent <br /> <br />N <br />Carp <br />Percent <br /> <br />N Prey <br />Fatheads <br />Percent <br />Squawfish <br />N Percent <br /> 10 NOV 1986 <br />20 40.0 25 0.0 - - 20 0.0 <br /> 55.0 8.0 - 0.0 <br /> 5.0 28.0 - 10.0 <br /> 9 JUL 1987 <br />19 31.7 40 0.0 20 0.0 19 0.0 <br /> 31.6 7.5 0.0 0.0 <br /> 15.8 7.5 0.0 5.3 <br /> 5.3 7.5 15.0 10.6 <br /> 5.3 17.5 40.0 21.1 <br /> 5.3 22.5 70.0 52.7 <br /> 5.3 77.5 85.0 68.5 <br /> 12 AUG 1987 <br />20 90.0 20 0.0 16 75.0 20 0.0 <br /> 5.0 0.0 87.5 5.0 <br /> 5.0 5.0 93.8 15.0 <br />On 12 August 1987, another prey-to-predator size comparison was made <br />(Table 2). Only the largest 5% of squawfish had carp available to them, <br />and these were only the smallest 5% of the carp. Most fatheads (75%) were <br />available to most (90%) of the squawfish. Although a new cohort of small <br />fatheads had appeared since 9 July, fathead minnows were still not plenti- <br />ful and occurred in seine hauls in numbers nearly equal to squawfish. <br />L'S
