<br />mm, a predator-prey length ratio of 4.6:1. Our fish were of similar size <br />to those reported by McAda but had a predator-prey ratio of 5.8:1 using <br />overall mean lengths. On the average, our predators were considerably larger <br />relative to their prey and this may be why no catfish became lodged in the <br />esophagus of squawfish. <br />With only eight attempts at feeding on CCSP in this study and with <br />these attempts on fish that were small relative to the predator, data were <br />insufficient to make conclusions about the probability of channel catfish <br />becoming lodged in squawfish mouths in the wild. However, we feel this is <br />ample evidence to support the conclusion that squawfish do not prefer chan- <br />nel catfish as prey items and would feed on other species of fish whenever <br />possible. The absence of other squawfish with catfish lodged in their <br />esophagi in the numerous collections made by state and federal agencies <br />supports this conclusion (McAda, 1983). We agree with McAda that the mor- <br />tality of Colorado squawfish from channel catfish lodged in their throats <br />is probably uncommon and not an important factor in the decline in abundance <br />of this endangered species.
