<br />sible that a substantial portion of the juvenile
<br />salmonids consumed by northern squawfish be-
<br />low McNary Dam were already dead. Thus, the
<br />number of live juvenile salmonids consumed by
<br />northern squawfish may be less than previously
<br />assumed, suggesting that estimates of the impact
<br />of northern squawfish predation on salmonid pop-
<br />ulations should be adjusted.
