Accordingly, we oppose the <br />proposal to stock largemouth bass and black crappie in <br />McPhee. <br /> <br />Largemouth bass are repeat offenders when it <br />comes to predation on Colorado River. endangered fish. <br />Langhorst (1989), Hendrickson and Brooks (1987), and <br />Osmundson (1987) all report l~rgemouth bass predation <br />on both razorback sucker and Colorado squawfish. In <br />fact, Osmundson (1987) reported that largemouth bass <br />actually prefer young Colorado squawfish to other <br />species, including red shiner and fathead minnow, when <br />given a choice of prey. Osmundson (1989) also noted <br />black crappie predation on young Colorado squawfish in <br />floodplain grow-out. ponds along the.CQlorado River. <br /> <br />The Division's stocking proposal for McPhee <br />contends that largemouth bass and black crappie <br />escapement from NcPhee is unlikely. But the Division <br />cannot ensure that this is the case; it is the Bureau <br />of Reclamation, not the Division,:which operates the <br /> <br />tJ.do. <br /> <br />_.~.. <br /> <br />@ Primed on 100"/" recycled unbleached paper. <br /> <br />a member of Earth Share", <br />
