These were five iJhite Suckers (Catostomus commersoni), <br />three Fathead Minnows (Pimephales promelas), and one Speckled Dire. <br />On the basis of the two stations sampled, Foidel Creek proper <br />offers little aquatic habitat for fish. The fish captured at the <br />lower station were all young of the year and may have been displaced <br />individuals from a small man-made pond 200-300 meters upstream. <br />This pond, and others created by beaver dams, may offer limited <br />fish habitat along this creek. <br />Middle Creek. The numbers and kinds of fish captured are shown in <br />Table 70, Numbers and Kinds of Fish Captured at Each Statio- on <br />Middle Creek in August, 1975. The Brook Trout (Salvelinus <br />fontinalis) was an adult fish (309 millimeters iii total length) and <br />in good condition. However, as only one trout was captured ir, 50 <br />meters of stream, this introduced species was apparently not signi- <br />ficant. The predominate species of fish in Middle Creek in the <br />area of the two samplieg stations is the Mountain Sucker (Catost^mus <br />• platyrhynchus). Mountain Suckers are native and typically inhabit <br />smaller, cold headwater streams. This species seeds primarily on <br />algae, diatoms and other plant material which is scraped from the <br />surface of rocks and other objects (Everhart and Seaman (1971); <br />Baxter and Simon (1970)). <br />The White Sucker (Catostomus commersoni) was common at the lower <br />station on Middle Creek, although this species was not captured at <br />the upper station. White Suckers typically inhabit lakes and slow- <br />water areas in streams, especially where there is cover from bank <br />vegetation. This species feeds primarily on aquatic insects and <br />crustaceans, although young may consume a large amount of algae <br />(Carlander (1969); Everhart and Seaman (1971)). As can be seen in <br />Table 62, Numbers and Kinds of Benthic Macroinvertebrates Collected <br />in Surber Bottom Sample in July, August and September, 1975 at Each <br />Station on Middle Creek, aquatic insects were common at this station <br />. and probably ^_onstituted a primary fond source for White Suckers. <br />779-238 <br />
