Trammel Netting and Seinincx <br />Trammel net sets were made in deep pool habitat in stratum B <br />between RM 6.3 and 8.4 September 14-16. Results are shown in Table <br />9. Only five species of fish were captured: carp, flannelmouth <br />sucker, channel catfish, northern pike, and smallmouth bass. The <br />three northern pike were the only representatives of this species <br />above stratum A and were smaller (380,381,403 mm) than those <br />observed in the lower Duchesne or adjacent Green River. <br />Limited seining of backwater, riffle, side-channel, and low <br />velocity flow-through habitats in stratum B resulted in <br />identification of 8 species of fish (Table 10). Four of these <br />species were documented only in fall seining and not with other <br />sampling methods. These were red shiner (Notropis lutrensis) sand <br />shiner (Notropis stramineus) fathead minnow (Pimephales promelas) <br />and black crappie. <br />All methods used to sample for fishes in the Duchesne River in 1993 <br />resulted in capture of 22 species (7 native, 15 non-native). <br />Thirteen species were sampled only by electrofishing and four <br />species only by seining. Five species were sampled by multiple <br />sampling methods (Table 11). <br />28 <br />
