<br />Summer Electrofishincr ~ ' <br />Fish population estimates were calculated for the two 1/4 mile <br />sections surveyed by electrofishing using techniques described by <br />Robson (1971) (Table 7). Only two species, carp and green sunfish, <br />were captured in stratum A (RM 2.25-2.50). Only carp were captured <br />in both passes. Calculations showed a projected population of carp <br />and green sunfish of 12.1 and 1.0 per 1/4 mile respectively. In <br />stratum B (RM 6.25-6.50) seven species were captured in the 1/4 <br />mile intensive sampling reach. Only two species, carp and <br />flannelmouth sucker, were captured in both passes. Calculated 1/4 <br />mile populations for these speces were: carp, 88.9; flannelmouth <br />sucker (Catostomus latipinnis), 11.6; channel catfish, 14.0; <br />smallmouth bass, 10.0; black bullhead (Ictaluras melas), 4.0; <br />green sunfish, 2.0; white sucker (Catostomus commersoni), 1.0. <br />Difficulty in electrofishing in deep pool habitat was encountered <br />in both 1/4 mile reaches. <br />Limited additional late-summer electrofishing was conducted in <br />strata A and B. Results of this effort are shown in Table 8. An <br />additional species, longnosed dace (Rhinichthys cataractae), was <br />observed during this effort in stratum B. No endangered fishes <br />were captured during post-runoff electrofishing. <br />2r <br />
