Post-Runoff Sampling. During post-runoff sampling in July, two adult Colorado squawfish were the only native fish caught in Gardner Pond which was 1% of the 137 total fishes collected. These two fish were caught in the connection channel between the pond and river. In Hotspot Pond, the only native fish caught were two juvenile flannelmouth sucker that comprised 2% of the 99 fish collected (Figure 4). The most common nonnative fishes captured in Gardner Pond were black crappie (24X), common carp (20X), white sucker (21X), and black bullhead (15X). In Hotspot Pond, the four most common caught fishes were black bullhead (28X), white sucker (21X), largemouth bass (19X), and common carp (18X; Table 3). Gear Type vs. Species Selectivity Relative abundance was used to describe the species collected by each gear type (Appendix C; Tables C.1.-C.3.). Of the 448 fish collected with electrofishing from both ponds during the three periods sampled, the most common fishes captured numerically in descending order were common carp (64X), largemouth bass and black bullhead (12% each) and green sunfish (4). Of the 1,348 fish collected with trap nets, the most common species captured were black bullhead (34X), white sucker (24X), black crappie (12X), and flannelmouth sucker (8X). Of the 389 fish collected with trammel nets, the most common fishes captured were white sucker (39X), flannelmouth sucker (23X), black bullhead (20X), and common carp (7X). An attempt was made to determine if one gear type was more selective in capturing certain fishes. Each of the three different gear types used to capture sub-adult and adult fishes appeared to select for certain species. Electrofishing selected for sub-adult and adult carp, largemouth bass, and black bullhead (Table 4; Figure 5). Trap nets captured three times as many fish as either electrofishing or trammel nets. Trap nets selected for black bullhead in addition to white sucker, black crappie, bluegill, and green sunfish. Trammel nets appeared to select more than electrofishing for black bullhead and white sucker. Trap and trammel nets were similarly selective in capturing native fishes such as flannelmouth sucker, bluehead sucker, roundtail chub, and Colorado squawfish. Fish Recaptures One adult Colorado squawfish (PIT-tag no. 1F413A0066), initially captured in Gardner Pond 11 April, was recaptured twice in Gardner Pond, once on 15 April and again on 11 June (Appendix B; Table B.1.). Of the 2,152 sub-adult and adult nonnative and native fishes that were fin- clipped in both ponds during 1996, 370 fish were recaptured. Fifty-six percent of the fish were recaptured during the first sampling period, pre-runoff; 31% were recaptured during the second sampling period, runoff; and 13% were recaptured during post-runoff. Numerically, white sucker (127), and black bullhead (76) were the most common fishes recaptured which was 27% and 13%, respectively, of the total number marked (470 and 575) for each of these two species. Of the 90 largemouth bass captured and marked, 21% were recaptured. Approximately 112 fishes that were initially marked in Gardner Pond were 14
