Several species, including the largemouth bass, black bullhead, blacknose shiner, common shiner, fathead minnow, and redbelly dace exhibited increased abundances during some of the high discharge years in 1985-1987 but were less abundant from 1988 to 1992 [ILLUSTRATION FOR FIGURE 3 OMITTED].
Largemouth bass, black bullhead, black-nose shiner, common shiner, and fathead minnow all tended to be more abundant in the stream from 1984 to 1987 than from 1988 to 1992.
Colonization of the stream in May, for instance, was predominantly by fish [greater than]age I, especially among those species (e.g., black bullhead, fathead minnow, common shiner, and brassy minnow) that were abundant during the high discharge conditions of 1985-1987.
Age 0 fathead minnow, common shiner, and blacknose shiner were never captured in Gould Creek during the entire 10-yr period.
This is probably why basic differences occurred in the composition of fish moving downstream out of the larger and deeper Beaver Lake (e.g., large-mouth bass, black bullhead, common shiner), relative to those moving upstream (e.g., brook stickleback, blackchin shiner, and redbelly dace) out of the smaller and shallower ponds on Gould Creek.
Chironomids dominated the diet of common shiner (60.6%) and cutlip minnow (54.7%) at the upriver site (Figs.
Diet overlap was only significant between common shiner and cutlip minnow ([C.sub.[lambda]] [bar.x] = 0.88) (Table 2).
Feeding activity by common shiner and cutlip minnow was lowest at night (i.e., 2400 h-0400 h) (Figs.
Inter-specific associations relative to the upper river cyprinid assemblage (i.e., common shiner, cutlip minnow, fallfish) were previously unreported.
Of the four species examined, the most extensive information on diet exists for common shiner and spottail shiner.
Moreover, at the upper Salmon River site where three species occurred sympatrically, fallfish and common shiner, were, on average about 20 and 15 mm larger than cutlip minnow.
There were considerable differences in [r.sup.2] values (i.e., models constructed with lateral line scales were better fitting than models constructed using non-lateral line scales) for several species [e.g.,
common shiner, northern pike (Esox lucius), and percids], but for other species (e.g., carp, centrarchids and freshwater drum) [r.sup.2] values differed only slightly between models (Table 1).
Based on videographic observations they actively avoided predation by Smallmouth Bass (Micropterus dolomieu), and were associated with Rock Bass (Ambloplites rupestris), Pumpkinseed (Lepomis gibbosus), and Common Shiners (Luxilus comutus).
In 2015 mobile underwater cameras recorded spawning among several Cyprinid species including Rosyface Shiners and Common Shiners, but not Silver Shiners.
"This reach is dominated by a good mix of minnow species - primarily fallfish and
common shiners - and they support both redbreast sunfish (up to 8 inches) and smallmouth bass (up to 12 inches) in considerable numbers," Richards said.
