Distribution of spawning activity by anadromous fishes in an Atlantic slope drainage after removal of a low-head dam
In 1998, the Quaker Neck Dam was removed from the Neuse River near Goldsboro, North Carolina, restoring access to more than 120 km of potential main-stem spawning habitat and 1,488 km of potential tributary spawning habitat to anadromous fishes. We used plankton sampling and standardized electrofishing to examine the extent to which anadromous fishes utilized this restored spawning habitat in 2003 and 2004. Evidence of spawning activity was detected upstream of the former dam site for three anadromous species: American shad Alosa sapidissima, hickory shad A. mediocris, and striped bass Morone saxatilis. The percentages of eggs and larvae collected in the restored upstream habitat were greater in 2003, when spring...
Minimum Flow Recommendation For Passage Of Colorado Squawfish And Razorback Sucker In The 2.3-Mile Reach Of The Lower Gunnison River: Redlands Diversion Dam To The Colorado River Confluence
The 2.3-mile reach of the Lower Gunnison River between the Redlands Diversion Dam and the confluence with the Colorado River is important habitat for Colorado squawfish and razorback sucker and is designated critical habitat for these two fishes. The purpose of this study was to recommend a minimum streamflow for passage of sub-adult and adult Colorado squawfish and razorback sucker during low-flows in this reach.
