Use of habitat heterogeneity in salmonid spawning habitat rehabilitation design
A shortage of salmonid spawning habitat on dammed and regulated rivers has led to the popularity of spawning habitat rehabilitation projects. Habitat heterogeneity is thought to be an important feature of aquatic ecosystems, but specific metrics for design and assessment are lacking. In August 2002, ~ 2,786 metric tons of spawning gravels and 7 large boulders were placed in a 155 meter reach on...
متن کاملSpawning Habitat Selection by Rainbow Trout in the Pere Marquette River, Michigan
We evaluated habitat features (i.e., substrate particle size, water depth, water velocity) at spawning redds and randomly selected reference locations (where spawning activity was not apparent) to determine importance of these features to rainbow trout (Oncorhynchus mykiss) spawning habitat use in the Pere Marquette River, Michigan, 1997 to 1999. Rainbow trout selected areas with small gravel, ...
متن کاملReproduction by June sucker in a refuge population: successful spawning in a lake habitat
—The June sucker (Chasmistes liorus) is an endangered lake sucker endemic to Utah Lake, Utah. As part of recovery actions, June suckers were introduced into Red Butte Reservoir, Utah, as a wild grow-out site. Since their introduction, June suckers have successfully reproduced in Red Butte Reservoir, producing a large population in this refuge. I used passive egg collectors (egg traps and nets) ...
متن کاملAtmospheric mercury deposition to Lake Michigan during the Lake Michigan Mass Balance Study.
Wet and dry mercury (Hg) deposition were calculated to Lake Michigan using a hybrid receptor modeling framework. The model utilized mercury monitoring data collected during the Lake Michigan Mass Balance Study and the Atmospheric Exchange Over Lakes and Oceans Studytogether with high-resolution over-water meteorological date provided by the National Oceanic and Atmospheric Administration (July,...
متن کاملSediment budget for salmonid spawning habitat rehabilitation in a regulated river
Bed elevation, feature adjustments, and spawning use were monitored at three Chinook salmon (Oncorhynchus tschawytscha) spawning habitat rehabilitation sites to measure project longevity in a regulated river. Sites enhanced with 649–1323 m of gravel lost from 3–20% of remaining gravel volume annually during controlled flows of 8–70 m/s and 2.6–4.6% of placed material during a short-duration (19...
