Book excerpt: Salmon specialists throughout the Pacific Coast indicate that the winter-run Chinook salmon is restricted to California's Sacramento River system. The characteristics and habits of the race are unique in the following respects: Fresh-water holding period, December to April; spawning period, April into July. The up-migration is concurrent with the late segments of the fall run, but the adults are distinguishable by the green condition of the gonads. The down-migration is concurrent with that of the spring-run fry, but the migrants are 2-inch or larger fingerlings. Evidence is lacking to determine whether there is an earlier down-migration of fry. The race appears to hold great promise as a stock to be introduced into areas where May-August temperatures are 42.5 degrees - 57.5 degrees F., for it supports superb angling during the fresh-water holding period. Water temperatures in May through August are seen as the factor limiting the natural extension of the range of the race.

This book was released on 2012 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon (Oncorhynchus spp.) are generally anadromous fishes that spawn in fresh water. When young salmon have grown and matured to what is called the smolt stage (ocean ready), they move into the ocean to mature and grow into adulthood. When they have reached sexual maturity, they return to fresh water to spawn and then die. Salmon typically home to their natal streams when returning to fresh water to spawn. Straying, however, is a natural behavior for a small fraction of individuals in a population, and may even have an adaptive advantage under some circumstances. Straying can also occur as a result of various factors including natural habitat disruption, modification of the watershed, or human intervention in salmonid reproduction. In the winter of 2006/2007, tens of thousands of late-fall-run Chinook salmon (Oncorhynchus tshawytscha) reared in the Coleman National Fish Hatchery, a US Fish and Wildlife Service facility on Battle Creek in the upper Sacramento River basin, were released at several downstream locations as part of a Sacramento-San Joaquin River Delta survival study. Two years later, in the winter of 2008/2009, at the end of the annual Department of Fish and Game lower American River escapement survey for fall-run Chinook salmon, a new pulse of fish was found to be spawning in the American River. These fish turned out to be stray late-fall-run Chinook salmon from the Coleman National Fish Hatchery, spawning in the American River where the fall-run Chinook salmon were completing their spawning run. Late-fall-run Chinook salmon have not been known to spawn in the American River and understanding the reason for this unusual behavior was the basis for this project. Currently the only run of Chinook salmon in the lower American River is the fall-run. The Department does not want late-fall-run Chinook salmon to establish themselves in the river because of potential disruption of fall-run Chinook salmon nest success due to an overlap in run timing, potential interbreeding, and limited available spawning habitat. This study was based on the hypothesis that salmon released in close proximity to the mouth of the American River are more likely to stray into the river during their return spawning migration than fish released farther from the river's mouth. Coded-wire tag inland return data from for the 2006 brood year of late-fall-run Chinook collected from 2007/2008 through 2010/2011 were used for this study. The tags were collected primarily from salmon found during river escapement surveys and those that returned to hatcheries in the Sacramento River watershed. The return data were analyzed using Chi-square statistical analyses to determine if there was a difference in the number of salmon straying into the American River with respect to the distance they were released from the mouth of that river, and a Spearman noncollated rank analysis was used to describe the overall relationship between release distance from the American River and percent straying into the river. Results indicated that straying did increase with proximity of release location to the mouth of the American River and with respect to downstream releases in general. No salmon released in the vicinity of the Coleman National Fish Hatchery were recovered in the lower American River. This study indicates that release location should be carefully evaluated if future downstream releases are conducted by Sacramento River watershed hatcheries.

Download or read book Using Thermal Tracers to Determine Fall run Chinook Spawning Site Selection Preferences on the Lower American River California USA written by Michael Edward O'Connor and published by . This book was released on 2014 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal tracers were used to characterize two adjacent salmonid spawning habitat sites on the Lower American River: a natural spawning feature heavily used by fall-run Chinook salmon and a less utilized site that was enhanced with spawning gravels. A network of monitoring wells were installed at the sites to monitor stream and subsurface water temperatures coupled with pressure to determine subsurface flow characteristics. Data was qualitatively analyzed to investigate differences in subsurface flow paths using temperature gradients. Additionally, hydraulic conductivity and seepage discharge values were estimated at the monitoring wells using 1DTempPro, a recently developed graphical user interface for VS2DH that facilitates the one-dimensional energy transport model. Qualitative and quantitative results show clear differences between the two study sites. The natural spawning site showed more temperature variation with depth from surface water temperature while the enhanced site's subsurface temperatures closely followed stream temperature variations. Furthermore, estimated hydraulic conductivity and specific discharge values at the natural site were one to two orders of magnitude lower than those estimated at the enhanced spawning site. Specific discharge values also showed a mix of upwelling and downwelling conditions at the natural spawning site while downwelling dominated the enhanced spawning site. Qualitative and quantitative results suggest spawning fall-run Chinook salmon in the Lower American River prefer spawning features that have a mix of downwelling and upwelling flow conditions with relatively lower hydraulic conductivity values which allow adequate mixing of groundwater and surface water in the subsurface. These conditions create a temperature signal in the shallow subsurface that is distinctly different than the surface water temperature signal. This study also shows the utility of employing heat as a tracer to characterize spawning features in streams. Spawning habitat enhancement projects are likely to increase in the future in response to salmonid population vulnerability in rivers. Therefore, qualitative and quantitative evaluation of habitat quality before and after project completion is crucial for improving this restoration technique. Thermal tracers provide a relatively simple, low-cost, low-maintenance method for determining key habitat characteristics over long time scales and at potentially high spatial resolutions.
