Available in PDF, EPUB and Kindle. Book excerpt: Biology of Stress in Fish: Fish Physiology provides a general understanding on the topic of stress biology, including most of the recent advances in the field. The book starts with a general discussion of stress, providing answers to issues such as its definition, the nature of the physiological stress response, and the factors that affect the stress response. It also considers the biotic and abiotic factors that cause variation in the stress response, how the stress response is generated and controlled, its effect on physiological and organismic function and performance, and applied assessment of stress, animal welfare, and stress as related to model species. Provides the definitive reference on stress in fish as written by world-renowned experts in the field Includes the most recent advances and up-to-date thinking about the causes of stress in fish, their implications, and how to minimize the negative effects Considers the biotic and abiotic factors that cause variation in the stress response

Mosser and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficacy of the methodology used for capture and upstream relocation of 26 adult spring-run Chinook salmon in Butte Creek, California in 2009 was evaluated. The fish had ceased volitional upstream migration prior to reaching their summer holding habitat. The purpose of the relocation was to move fish upstream of two water diversion dams and release them in a part of the stream from which they could presumably swim to cool summer holding habitat, then spawn in the fall. Fish were netted, transported by truck, given an esophageal radio tag/temperature tag, and released. Radio tagging proved to be a useful technique for determining the survival and movement of relocated fish and temperature tags provide useful information to determine thermal exposure and time of death. Twenty-three tags (88%) were recovered, compared with a 10% tag recovery rate for an earlier study using fin clips. Most tags were recovered within 3.5 km upstream and 1 km downstream of the release site. A single tag was recovered 6 km upstream. No fish were determined to have survived to spawn. Temperature tag data indicate that most of the salmon died within 2-6 days after the relocation operation. After preventative measures have been exhausted, future relocations efforts, in any setting, should consider (1) intervention as soon as fish cease volitional migration but before they are exposed to further deleterious conditions (2) monitoring environmental conditions to choose appropriate release sites (3) evaluation of disease transmission risk, and (4) handling practices that minimize potential stress due to air immersion and thermal shock.

Download or read book Straying of Late Fall run Chinook Salmon from the Coleman National Fish Hatchery Into the Lower American River California written by Gina R. Lasko and published by . 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.
