چکیده
of the wildlife resources and a producer of additional fish and game via hatcheries and habitat management. Sometimes these roles of commodity versus stewardship are at odds. Such is the case where the DWR stocks exotic species such as rainbow trout to provide recreational fishing while attempting to conserve populations of native species such as the cutthroat trout. Cutthroat are the only trout species (other than mountain whitefish) that were here when white settlers first arrived. All others have been introduced, including the rainbow trout. Cutthroat trout readily hybridize with rainbow trout, diluting their genetic purity. This can make them less able to survive in the habitats they evolved in by altering factors such as spawning times, escape behavior, feeding habits, growth rates, disease tolerance, and cryptic coloration. However, rainbow trout are a great sport fish, displaying faster growth and more fight than cutthroat trout. Providing rainbow trout to anglers that have become accustomed to them is desirable, but so is the preservation of cutthroat trout, a fine sport fish itself. Also, cutthroat conservation is needed to prevent their listing as a threatened or endangered species.

The effects of Myxobolus cerebralis on the physiological performance of whirling disease resistant and susceptible strains of rainbow trout.
The development of rainbow trout Oncorhynchus mykiss strains that are resistant to whirling disease has shown promise as a management tool for populations in areas where Myxobolus cerebralis is present. However, the physiological effects of the disease on characteristics necessary for fish survival in natural river conditions have not been tested in many of these strains. Five rainbow trout str...

A nested polymerase chain reaction for the detection of genomic DNA of Myxobolus cerebralis in rainbow trout Oncorhynchus mykiss.
A nested polymerase chain reaction (PCR) test was developed to amplify a segment of the 18S rRNA gene from Myxobolus cerebralis, the agent causing whirling disease in salmonid fish. The PCR amplifies a 415 bp amplicon that was identified by dideoxynucleotide terminated sequencing to be identical to the known 18S rDNA sequence of M. cerebralis. There was no amplification of genomic DNA from 4 ot...

Monoclonal antibody B4 (mAb B4) was previously developed to the myxozoan parasite Tetracapsuloides bryosalmonae Canning, Curry, Feist, Longshaw et Okamura, 1999, the causative agent of proliferative kidney disease of salmonids, Here we describe the reaction of mAb B4 against Myxobolus cerebralis Hofer, 1903, the parasite that causes 'whirling disease' in salmonids. Tissues examined were collect...
