Juvenile rainbow trout develop social hierarchies when held in dyads, and the development of socially subordinate (SS) and social dominance (SD) phenotypes in this context has been linked to specific changes in the hepatic energy metabolism of all major ...

Field and laboratory approaches to assess "estrogen disruption" in the brown trout "Salmo trutta" [PDF]
In recent years, the annual catches of brown trout and other native fish species have been declining in Switzerland about 60%. One hypothesis was that the reduced catch is linked to estrogen-active chemicals entering the aquatic environment via waste ...

TETRAZOLIUM OXIDASE POLYMORPHISM IN RAINBOW TROUT [PDF]
ABSTRACT Tetrazolium oxidase from the blood and liver of rainbow trout was found to be genetically polymorphic. The inheritance pattern of the liver enzyme was compatible only with a one locus-two allele hypothesis. The enzymes in the blood while having an electrophoretically identical polymorphism could differ genotypically from that of

Weight, Length, and Growth in Cutbow Trout (Oncorhynchus mykiss x clarkii)
Background: The cutbow trout (Oncorhynchus mykiss x clarkii) is a fertile hybrid of rainbow and cutthroat trout. Little published length-weight data is available for this hybrid, and a standard weight curve is not established. Eleven Mile Reservoir is

Structure of the rainbow trout metallothionein A gene [PDF]
To investigate the regulation of metallothionein-encoding genes in fish, we have isolated and sequenced the rainbow trout metallothionein-A-encoding gene (tMT-A) by polymerase chain reaction. This gene spans about 1.1 kb, consists of three exons and two introns, and has an A+T-rich 5'-region which contains a TATAAA signal, and two metal responsive ...

The effect of a trapping procedure on the stress response of wild rainbow trout
Fish traps are a common research and management tool in which fish are subjected to procedures that elicit a stress response in other contexts. The effects of trapping on the stress response of sexually mature, wild rainbow trout Oncorhynchus mykiss were

Ecological benefits and risks to native salmonids from beaver dam analogs
In degraded river systems, beaver dam analogs (BDAs) are an increasingly popular low-tech treatment used to reduce water velocity, increase floodplain connectivity, activate secondary side channels, and thus increase juvenile salmonid rearing habitat ...

Determination of Benzocaine in Rainbow Trout Plasma [PDF]
Abstract A liquid chromatographic method is described for analysis of benzocaine (BZ), a proposed fish anesthetic, in rainbow trout plasma. Mean recoveries of BZ from plasma samples fortified at 44–10 100 ng/mL were 96–100%. The method detection limit is 10 ng/mL, and the limit of quantitation is 37 ng/mL.

Genetic architecture of rainbow trout survival from egg to adult
Survival from birth to a reproductive adult is a challenge that only robust individuals resistant to a variety of mortality factors will overcome. To assess whether survival traits share genetic architecture throughout the life cycle, we estimated ...

Among the many threats posed by invasions of nonnative species is introgressive hybridization, which can lead to the genomic extinction of native taxa.
