These fish, commonly named McCloud River 'redband' trout, survive in their most primitive form in a small, spring-fed stream, Sheepheaven Creek, in the upper McCloud River drainage. Turn-of-the-century fisheries ...

The introduction of alien predatory fish such as rainbow trout ( Oncorhynchus mykiss ) can have a significant effect on indigenous communities altering the structure and dynamics food webs. Quantifying trophic niche utilised by species is therefore important to aid our understanding how their feeding strategies might establishment, define functional role inform potential impacts. This study ass...

Increasing temperatures and changes in food resources owing to climate change may alter the growth and migratory behavior of organisms. This is particularly important for salmonid species like Oncorhynchus mykiss, where some individuals remain in freshwater to mature (nonanadromous Rainbow Trout) and others migrate to sea (anadromous Steelhead). Whether one strategy is adopted over the other ma...
