Natural variation may help decide which rainbow trout strains are likely to survive worldwide global warming, according to a new study. The findings will be presented today at the American Physiological Society's (APS) Comparative Physiology: Complexity and Integration conference in New Orleans.
The increasing temperatures and resulting lower underwater oxygen levels linked to climate change will likely affect the habitats of cold-water fish such as rainbow trout. The resilience of this species to changes in its environment will ultimately help it survive the significant warming of its home tributaries.
Researchers - University - British - Columbia - Strains
Researchers from the University of British Columbia studied three strains of rainbow trout, one that originated in California and two native to Canada. They found that young fish (called "fry") from California were able to tolerate higher water temperatures...
