Natural isotope markers in salmon

摘要: To optimize conservation and restoration strategies for fish stocks it is important to identify the rearing habitats that produce most successful individuals. However, tracking millions of migratory through multiple life stages seems be impossible using conventional techniques. Using differences in ratio stable isotopes strontium (Sr), found naturally stream water, we have been able distinguish juvenile Atlantic salmon (Salmo salar) from eight ten sites studied Vermont streams. This demonstrates potential environmental signals determine which originate, should help guide activities.
