EVIDENCE OF AN OLFACTORY IMPRINTING WINDOW IN EMBRYONIC ATLANTIC SALMON
Our investigation sought to determine whether embryonic Atlantic salmon have the ability to imprint upon odors in order to locate natal streams later in life, as well as whether rearing and imprinting fish in different water sources has an impact on that ability. Using behavioral and physiological experiments, we demonstrated that adult Atlantic salmon show a preference for the water to which they were imprinted upon in early life stages. Additionally, we found different water sources impacted the efficacy of this imprinting. These results, indicating that water source during development may affect the ability to imprint, have implications for hatchery programs that often incubate salmonids in well water during the alevin life stage. This study provides a novel example of not only the ability for Atlantic salmon to imprint at embryonic life stages but also how that ability may be affected by environmental factors.
