Abstract:
This study addressed the hypothesis that coho salmon (Oncorhynchus kisutch) learn and remember the odors of their natal environment. During one or more of the embryo, alevin, and early fry (first 14-day) stages, fish were exposed to the artificial odorant morpholine, natural odorants generated by conspecifics, or creek water. After an interval of at least one month the preference of fry for an odorant was tested in a Y-maze and compared to that of naive fry. Increased preference was interpreted as recognition. It is concluded that coho form long-term memories of at least some artificial and natural odors in early life, and that learning is not restricted to a brief critical period of development.
