Research Abstract

We analyzed morphometric change in the quantity of olfactory receptor neurons during life history in chum and masu salmon. The number of olfactory receptor neurons s is synchronized with the body size throughout its life history, including the imprinting-related periods (both downstream and upstream stages). In addition, thyroid hormone receptor beta was characterized in the olfactory epithelia of chum salmon by molecular biological and histochemical techniques.
