Endogenous and Environmental Control of Smolt TransformationThis chapter considers endogenous and environmental factors that influence smolt transformation. It also provides evidence that an endogenous developmental program, mediated by hormones and entrained by the annual cycle in daylength, regulates the smoltification process.

Imprinting to Olfactory Cues: The Basis for Home-Stream Selection by Salmonoil and vegetation of the drainage basin, each stream has a unique chemical composition and, thus, a distinctive odor; (2) before juvenile salmon migrate to the sea they become imprinted to the distinctive odor of their home stream; and (3) adult salmon use this information as a cue for homing when

Thyroid Activation of Olfactory Imprinting in Coho Salmons at the time of smolt transformation (Scholz 1980). Our overall plan for testing this hypothesis was to inject TSH or ACTH into pre-smolt coho salmon while simultaneously exposing them to a synthetic chemical, either morpholine or phenethyl alcohol. Ten months later behavioral tests were performed
