title: Changes with age in total brain concentrations of biogenic amine neurotransmitters in coho salmon (Oncorhynchus kisutch Walbaum).
abstract: Whole brain content of several biogenic amines was determined in two age groups of coho salmon (Oncorhynchus kisutch Walbaum). Brains of presmolt salmon (about 5 months old) were compared to brains of homeward migrants (4 years old). Levels of dopamine and serotonin were significantly higher in the homeward migrants.
