Methyltestosterone-treated immature male masu salmon Oncorhynchus masou par
r were attracted to both the urine of ovulated females and the ether solubl
e basic substances extracted from the urine, but not to immature female uri
ne. It is suggested that the male response to the sex attractant (releaser
pheromone) in the urine is under the control of androgens. (C) 2000 The Fis
