of this project was to augment roe production in pink
salmon hatcheries by applying gynogenesis and masculiniation
to brood stocks to develop all-female milt for fertilizing
hatchery-reared eggs, thereby producing all female offspring.
This project applied practical fish gender-control technology
to Pacific salmon. Successful control of salmon gender
on a production scale requires application of two procedures,
namely, gynogenesis and sex reversal. This project had
good success in applying gynogenesis techniques to Pacific
salmon, in particular pink salmon (Oncorhunchus gorbuscha)
and coho salmon (O. kisutch). The project had
minimal success in applying sex reversal techniques to
pink salmon but provided a basis for ongoing development
of more successful techniques after the end of the project.
