ABSTRACT

The objective 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.
