The present study describes a rapid, simple and specific method to determine the sex of salmonid fish. This method is based on the detection by immunoagglutination of the serum vitellogenin of females in which oocytes are undergoing vitellogenesis. The application of this technique demonstrated the possibility of detecting vitellogenin in female brown trout as early as April and in all female Atlantic salmon captured in Brittany during the fishing season, between March and June.
