In trout farming males exhibits lower growth rate and precocious sexual maturation in contrast to females.
Since these traits are detrimental for intensive production, all females populations are most appreciated by fish farmers.
Molecular markers sex-specific have been developed for rainbow trout that can be useful to diagnose the phenotypic sex of individuals.
We evaluated the use of two SCAR markers (OmyP9 & Omy163), which show polymorphisms between males and females in rainbow trout as a diagnostic test for sexing farmed trout.
Adult trout (n = 131) were genotyped to assess the association of the SCAR markers with phenotypic sex. To evaluate the correct performance of the SCAR marker in sex diagn...
