A new step-by-step procedure developed by the scientists makes it easier to separate fish by gender for growth performance, physiological studies and to manage broodstocks for reproduction and genetic selection.

Physiologist Brian Shepherd and his colleagues at the Agricultural Research Service (ARS) Dairy Forage and Aquaculture Research Unit in Milwaukee, Wisconsin, developed the systematic method to segregate yellow perch females from males during early growth stages. Because females tend to grow faster and larger than males, females could often be mistaken for males when being selected for genetic improvement prior to reproductive maturity. Previously, it was extremely difficult to identify gender until fish matured (up to two years).  Read more …
