Red Shiner (Cyprinella lutrensis) is a species of increasing management interest due to their negative impacts on fishes of high conservation concern. The release of YY Red Shiner into an invasive population may lead to their extirpation. Before our research, essential biological information about Red Shiner was lacking and the feasibility of producing YY Red Shiner was unknown. We have developed Red Shiner aquaculture protocols, conducted effective hormonal sex reversal treatments, uncovered the Red Shiner sex determination system, and performed verification crosses with YY Red Shiner broodstock. Our results are useful for the initial assessment of using YY Red Shiner to eradicate their invasive populations.
