Salmon usually return to their natal streams to spawn, presenting a risk of breeding between close genetic relatives.
By reducing heterozygosity, #inbreeding can deplete the genetic variability of a population, affecting offspring fitness and survival Image

However, #salmons are externally fertilisers and females are polyandrous. So how do females control #fertilisation when this occurs outside of their bodies?
Can they somehow hamper fertilisation from their siblings?#evolution may have allowed such mechanisms Image
