We raised F1s for 10 years. There is a good reason for our discontinuation of this program. It is called outbreeding depression. There was a talk about outbreeding depression in largemouth bass at one of the Pond Boss conferences that, along with our experience in the field, influenced me to halt my breeding program. Basically, once you have Florida/Northern bass interbreeding, you may go down a road of irreversible decline, or be required to manage by adding pure genetics on regular basis.
Pure genetics breed true. Avoid possible inbreeding by supplementing with more pure genetics down the road.
