You'd have to net her out into a bucket or large enough container to get two hands in. Its basically holding the fish with your hands (or in the net, but i find it easier without the net) and not covering it's gills, and putting her head underneath the water and gently opening her lower jaw open with your index fingernail. Then you bob the head up and down in the water to get the fry out. If you strip after two weeks, the fry are usually free swimming so they might try to swim back in.
