Only if you say so, the one lonely male GSF we had in our pond many years ago was removed by my brother. As of last summer only one of his hybrid offspring is still known to exist in our pond, according to my brother-in-law he was 11-1/4" long last July.
Now if I remember right, jeffhasapond also has a substantial amount of aquatic vegetation in his pond which will have an influence on the efficacy of predation relationships.
