I would NOT put it in!

I understand that the best time to stock a pond was five years ago, but I would try to resist the temptation to start a bass.

F1 fingerlings are expensive. I wouldn't want your single bass to slurp up the most aggressive of your F1s when THEY are out hunting.

(You are getting advice above from guys with far more expertise than I have, but that is just my two cents worth.)
