When you stock LMB in May (as suggested in the south), are those LMB fingerlings spawned the Feb/March of the same year?

If so, how can you get fingerlings in winter? I'd assume that if you stocked in fall you'd also get the growth from May through October. So, it would cost more to stock the same number of fish in the fall because they are bigger but you'd have (at least) the same growth you'd have had if they were in your pond...

Does any of that make sense?
