Well I've certainly caught 3" young of the year fingerlings of LMB in my pond before on various baits and sometimes flies.

Can't say it was much of a rush as they were not the first fish in a new pond.

It could be interesting to see what hits some small bait like a maggot on a small hook, however, you could be stressing the fish.

There is a discussion happening about pellet trained LMB vs. non-pellet trained LMB on this board. Several of the replies discuss fish getting "hook shy" in smaller bodies of water.

So maybe you'd have to weigh the pros & cons of trying to fish now vs. in a year or so.
