The HSB were in all around the 4-5" size range.
The originally stocked group of 300 YP were 3-4" last fall from Fenders located in OH. They are now easily 5-6" so I would say that there is a good possibility they could spawn this spring which is exciting.
The 100 YP I most recently stocked were only about 3-4".
How large of a YP will the HSB eat?
