Overton has excellent CNBG.
Yours that I looked at did not look like any HBG variety .
I don't know from their site what they mean by some of the names they use or understand some of the stocking suggestions. They do however note in some the use of 2000-3000 BG per acre rather than 1000.
As per the consensus of this site I went with a lower stocking rate compared to what most hatcheries in the area were pushing.
I stocked at around 750 per acre and am giving them a year to get their numbers and size up before predators are introduced.
