It sounds like it's from that website that uses artificial (non)intelligence to populate the data fields. I forget the name of the site, but it's downright laughable.Not sure who wrote that small summary, but I'm afraid they are mistaken.
There are no Pumpkinseed in NS and being a landlocked lake with a dam & impassable waterfalls, there would be no Stripers. Not too sure on white perch in there, but there are some beautiful brook trout. As long as the weather cools a bit, they should be available, mainly near the mouths of the brooks.
