Pond Boss Forums INTRO Questions & Observations Crawfish as weed control

I have too many northern virile craws in my little pond. I would like some more plant life and less muddy waters Over the course of two summers I stocked about 300 juveniles with the second summer being when I stocked my game fish. This allowed many of the craws to outgrow the mouth gape of my HSB and reach adulthood. This is the main reason I have too many of the large craws. I don't see many juveniles which makes me believe they are feeding my HBG and I wonder how good the 2-3 pound HSB are at feeding on the adult craws. I'd bet a LMB population would put them on the endangered list, but I'm sticking with my HSB.
