Provided you're sampling some better WR YP you're fine - I've had really poor growth rates on some YP also - I don't lose any sleep provided I'm still sampling solid YP. Start keeping WR records on fish you sample so you understand your fishery dynamics which in turn dictates management strategy. Do you witness YP feeding?

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
