That's a lot of carp. I remember seeing a carp feeding where they threw popcorn into the water and these carp were on top of each other and all snaked up. It was freaky and unsettling.
As far as invasive species, I'm neither a lover or hater. Correct me if I'm wrong but aren't these coho, chinook, and steelhead salmon in LM an invasive species to these waters? I'm not an indigenous fish expert but from what I understand, these salmon were introduced here after the lake trout population crashed.
The charm of fishing is that it is the pursuit of what is elusive but attainable, a perpetual series of occasions for hope. -John Buchan
