While trying to catch some Tilapia this past weekend in my ponds, I accidently hooked a three year old grass carp on a live worm. It actually bit the worm. What a fighting fish! If you could catch those with any degree of reliability, I'd soon forget about LMB and HSB and stock grass carp. Estimated weight 10 to 15 pounds...but I had to break him off on the light tackle.
