200 grass carp are VERY difficult to remove, they are wary, smart, hook shy, and big. There is no science to them unless someone would like to show my a scientific journal article it's all anecdotal, but I could be wrong. Nobody can even tell me how long they live, I hear 5 years, 10 years, 15 years, 20+ years who knows. I hear they become less efficient as they age is that proven. I would like to know of some lakes where Grass Carp were introduced and the fishing got better for the next 10 years and how many were introduced, the BOW size and the type of weed they were put in to control, based on what you hear and when you talk to fisheries experts like I did hear with Indiana DNR they are a pure disaster.
