I agree with you that LMB do get less aggressive the bigger they get. However with the Tigerbass which is a crossbreed between a Northern and a Florida bass it is suppose to stay just as aggressive at 8lbs as it is at 1lb. Adding another type of bass is not what I want to do.
The Tiger's do chow down on the shad. There is so much forage food in the BOW that they do not have to stay aggressive for food. IT is right there for them. Which is how we built the lake and wanted it to be so that we could grow Trophy LMB. We went with Tigerbass because of all of the good things that we had heard about them gaining a lot of weight quickly and staying very aggressive no matter there size.
With food being so plentiful in the BOW is why I have been thinking about adding sterile Striped Bass to the lake to give the Tigerbass some competition and forcing them to have to compete for food.
