You are probably correct but the same argument works against all the anti-culling people. Most of us are not bioligist, and cant really make an educated guess on the subject, we do have our observations but they most likely are small windows into a large ecosystem with tons of variables. Also, Large mouth Bass are not native to southern california so to "Let Mother Nature Figure it Out" doesnt really work, because it is a non-native fish eating other fish which are not normally native to there habitat. Many of the ecosystems as a whole are not balanced anyways and never will be. Because of this man needs to get involved and create some sort of equilibrium, just like a lot of people who used to slaughter the striped Bass so they would eat all the young LMB or trout.
Some of the measures i have read others say in this thread make sense like selective culling. Like the Halibut and white sea bass regulations in California, that is working.
I cant wait for the flack i will get for this post. By the way i have never taken a LMB and only practice C&R because if i want to eat fish i go to a restaurant or buy it from the store.
