Sorry, don't buy it. Removing larger fish does not stunt their growth. The genes don't change because you took a big fish. The fish are smaller because there is not enough fatty foods for them to eat. They are eating small lobsters (which is hurting that fishery) and craps and low cal fish. They need high fat content fish...bunker, giant sand eels, and lots of herring and macs to grow big.
IMO taking the big fish does hurt the potential population because a giant bass has lots of eggs. BUT I would rather have lots of young healthy breaders then one ol bitch that could die during the spawn and wipe out your main breeder . More is better. One could also use the pollution arg...that the old fish will have a higher heavy metal content and this old cow will be producing poor quality eggs...
IMO all you have to do is keep the lower limit at a point where every fish has a chance to spawn a couple times, keep the water clean and provide enough food for them and there will be enough bass forever.
Making the limit more complicated will not solve anything. It is not policed now...what makes you think someone is going to release a gut-hooked 50# cow? Get real.
