When we take out the aggressive, fast growing, easy to catch fish we are in fact doing something along the lines of selective breeding. By eliminating those genes that have a higher potential to reach the full size of any one species and leaving the runts to reproduce.
But, that doesn't happen in a natural system. Even when we harvest those "aggressive, fast growing, easy to catch" fish. Think about it for a minute. When are those fish caught? Have they already had the chance to pass along their genes?
the answer is yes. Even when harvesting large fish, they have still had the opportunity to pass along their genes. We have not eliminated their genes from the pool.
Unless you are harvesting the "aggressive, fast growing, easy to catch" fish prior to them becoming sexually mature, then your argument doesn't hold. They are still mixing those genetics and passing them along to future generations of fish.
Harvest of the large fish doesn't breed out the large genes. Large fish have already passed those genes along.
