Throwing back big fish
I didn't need to read that to know that, survival of the fittest is not new. People I fish with have said that for years. That is why I always encourage people to throw the larger more prized fish back. The smaller more plentiful fish taste far better anyway. Larger fish get large for reasons, maybe some of it is chance, but more often they are more fit genetically.
Thanks for posting though, food for thought.
