Though I hate to admit it I’m somewhat in agreement with these animal rights people.Why kill the animal if your not going to consume it or donate it to someone who will.
Though at the same time I think to become as large as that Marlin did he had to consume a huge amount of smaller fish who will now stand a better chance of survival since their predator is gone.
That fish was worth big bucks. It was consumed. It probably brought in well over $25K..
