I think it's fair to say that it's legit feedback to express a conservation ethic and I'd like to see all bill fish released. Having said that and being a bil fish angler I will say that I have seen some blues dead at the boat. Not that we did not try every single thing possible to land it quickly and release them, but sometimes things happen and the fish dies. In that case we often send it back for food for the ocean. Hanging a bill fish at the dock outside of a tournament on the east coast is not something you see a lot and I'm not a big fan of it. Having said that I can understand why someone who visits the coast would want to have their picture taken with the fish, people dream of catching billfish much less a decent blue marlin.
I can not comment on this particular case of what happened and not sure any of us should jump to any conclusions since we do not really know what happened. If the fish died at the boat and the guys wanted to have their picture taken then it's understandable. I'd hope the fish was not sent to dumpster, but was fileted to feed someone.
Sometimes things on the internet can come across in ways we all do not intend. I think the message here is that we should be conservation minded when it comes to all fish and especially when it comes to billfish. It does not mean we can not keep fish to eat or anything like that, but rather to just have conservation and what messages our actions send to the broader public.
I think if we all take a deep breath we can see how hanging billfish at the dock outside of tournaments could start to set a negative example at some level. If we do not think with a little conservation in mind we are not going to have fish for the future and then we all loose the game, not something any of us want.
