I worry about both cobia and blue marlin.

Currently the blue marlin tournaments here are still hanging up the big ones, at what looks like an alarming rate to me. Admittedly I have no good data, I hope I'm off the mark. Unfortunately moving to 100% C&R is not so simple. Aside from losing the spectacle and such, even if tournaments implement a good way to give more points for bigger fish, bringing a 600+ pound blue boatside and releasing it with enough energy to live is no easy task. I suppose even a 25% survival rate would be better than the odds of one that hangs up at the Wharf.
