The key to releasing these fish is get the hooks out quickly and get them back in the water. Once back in the water, give them the opportunity to revive themselves for as long as they need before releasing them from the boat. If you need a picture take it after they are revived instead of before to eliminate that extra stress on them. I use my bog grip to handle them and get the hooks out. I have a rope , lanyard and Fish Grip set up on both sides of my boat. I then use the Fish Grip, release my Boga (too expensive to loose) and get them immediately in the water on the side of my boat out of the way. I can then get back to fishing quickly (the priority because I have active fish) without hanging over the side trying to revive the fish. When the fish is swimming good and fishing activity allows, it gets released.
For all of the time and money we spend with Pen Rearing to improve our Fishing, successfully releasing a fish (that has made it to become a catchable fish) is the single largest thing any of us can do to support the Fishery.
Here is a short video from my boat last August on staging kings.
