It is still my opinion that netting is very bad for fish. If you plan to net all of your fish, get one of those rubber mesh nets. I try to hand land as many of my fish as possible (wet your hands first). True, I have lost some nice fish on the count of this, but then I just have to swallow my ego and consider what is best for the fish. The over the gill grab works well for walleyes up to 9 lbs, then it is tough to get your hand around that far. Once you get the fish in the air, you can slip a couple fingers under the gill plate and get the mouth opened up. Put you thumb on the other side of the 2 fingers you have inside (do not go up too far or you will enconter the gill rakers), (this is sometimes called the Leech lake lip lock). If you can do all of this while the fish is still in the water in the net, so much the better. Once you have the hooks out, you can put your other hand under the belly for a photo if you wish.
If the fish does not recuperate quickly and swim right away, you will need to revive it. You can grab the thin part above the tail and move the fish back and forth in the water. If the fish does not open up its mouth, the same gill grip can be used with the tail grip to open the fishes mouth. It is better to move the fish in a forward direction or face it into the current. The fish will begin to squirm when it has recovered some of its energy.
Bass can be grabbed by the lower jaw, be careful of the hooks. Some people grab smallies by the belly.
Northerns under 10 pounds can be grabbed across the gill plates, over 10 lbs, you can slide up under the top of the gill plates and find a good hold there. Wet your hands first.
You have to have an in control attitude. You need to show the fish who is boss. If the fish feels you let up at all, it will thrash and that is when you and the fish can get hurt.
