What is a one-sentence summary of the following article?
Squeeze the fish's body gently with your whole hand, applying equal pressure all the way around so it doesn't slip out on you. Keep your grip fixed, only making minor adjustments if necessary. As long as you maintain a safe hand positioning while holding onto the catfish, you shouldn't have to worry about getting pricked. The combination of slick skin and caked-on mud from the river bottom can make catfish particularly tough to handle. A fresh catch may twist and wriggle suddenly in an effort to free itself. If you get caught off guard, you could lose it. A full-grown catfish can get very heavy, so keeping another point of contact on the tail section will make it a lot easier to lift. A two-handed grip will also allow you to control a fresh catch if it begins thrashing around. Make sure your support hand stays far away from the spines, as well. Whether it's destined for an onboard cooler or you've decided to return it to the deep, you'll need to exercise caution when letting go. Lower the catfish so that it's as close to the water as possible. Loosen your grip in one smooth motion, being careful not to let your hand brush along the fish's back. Instead of attempting to toss the catfish away from you, let it slip beneath the surface nice and easy and get moving on its own. Since your fingers will be behind the spines, it will simply swim harmlessly away.
Lift the catfish. Use your other hand for support. Release the catfish cautiously.
