By following a few simple rules you can be certain that released fish will live to be caught again. Remember that a fish that appears unharmed when released may not survive if not carefully handled. Here's what you can do and methods to work with to ensure the well-being of the fish that gave you so much pleasure when it was on the end of your line.
Time is of the essence.
Play and release fish as rapidly as possible. A fish out of water will suffer brain damage due to loss of oxygen. A fish played gently for too long may be too exhausted to recover. Keep the fish in the water as much as possible. A fish out of water is suffocating and, in addition, is many times heavier.
