With the increased popularity of fishing, there is a great pressure upon the fish resource of the Sierra. We have tried to assist the fish resource by developing fish hatcheries and planting trout throughout the Sierra. The result has been a further reduction in the numbers and quality of wild trout. Hatchery trout compete for the available food within the stream, often they do not have the ability to survive past one season. The current trend is to eliminate fish stocking programs and enhance the wild trout stocks. This cannot be accomplished without effective Catch and Release Techniques using the following elements:
- Use Barbless Hooks
- Play the fish quickly
- Remove the hook and handle the fish gently
- Revive and release the fish
Use Barbless Hooks
Barbless Hooks are much easier to remove from a hooked fish. Using barbless hooks will not reduce your ability to land the fish once you learn how to apply proper line pressure. You can purchase flies that are barbless, tie your own, or mash down the barb with your hemostats. Many areas require barbless hooks. If you use the mashing technique, test it with a piece of tippet across the mashed barb. If the barb still catches the tippet, it is not legally barbless.
Play the Fish Quickly
Once you hook a fish, the fish will fight to get away. This exertion builds up an oxygen deficit with the fish which causes stress on it's organs. If you fight a fish for too long a period the stress levels will become too great to recover and death will occur. Things that you can control to reduce stress is to choose the use of a rod, line, and tippet that will allow you to play the fish for a shorter period of time. For instance, using a 5 weight rod with a 4X leader will allow you to bring a sizable fish to the bank much faster than a 2 weight rod using a 7X leader. If you feel that the fish you are going to catch will reach a certain size, choose a larger rod and rig rather than a lighter one. As you play the fish, once the fish's head comes out of the water and it no longer sprints off or makes a run, it is just fatigued enough to bring in and let it go.
Remove the hook and handle the fish gently
Once the fish is brought to the bank, leave it in the water to remove the hook. Keeping the fish in the water will help replenish lost oxygen. Usually you will hook the fish in the jaw and using a hemostat will allow you to grip the hook and make a quick removal. At times, the hook may get swallowed or get hooked in a more sensitive area. In this situation, cut the tippet close to the hook and the hook will rust off within a short period of time. If blood is coming from the gill areas, the fish will die shortly and you may prefer to take the fish home for consumption. Unfortunately, some regulations demand that the fish be released immediately.
Fish have a protective slime coating that protects them from fungus and parasites. If this slime coating is removed, the fish will have difficulty in surviving. Wet your hands prior to picking up a fish and, if you use a net, use a net with a seamless mesh and a shallow bag. Many times, these nets are marketed under a "Catch and Release" moniker.
You can temporarily immobilize larger trout or other species by gently grasping them around the belly and turning them upside down. Then use the other hand to remove the hook. Never squeeze a fish, you may damage it's internal organs, particularly the air bladder that it uses for buoyancy and to keep itself upright.
Revive and release the fish During a long fight, handling and hook removal, a fish can become exhausted and starved for oxygen. This final stage of Catch and Release can mean the difference for the fish's survival and death.
- Grasp the fish loosely in front of the tail and cradle the belly in your other hand
- Place the fish in slow water with the head facing the current so it can regain equilibrium.
- If necessary, gently rock the fish forward and back so water passes over the gills allowing the fish to re-oxygenate and recover.
- The fish will tell you when it is ready to go by swimming away on it's own.
- Often a fish may finish its recovery by hiding behind your boots or a nearby rock.
