One of the best things you can practice on the water is safety, but in this case, it's safety for the fish. If you plan to practice catch and release here are the things you need to know to make sure you don't harm the fish.
Nets are an essential piece of equipment for all anglers from mountain streams to deep water dropoffs. Some fish are more delicate than others, but it’s important to treat all of them as gently as possible. Gaffs should never be used to land a fish that you intend to release because they cause immediate damage to fish which greatly reduces their chances of survival.
When it comes to nets make sure to use one that is appropriately sized for the fish you intend to catch. A net that is too small risks fish being dropped or getting stuck which causes more stress and lengthens the release process. Larger nets might be more cumbersome to handle but are generally easier on the fish. The net material is also important when handling fish because of the thin protective slime layer that coats their skin. Nylon nets are rough and scratchy when fish are pushed into them and pulled out which can damage their skin. Rubber nets are preferred when landing fish because they are smooth and not tough on their skin, scales, or slime.
Once a fish has made it to the boat, it’s important to have your tools for unhooking the fish nearby. Having the tools on hand will help shorten the length of time you need to handle the fish which is always better. The best tools for hook removal include needle nose pliers, clamps(such as hemostats), or any of the commonly available hook removers.
Needle nose pliers might be the most versatile hook removers and can be found in the tackle box of almost every angler. When needle nose pliers are too big or tough on hooks, hemostats can be especially handy for working on thin wire hooks or smaller fish. In certain cases, specialty hook removal tools can be useful but make sure you have used them before trying to unhook a fish.
If you plan to release the fish, wet your hands to reduce how much of their slime coat is disturbed. Keeping a fish in the water while taking pictures or unhooking them is ideal. Most fish cannot breathe air so It’s best to only keep fish out of the water for short periods of time that are no longer a minute or two.
Strong fish are hard to handle but flipping them upside down and using a wet rag to cover their eyes can calm them down. It’s always better to hold larger fish horizontally with two hands, one hand under the belly and the other under the head. It’s important to support the body of the fish out of water because their body cannot support their weight out of the water. Handle fish with care and respect from the time you land them until they are back in the water.
Using nets can also be a useful way of containing a fish while you work on unhooking it while keeping it in the water. If you need to remove the fish from the water pull it out of the water with the net and pick it up with wet hands or gloves. Use the needle nose pliers or other hook removal tool to grab the hook and push it out in the opposite direction that it went in. Do not try to tear a hook out of a fish's mouth, that will only cause unnecessary damage to the fish and hurt its ability to survive. If the hook does not come out try using slightly different angles or twisting the hook slightly to help free up the barb. Once the hook is removed place the fish back in the water and begin reviving the fish.
After you have fought with a fish, tired it out enough to land, unhooked it, and finally placed it back in the water, the fish will be weak and suffering from low oxygen. With the fish in the water, hold its tail and support its body while pointing its head into the flow of water. Allow the water to flow through the gills of the fish while gently moving it back and forth to start allowing the fish to breathe and get oxygen. The fish will begin moving and will eventually swim off on its own. If a fish is released and does not swim off grab the fish and continue trying to resuscitate it.
If fish did not survive being caught by anglers fishing regulations would look a lot different. Catch and release is a big part of the sport because every angler releases fish that will hopefully be caught by another lucky angler someday. By using these best practices while handling fish and unhooking them we are doing not only what’s best for the fish's health but also the sport and conservation. We all want to see the fish populations and waters we love improve, and one of the best ways to do that is by properly handling and releasing fish.
