Responsible Catch and Release in Pond Fishing
You wanted to help in conserving the fishery. You caught a small barramundi and decided to release it back. You haphazardly get the hook off of its mouth and quickly toss it back to the pond with the hope that it will grow bigger to fight another day. But did you do it right?
Did you even bother to check if the fish had a fighting chance?
Catch and Release in pond fishing is a fairly new concept for local anglers. The current mindset is “as long as I return it, it will live”. This article provides guidelines to dispell this misconception and ensure that the released fish survives.
On fighting the fish and landing it
When fighting a fish which you intend to release, it is best to minimize the stress that you are causing it. Having a hook in its lip is torture enough. Don’t unnecessarily tire out the fish just to enjoy the fight. Try to land the fish as safely and as stress free as you can. Use appropriate tackle and bring the fish in quickly to reduce exhaustion. Using tackle that is too light and playing the fish to exhaustion depletes the fish’s energy reserves and can cause mortality.
When landing the fish, avoid slamming it unto the boat or the pond’s bank. Use a specially designed Catch and Release net with a small cloth mesh to prevent the fish scales from being damaged.
Handling the fish
Minimize harming the fish further when handling it. Wet your hands or gloves or use a wet non abrasive towel before touching the fish to prevent scraping off its protective mucous or slime. Carefully hold the fish to avoid dropping it. If you can, you may hold it by the lip with additional support to the body. Do not hold large fish vertically by the lower jaw. In a study, 50 of 50 barramundi died after being held this way.
Avoid touching the gills as much as possible. Know the best way to handle the fish species you are targeting and have release equipment ready. Using release tools is safer for the fish and for you.
Unhooking
Once the fish has been secured, you can then remove the hooks. There are many devices for removing hooks from fish. Commercial dehookers, forceps and long nosed pliers can be found in most tackle shops.
Debarbing your hooks will greatly make this experience easier for you and the fish. Pinch the hook barb using a long nosed plier or you can just file it off. If the fish has been gut hooked, don’t force yourself to be an instant surgeon and operate on the fish. It will stand a better chance if you just cut off the line as short as possible and leave the hook on. The fish’s digestive system will eventually break it down (with the exception of stainless and other special coated hooks). This is a lot better than trying to dehook the fish and ripping its guts out. Don’t think twice about losing your gamakatsu or mustad hook over causing the fish to die with your attempts to retrieve the hook.
To minimize gut hooking in the first place, it helps to learn to strike the fish right. Furthermore, using circle hooks makes a lot of difference. Avoid using kahle hooks, they are sometimes sold as circles because they also set themselves, but only true circle hooks are suitable if you want the fish to survive. Furthermore, most studies on circle hooks show that hooks with no offset are more effective in hooking the jaw than those with an offset.
For lures, you may also debarb the treble hooks or replace them with single hooks to make unhooking easier.
Venting
Venting only becomes necessary for fish caught in deep waters (25 meters or more). The procedure involves piercing the swim bladder to deflate it. You don’t have to vent fish in any of the ponds in Valenzuela as the water is usually below 2 meters.
Releasing
Leaving the fish in the water during release is best, especially for bigger ones that may be hard to handle by yourself. If the fish is in good shape, merely hold it headfirst into the current or open water. If it is severely lethargic, hold the bottom jaw agape and gently move the fish forward or do a figure 8 movement. This will revive the fish by promoting water to flow over the gills. Continue until the fish is able to swim unassisted. Severely exhausted fish may require several minutes to revive. Some fish will swim a short distance, become disoriented, sink to the bottom and die, so be observant.
You may also use a specially designed Catch Release net with a small cloth mesh to prevent the fish scales from being damaged.
