Are you interested in catching the Mekong Giant Catfish, one of the largest freshwater fish in the world?
While fishing in Bangkok, I was fortunate to catch a number of these beautiful yet endangered creatures. Now I’d like to bring awareness to just how bad of shape they are in.
I believe if we can showcase how impressive these fish are to catch and release, we can spark a movement to protect them before they go extinct.

Giant Mekong Catfish are big river fish native to the Mekong basin. Located in Southeast Asia, this giant catfish is unique. It has grey to white coloring, no stripes, no teeth, and has little to no barbells. Juveniles have barbells that shrink as they grow older.
This huge catfish is a critically endangered species because of overfishing and over-harvesting. It used to be found from the lower Mekong all the way to the northern part of the river in the Yunnan Province of China.
Now it mainly exists in the middle Mekong region.

Mekong Catfish Habitat
The Mekong catfish can only be found mainstream in the Lower Mekong and select locations such as Myanmar, Thailand, Lao PDR, Vietnam, and Cambodia. This large freshwater fish used to be common further north but now sightings of what some consider the biggest catfish are non-existent in those regions.
Some experts are of the opinion that the numbers have reduced by about 90% in the last 10 years. This is a massive decrease. In fact, there may be only 100 left in the wild…
How to Catch Giant Mekong Catfish
Catching this huge freshwater catfish is no small feat and you need some sophisticated fishing gear to fight this monster. One of the largest freshwater fish in the world requires serious equipment.
Since these fish can get over 100 pounds, use braided fishing line that’s up to the task. You’ll also want a medium-heavy to a heavy class rod. It takes a lot of brute force to land this catfish after all.
One of the best rod and reel you can use to snag this fish is the PENN Fierce 6000 reel that is fixed to a 6’ long rod. Besides being tough, this rod also gives adequate bending action which will come in handy when you hook this powerful catfish.
Mekong Catfish Rig
Catching these cats is pretty straightforward. Use a coiled baitholder and add a large dough ball to lure them in. Make the dough with coconut milk to make it more attractive to the fish.
Mekong catfish use its powerful gills to suck in bait like a vacuum cleaner. Since the fish has no teeth, use chicken feed dough to entice it to take a gulp. While in Bangkok, it wasn’t uncommon for us to catch the fish with just a hook and throwing some bread in the water. They would just suck it all up!
You can also use sticky rice and flavor it with fish and algae. Since the bait will dissolve in the water it should act as chum that this giant catfish cannot resist. Make sure that about 14 inches of the leader run from the baitholder with a J-hook at the end. Attach a piece of bread to the hook under the surface of the bait ball.
Mekong Catfish Fishing Tactics
- Apply constant tension to the line when you hook the fish. Any slack in the line will allow the catfish to spit out the hook in its mouth.
- This big river fish will make a dash around the pond when it is hooked and will drag the line. Make it tire itself out by maintaining pressure on the line till you can reel it in easily.
- These catfish are easier to catch during the dry season in small lakes. The location you choose to fish in will dictate whether you should use doughballs, fresh dead bait, or shrimp. Ask the locals for help before experimenting.
Mekong Catfish Fishing Tips
- Make sure the dough ball you use as bait is at least the size of a baseball. This huge fish can gulp it down easily.
- Prevent the catfish from making a dash to the pier or submerged foliage or it may escape.
- These large fish like to hide in roots that are tangled under the water during midday for shade. A good idea is to start fishing after 5 pm when the sun is not on the water and the cats swim out in the open.
Mekong Catfish Seasons
