Catfish are popular among North American anglers, but they can also be found all around the world, with two of the largest species—the Wels and the Giant Mekong—inhabiting waters in Europe and Southeast Asia. South America, and especially Brazil, is home to several unique species as well. There are more than 30 international catfish species in the world record book, as maintained by the International Gamefish Association. Here’s a look at 15 of the all-tackle world records from around the planet.

Mekong Giant Catfish – 260 pounds

Martin David Kent is the IGFA’s all-tackle world record holder for Mekong giant catfish with a 260-pounder caught Nov. 29, 2010. Kent was fishing out of Gillams Fishing Resorts in Krabi, Thailand, and the catfish was 79 inches long with a 46-inch girth. He was geared up for big fish, wielding a Free Spirit Cat Tamer with a Penn 760 Live Liner reel spooled with 80-pound Berkley Whiplash line. He was bait fishing using a paste ball.

Mekong giant catfish are part of the family of “shark catfishes,” which are migratory. They are typically found in medium-to-large-sized rivers. Although they are herbivores, they are willing to take other food in captivity. The Mekong giant catfish is one of the fastest growing fishes in the world, said to be capable of reaching up to 400 pounds within six years. Unlike other large catfish in the Mekong system, these giants have no teeth and minimal, if any, barbels. International trade of the fish is banned, and it is considered an overexploited resource 

Kent’s fish, while massive, is not the biggest Mekong cat ever caught. According to National Geographic, a nine-foot, 646-pound Mekong giant catfish was caught in Thailand in 20015. That fish is listed in the Guinness Book of World Records as the largest freshwater fish ever recorded.

Redtail Catfish – 123 pounds, 7 ounces

According to the IGFA, these fish can even move overland under damp conditions by “crawling” with its pectoral spines. Anything swimming, crawling, slithering, or flying that it can fit in its mouth is suitable for a meal. It is also an important food source in many cultures around the world.
