9 Amazon catfish
19 14, when Teddy Roosevelt led an expedition to investigate the Amazon River, a doctor accompanying him measured a giant catfish more than 9 feet long. The spindle-shaped shape of this kind of fish makes it swim fast enough in the fast-flowing river, and also makes the people who catch them with conventional fishing tackle break their rods repeatedly, which makes them helpless. Another kind of Amazon catfish, which belongs to the same family as Giant Catfish, can also grow to more than 250 pounds. It eats many fish, so it can be caught with live bait or lump meat bait.

Nowadays, because its living waters are destroyed and its species are scarce, it is called "giant panda in water".
7 bighead fish
The bighead fish can grow to 100 pounds and 9 feet long. However, the main reason that makes them the most difficult freshwater fish to catch in the world is its brute strength and its habitat. The bighead fish lives in the fastest rapids of Indian mountain rivers, where the water speed reaches 10~ 15 miles per hour.
6 Nile perch
Nile perch is the largest member of the family Crocodidae. It is said that it once had a big fish weighing more than 400 pounds, but the world record of the International Fishing Federation is 19 1.5 pounds. Nile perch is a big fish native to many waters in Africa. In the 1950s, people raised this kind of fish in Lake Keyoga, and let Nile perch prey on the fishes of the family Lepidoptera, which were not caught by local fishermen. In this way, the perch can grow bigger and have more delicious meat. Before people had time to evaluate the impact of raising perch in Lake Keyoga, Nile perch was introduced to Lake Victoria.
5 New Guinea perch

3 six-fin mullet
The longest freshwater fish in the world is undoubtedly the paddlefish, but it is followed by and even more mysterious is the six-fin carp (Wels).
