Fishing Thailand for the enormous Amazonian Arapaima Gigas or Pirarucu is a highly attractive proposition for international specimen anglers wishing to do battle with one of the world’s largest freshwater fish.
The awe inspiring armour plated Arapaima Gigas or Pirarucu is a monster freshwater fish indigenous to Brazil, Peru, Colombia and several other countries in the Amazon basin in South America but has become endangered due to overfishing and habitat destruction.
Although the Arapaima or Pirarucu is a monster fish that is not indigenous to Thailand this monster fish species ranks amongst the largest freshwater giants of Thailand.
Arapaima and various other monster fish have been introduced into Thailand by enterprising fish farmers in the last two decades for supply to commercial fisheries and ornamental ponds.
The fearsome and predatory looking Pirarucu or Arapaima is the largest scaled freshwater fish in the world and is capable of reaching weights approaching 180kg’s+ and lengths of almost three metres.
The Arapaima is a prehistoric living fossil which is covered with a thick armour of large interlocking scales further adding to its ferocious and predatory appearance.
The Arapaima is one of the most striking and distinctive giant fish of Thailand displaying a vibrant bright red colouration towards the tail section of its huge elongated body.
This giant freshwater fish and apex predator has adapted through an amazing evolutionary process the incredible ability to breathe oxygen allowing the Arapaima to survive in oxygen depleted pools.
IT Lake Monsters in Thailand is an established commercial fishery situated in Ratchaburi which has a history of producing some of the largest Arapaima in the world.
IT Lake Monsters is located in Ratchaburi province which is a pleasant two hour journey through rural and agricultural surroundings from the hustle and bustle of Bangkok.

Whilst fishing for Arapaima at IT Lake Monsters in Thailand anglers will fish a variety of predator fishing methods and techniques including free lining, float fishing, dead baiting and live baiting.
Arapaima fishing in Thailand at IT Lake Monsters can be described as being highly prolific and will see the angler fishing with either live or dead bait with one rod for the entire day.
The highly predatory Arapaima or Pirarucu through thousands of years of evolution has become an extremely efficient hunter and can be seen surfacing at regular intervals around the lake as it actively hunts prey fish and gulps air. 
When hooking a large Arapaima whilst fishing at IT Lake Monsters anglers will experience the raw power of one of the largest freshwater fish in the world.
On setting the hook into the bony mouth of an Arapaima the monster fish regularily embarks on a series of unstoppable high octane runs violently stripping line from the anglers reel!
The speed and acceleration of this giant monster fish is legendary with the Arapaima aggressively thrashing its head, tail walking and sometimes becoming airborne during the course of the battle!
A battle on rod and line with the prehistoric and predatory Arapaima can last anything up to an hour testing the angler’s skill and nerve to the absoloute limit and requiring several guides to land!
After the netting of a large Arapaima it is important that the utmost care and respect is shown to the fish by allowing the giant fish a short period for recovery in a holding pen.
The Arapaima is a notoriously fragile fish after capture and is prone to mortality if not handled correctly, it is therefore essential that the Arapaima is handled by highly experienced fishing guides and given sufficient care and attention during this period of recovery.
When the Arapaima has recovered sufficiently from the stress caused during the battle the monster fish can then quickly be photographed whilst being held in the water before release.
