Fishing in Thailand offers something found nowhere else on earth: the combination of the world's largest freshwater fish species, purpose-built fishing parks with near-guaranteed action, and the option of truly wild jungle expedition fishing — all in a country that is warm, welcoming, and easy to travel around.
Millions of tourists visit Thailand each year without realising what an extraordinary freshwater fishing destination it is. Thailand's tropical climate means there is no closed season — you can go fishing every day of the year. The fish don't hibernate; there's no ice, no mud season, and no blank days caused by cold fronts.
Mega Fishing Thailand operates guided fishing trips in and around Bangkok, Chiang Mai, and in the wild jungle reservoirs of northern and western Thailand. All tackle, transport, bait, and professional guiding is included in every trip.
Thailand's tropical climate means every month is fishing season. Here's what to expect in each season.
Best conditions for carp species. Cooler water temperatures bring big Siamese carp and Mekong catfish into the shallows. Ideal for first-timers and families.
Excellent for Arapaima and predator species. Warmer water pushes feeding activity. Early morning starts essential. Great lure and fly action for Barramundi and Snakehead.
Prime time for carp at fishing parks. Rising water levels trigger feeding. Wild reservoir fishing for Giant Snakehead is at its best. Lake fishing remains unaffected by rain.
Thailand's fishing parks are stocked and fish every single day. Guided lake fishing trips are guaranteed regardless of season. No closed season, no licence required.
Bangkok is the starting point for most Thailand fishing trips. Within 1–2 hours of the city centre you can be fishing for world-record Giant Siamese Carp and Mekong Catfish at Bungsamran Lake, casting lures for Arapaima at the predator lake, or fly fishing for Barramundi at Bang Pakong. All venues offer round-trip transport from your hotel.

For experienced anglers seeking a true adventure, Thailand's wild jungle reservoir fishing is in a class of its own. Fish vast, pristine reservoirs from longtail boats deep inside national parks. Target the legendary Giant Snakehead on topwater lures, or go multi-day with overnight stays on floating raft houses.
View jungle packages →Different species require different approaches. Here's what to expect from each style of fishing available in Thailand.
The most productive method at Thailand's fishing parks. Custom carp rods and big Shimano baitrunner reels are used with method feeders. Bait choices include bread mix, rice flour, and pellet. Expect explosive runs and battles lasting 20–90 minutes with the largest fish. Barbless hooks only at most venues — all fish are returned.
Lure and fly fishing for Giant Snakehead, Barramundi, Arapaima, and Peacock Bass is a highlight of any Thailand fishing trip. Topwater surface lures produce explosive, visual strikes. Precision casting is essential in areas with flooded trees and snags. Custom rods, braided line, and a selection of proven lures are all provided.
Thailand's coastline offers offshore sport fishing for Sailfish, King Mackerel, Barracuda, Queenfish, Cobia, and Trevally. Best season runs October to March in the Gulf. Live bait and dead bait fishing are the most productive methods; trolling and jigging also effective depending on target species.
Thailand's rivers and lakes are home to some of the world's largest and most impressive freshwater fish.
The world's largest carp species and one of the most sought-after freshwater fish on the planet. Specimens at Bungsamran Lake in Bangkok regularly exceed 80kg, with the all-tackle world record caught here. Bait fishing with method feeders and rice flour is the primary method. Fights last 30–90 minutes on heavy tackle.
The world's largest freshwater fish — a critically endangered species that can only be fished legally in Thailand's purpose-built fishing parks. Lake-stocked specimens run 30–150kg. The power of a large Mekong catfish on the rod is unlike anything else in freshwater fishing — fights regularly exceed one hour.
Thailand's most electrifying predator and a lure fishing icon. The Giant Snakehead is an aggressive ambush predator that attacks topwater lures with explosive surface strikes. Found in lakes, rivers, and jungle reservoirs across Thailand. Wild reservoir fishing for large specimens is a multi-day adventure; lake trips are available daily from Bangkok and Chiang Mai.
One of the world's great sport fish, known for spectacular aerial displays and tail-walking when hooked on lures or flies. Lure and fly fishing only at Bang Na lakes (Bangkok) and Mae Ngat reservoir. World-record class fish are present at several venues near Bangkok.
Also called the Dog-eating catfish in Thai — an enormous predatory catfish that coexists with carp and Mekong catfish in Thailand's lakes. A powerful, fast-swimming fish that regularly exceeds 40kg at Bungsamran Lake. Takes bait intended for carp and catfish, giving unexpected drama to any session.
The "Tiger of the River" — a powerful, hard-fighting carp relative that inhabits clear mountain streams and rivers in northern Thailand. Targeting Mahseer typically involves multi-day river expeditions in the Golden Triangle region. Rare and challenging; landing a large Mahseer on fly is considered one of freshwater fishing's greatest achievements.
Thailand's fishing parks have been stocked with spectacular imported species from the Amazon, USA, and Africa — creating multi-species fishing not available anywhere else in the world.
The world's largest scaled freshwater fish — up to 200kg and 3 metres in length. Thailand's predator lake holds the biggest population of Arapaima in Asia. Lure, fly, and dead bait fishing. Specimens over 100kg regularly caught.
A spectacular Amazon predator with a vivid red tail. Strong, fast-fighting fish regularly caught to 30kg+ at Thailand's specimen lakes. Takes lures, dead bait, and large pellets. Available year-round at Bangkok and Chiang Mai venues.
A prehistoric-looking ambush predator now self-sustaining at several Thai lakes. Best targeted on topwater lures and poppers. Specimens reach 40–50kg. Unforgettable visual strikes on surface lures.
The Amazon's most prized sport fish — famous for explosive strikes on surface lures. Present at Dreamlake Resort in Chiang Mai. Pound-for-pound one of the hardest fighting fish available in Thailand. Best on small lures and flies.
Fishing in Thailand's natural rivers and public lakes is very different from the fishing park experience. Rivers like the Mekong, Ping, and Chao Phraya once held enormous populations of giant catfish and carp, but wild stocks have been heavily reduced over the past 50 years by over-fishing, gillnets, longlines, and the construction of hydropower dams that have blocked migration routes.
There is no fishing licence required in Thailand for public waters, and there are no bag limits, minimum sizes, or closed seasons. The native species found in Thailand's fishing parks — Giant Siamese Carp, Giant Mekong Catfish, Chao Phraya Catfish — are all critically endangered in the wild and almost never caught on rod and line outside of purpose-built fishing parks.
This is the reason Thailand's fishing parks exist and why they matter: the fish stocked in them are bred in captivity, not taken from the wild. A day at Bungsamran Lake is not just incredible fishing — it is one of the only ways left on earth to experience these magnificent animals.
Reservoir fishing for Snakehead and jungle species is the one area where productive wild fishing in Thailand remains accessible. Thailand's vast national park reservoirs — Mae Ngat, Srinakarin, Queen Sirikit — hold healthy populations of Giant Snakehead, Jungle Perch, Tilapia, Rohu, and Mud Carp. These trips require experienced guides with local knowledge and are best suited to anglers with some lure fishing experience.
All tackle, transport, bait, and professional guiding included. Day trips and multi-day packages available from Bangkok and Chiang Mai.
Many visitors do not realise what a truly unique and amazing place Thailand is to go fishing.
There are many weird and wonderful exotic tropical fish species here and some of the world's largest freshwater mega fishes.
The Giant Siamese Carp is Thailand's most prized freshwater fish species and one of the largest carp species in the world. Growing to weights exceeding 300 pounds (140kg), these magnificent fish are native to Thailand's river systems including the Mekong, Chao Phraya, and Mae Klong rivers.
Fishing techniques: Traditional carp fishing methods work best - bottom rigs with bread-based boilies, sweet corn, or specialized Thai baits. Bungsamran Lake in Bangkok is world-famous for Giant Siamese Carp fishing with fish to 200+ pounds caught regularly. Most anglers use 30-50lb tackle due to the fish's incredible power and stamina.
The Giant Mekong Catfish is officially the world's largest freshwater fish species with specimens recorded to 646 pounds (293kg). These critically endangered catfish are now bred in captivity at specialized fisheries in Thailand, providing anglers with incredible fishing opportunities while supporting conservation efforts.
Where to catch them: Bungsamran Lake Bangkok and Borsang Lake Chiang Mai stock giant specimens. Catfish fishing uses similar tactics to carp - bottom fishing with bread baits, pellets, or specialist pastes. Fish over 300 pounds are caught each season providing lifetime memories for lucky anglers.
Arapaima fishing in Thailand is on every serious predator angler's bucket list. These South American monsters are the world's largest freshwater predatory fish, reaching lengths of 10+ feet and weights exceeding 400 pounds. Their aggressive strikes and acrobatic fights make them the ultimate lure fishing trophy.
Fishing methods: Lure fishing with large topwater plugs, jerkbaits, and swimbaits is most exciting. Fly fishing for Arapaima using large streamers provides incredible sport on heavy tackle. Bait fishing with live or dead fish is also productive. We guide Arapaima fishing trips at specialized predator lakes stocked with multiple Amazon species.
The Giant Snakehead is Thailand's most exciting native predatory fish. These aggressive hunters grow to 40+ pounds and are famous for explosive topwater strikes that test anglers' nerves and tackle. Snakehead fishing is pure adrenaline - watching your lure get smashed on the surface never gets old.
Best techniques: Topwater lure fishing is the preferred method - frog lures, poppers, and walking baits work excellent. Early morning and late afternoon provide the best topwater action. We offer multi-day jungle snakehead fishing expeditions to remote reservoirs like Srinakarin Dam where wild snakeheads hunt in pristine waters surrounded by jungle wilderness.
Barramundi fishing in Thailand offers incredible light tackle sport fishing opportunities. These silver predators grow to 30+ pounds in Thai waters and are prized for their spectacular aerial displays and hard fighting abilities on lures and flies. Barramundi are found in both freshwater and brackish coastal environments.
Where to fish: Bang Pakong River near Bangkok provides excellent Barramundi fishing on lures and fly tackle. Purpose-built fisheries also stock quality Barramundi. Use soft plastic lures, hard jerkbaits, or large streamers on fly. Early season (October-December) provides peak action before the hot season.
Thailand's fishing lakes stock an incredible variety of exotic imported species alongside native fish, creating unique multi-species fisheries found nowhere else on earth.
