30 Species in 2 Weeks: Thailand's Ultimate Species-Hunt Itinerary
A 14-day species-chasing mission across Thailand — Bangkok pay-lakes, Khao Sok jungle, Mae Klong wild, Phuket offshore, and Phang Nga estuary for 30+ species.
No country on earth concentrates so many fishable species in such a compact and accessible geography as Thailand. The country spans two major marine systems — the Andaman Sea and the Gulf of Thailand — connected by a peninsula that holds some of the most diverse freshwater river systems in Southeast Asia. Those rivers drain out of highlands that were never glaciated, meaning the fish fauna has had millions of uninterrupted years to diversify. The pay-lake industry has layered exotic introductions on top of that: arapaima, alligator gar, redtail catfish, pacu, peacock bass — all South American or African fish that are now reliably catchable within a taxi ride of Bangkok's Sukhumvit district.
Thirty species in fourteen days is not a casual target. It requires a plan, a willingness to move fast and adapt, and the discipline to fish correctly for each species rather than throwing the same rig at every water. But Thailand is almost the only country in the world where such a tally is genuinely achievable.
Species list discipline
Keep a running log in a waterproof notebook. Photograph every species at the waterline before release. Thai fish identification guides are available in app form — iNaturalist with a Southeast Asia bias works well — but local guides will often identify species faster and more accurately by sight. Count only confirmed species, not probable ones.
The Bangkok pay-lake circuit is the easiest fishing environment in Thailand and simultaneously the most species-dense. Bungsamran Lake in the Minburi district is the historic heart of the scene — a lake that has been drawing serious freshwater anglers since the 1990s and that now reliably holds Giant Mekong Catfish in the 40–100 kg range alongside Giant Siamese Carp to similar weights. Both are genuinely among the largest freshwater fish on earth. Both bite on fermented paste or sweetcorn fished on a simple ledger rig.
IT Lake Monsters sits in a different category: a venue specifically designed around species diversity, holding arapaima, alligator gar, redtail catfish, Chao Phraya catfish, and various smaller species including rohu and striped catfish, all in a single lake. An angler who moves rigs throughout the day — surface bread for arapaima, live fish for gar, cut fish on the bottom for redtail — can realistically tick five to seven species in twelve hours without leaving the same property.
Palm Tree Lagoon adds pacu and peacock bass, two further South American introductions that require completely different techniques from the catfish lakes. Pacu on floating banana and peacock bass on soft plastics in the margins extend the tally before the trip even leaves Bangkok province.
Pay-lake species strategy
The key to maximising pay-lake species is adapting rigs rather than waiting for the fish to adapt to you. Carry at least four different rig configurations — bottom paste bait, floating bread, cut fish on a short trace, and a light surface lure setup — and rotate every ninety minutes if a specific species has not responded.
The Ratchaprapha Reservoir inside Khao Sok National Park is one of those fishing environments that no amount of prior description adequately prepares you for. The limestone karst towers rising from the water's surface, draped in primary jungle with hornbills calling from the canopy, create a backdrop that makes even modest catches feel significant. But the fish are not modest: giant snakehead to 5+ kg, barramundi to double figures, and jungle perch in tigerfish-coloured splendour are all genuinely catchable here.
Giant snakehead (Channa micropeltes) is the prestige surface species of the Khao Sok reservoir. These animals are apex predators — capable of consuming fish half their own body weight — and their response to a large topwater lure is a full-commitment explosion rather than a tentative investigation. They are also strong fighters with a tendency to dive into the nearest snag the moment they feel hook pressure: use 40 lb braid minimum and a stout leader.
The Mae Klong holds the most dramatic single encounter available in Thai fishing: a confirmed bite from a giant freshwater stingray. These animals — Urogymnus polylepis, the world's largest freshwater fish by disc width — inhabit the deep channels of the Mae Klong with a population density that makes targeted encounters realistic with a competent specialist guide. The rig is simple: large cut fish bait on a heavy running sinker, fished in the deepest available channel. The wait is often long. The bite, when it comes, is unmistakeable — a slow, heavy pull that builds into an unstoppable sustained pressure unlike any other freshwater fight.
Giant featherback (Chitala lopis) and snakeskin gourami round out the wild river target species. The featherback is a nocturnal hunter that responds to large cut baits at depth; the snakeskin gourami is a creature of shallow, weedy water that takes slow-sinking bread or dough baits on light float tackle.
The Andaman offshore phase is the logistically simplest component — hire a quality charter, leave at dawn, and let the skipper position the boat. The species list largely handles itself on a productive day: sailfish, wahoo, yellowfin tuna, mahi-mahi, dog-tooth tuna, GT, coral grouper, and barracuda all inhabit these waters. The challenge is targeted variety rather than volume — requesting a jigging pass after the trolling run adds dog-tooth and deep grouper to a day that might otherwise only deliver trolling-accessible pelagics.
The inshore Andaman — the reef zones between Chalong and Koh Racha — provides mangrove jack and barracuda in abundance on lighter tackle, filling out the saltwater tally without requiring a second full offshore day.
Phang Nga Bay is the saltwater component of this itinerary that most species-hunters overlook in favour of the offshore Andaman. That oversight is a meaningful mistake. The mangrove estuary system stretching from the Phang Nga River mouth south and east through the bay holds a brackish fauna that has no equivalent elsewhere in the itinerary: archerfish, multiple snapper species, mullet, threadfin, queenfish, small GT, horseshoe flathead, and spotted catfish — a genuinely diverse assemblage that requires completely different techniques from anything fished in the previous eleven days.
Archerfish deserve specific mention. These animals — capable of spitting water jets to knock insects from overhanging vegetation — are iconic in their biology and largely ignored by sport anglers. They respond to small floating flies and micro lures cast along the mangrove edge at high tide, and catching a confirmed archerfish is a species-quest victory of real satisfaction.
The species count at departure
A committed angler following this itinerary in optimal season (November–March) with quality guides across all legs should tally 28–32 species. Weather-related offshore cancellations are the main risk to the upper end of that range. Build contingency time into the Phuket phase rather than the freshwater legs — the pay-lakes and rivers operate regardless of weather.
Morning. Arrive Suvarnabhumi, check in near Sukhumvit. Afternoon taxi to Bungsamran Lake in the Minburi district. Day session: target Giant Mekong Catfish and Giant Siamese Carp on fermented paste and sweetcorn bottom rigs. Both species frequently exceed 40 kg here and are the two most iconic entries on any Thai freshwater species list.
Afternoon. Continue session into the afternoon peak bite. Bungsamran's guides will move you between swims if a target species is not responding — use their local knowledge. By 5 pm you should have at least two new species on the tally. Return to Sukhumvit for dinner.
Evening. Rest and repack. Tomorrow requires an early start for a second lake.
Stay. Hotel in Sukhumvit / Asoke. THB 1,200–3,000 per night.
Day 2
Bangkok — IT Lake Monsters: Arapaima, Alligator Gar, Redtail Catfish
Morning. Full day at IT Lake Monsters — one of Thailand's most species-diverse pay-lakes. Morning focus on arapaima using floating bread or surface lures. This non-native South American giant is now Thailand's most sought-after freshwater trophy. IT Lake holds specimens exceeding 80 kg.
Afternoon. Shift rigs to target alligator gar with live or cut fish baits near the surface, and redtail catfish on bottom with dead fish. Both are South American introductions that have thrived in Thai pay-lake conditions. The lake also holds Chao Phraya catfish — a native Thai giant that competes for the same baits.
Evening. Tally review at dinner: Arapaima, alligator gar, redtail catfish, possibly Chao Phraya catfish — four more species if things go well. IT Lake is genuinely productive for motivated anglers who move between methods.
Stay. Same Sukhumvit hotel.
Day 3
Bangkok — Pilot 111 + Palm Tree Lagoon: Giant Gourami, Pacu, Peacock Bass
Morning. Morning at Pilot 111 for Giant Siamese Carp and Mekong catfish consolidation, then transfer to Palm Tree Lagoon in the afternoon — a lake north of Bangkok that holds an impressive range of introduced species including pacu, peacock bass, and giant gourami.
Afternoon. Pacu respond to floating banana or corn paste fished near the surface on a controller float. Peacock bass — a South American cichlid — smash small swimbaits and soft plastics around the lake margins. Giant gourami are fished on vegetable baits. Three genuinely different fishing approaches in one afternoon.
Evening. Running total by end of Day 3: 8+ species. Rest and travel prep for the Khao Sok leg.
Stay. Final night in Sukhumvit. Early checkout tomorrow.
Day 4
Transfer to Khao Sok — Arrival at Ratchaprapha Reservoir
Morning. Early morning van or private car south from Bangkok toward Surat Thani Province. The drive to Khao Sok takes approximately 7.5–8.5 hours with stops, or 5.5 hours from Hua Hin. Alternatively, fly Bangkok–Surat Thani (55 minutes) and transfer by road to the reservoir.
Afternoon. Arrive at Ratchaprapha Dam and check into a floating raft house on the lake. Afternoon settling-in session from the raft house jetty: snakehead and snakeskin gourami on surface lures in the cove margins. Both species are excellent targets from the platform without even needing a boat.
Evening. Dinner on the raft house deck. Night fishing from the jetty for catfish — bang up bottom rigs with cut fish bait and wait. The lake holds several catfish species including walking catfish and striped catfish.
Stay. Floating raft house, Cheow Lan Lake. Basic but atmospheric.
Day 5
Khao Sok — Giant Snakehead and Jungle Perch by Kayak
Morning. Full day kayak session in the reservoir feeder arms with a local guide. Primary target: giant snakehead on surface lures. Secondary: jungle perch (Datnioides microlepis) — a striking, tigerfish-patterned species that holds along steep limestone walls in 1–3 metres of water and takes small jigs and lipped crankbaits aggressively.
Afternoon. Extend into a deeper arm for barramundi on suspending lures near submerged timber. Barramundi — or pla kapong in Thai — is Thailand's premier sport fish and a key species-quest target. Khao Sok specimens are wild animals rather than stocked fish, adding a further element of difficulty.
Evening. Evening session back at the raft house on surface lures for more snakehead. Night sounds of the Khao Sok jungle at the waterline are a category of their own.
Stay. Raft house, second night.
Day 6
Khao Sok Departure — Drive to Mae Klong River Basin
Morning. Early checkout and road transfer northwest toward Samut Songkhram Province and the Mae Klong river system — approximately 3.5–4 hours by road via Chumphon. This is a long drive; consider breaking it with a food stop at Prachuap Khiri Khan.
Afternoon. Arrive Mae Klong. Check in to a riverside guesthouse in Samut Songkhram town. Afternoon recce on the river with a local guide — the Mae Klong drains into the Gulf of Thailand and holds a remarkable mix of freshwater and brackish species including giant freshwater stingray, river catfish, and featherback.
Evening. Dinner of fresh Mae Klong prawns at a riverside market stall. Brief gear check for the next two fishing days.
Mae Klong River — Giant Freshwater Stingray and Featherback
Morning. Full day on the Mae Klong with specialist guide. The giant freshwater stingray (*Urogymnus polylepis*) is found here in numbers unmatched anywhere else in Thailand. Target with large cut fish baits on heavy bottom rigs in the river's deepest channels. A positive identification — even without landing — counts as a species.
Afternoon. Switch rigs for giant featherback (Chitala lopis) — a blade-shaped, hump-backed predator that takes cut fish and large soft plastics at depth. The featherback is one of Thailand's most distinctive native species and a meaningful addition to any serious species tally.
Evening. Catfish consolidation session at dusk — the Mae Klong holds striped catfish, walking catfish, and spotted catfish, all of which feed more actively as light fails. A productive evening can add two or three catfish species to the tally.
Stay. Samut Songkhram guesthouse.
Day 8
Mae Klong — Snakeskin Gourami and Departure for Phuket
Morning. Final Mae Klong morning session targeting snakeskin gourami in the reed margins and flooded rice-paddy drainage channels near the river — a different habitat from the main channel and a species that rewards patience with a controller float and small dough bait. The snakeskin gourami is a beautiful, underrated target that few visiting anglers specifically seek.
Afternoon. Road transfer south to Chumphon for the flight to Phuket, or direct road south to Ranong and ferry across to Phuket via the Andaman coast route. Check in to accommodation near Chalong pier.
Evening. Dinner near the Chalong roundabout. Brief with the saltwater charter captain for tomorrow's offshore day if possible.
Morning. Dawn departure from Chalong or Boat Lagoon on a full-day offshore charter. The Phuket FAD grounds in the Andaman are the centrepiece of the saltwater phase. Troll a spread of ballyhoo, lures, and squid daisy-chains across the FAD zones targeting Indo-Pacific sailfish — the signature Andaman species. Sailfish up to 45 kg are realistic in peak season; a productive FAD day can deliver multiple hook-ups.
Afternoon. Post-FAD reef session on the return leg targeting GT on the popper and wahoo on the troll. A high-speed wahoo strike at 20 knots on a trolled lure is one of saltwater fishing's most violent sensations. Yellowfin tuna may show around the FAD at any point during the day.
Evening. Back at dock by 5 pm. Salt in the reel handles, burn in the forearms, and four new saltwater species on the list. Dinner at Rawai seafood pier.
Stay. Same Chalong accommodation.
Day 10
Phuket — Jigging and Popping: Dog-Tooth Tuna, Coral Grouper, Mahi-Mahi
Morning. Second offshore day with a jigging/popping focus rather than trolling. Dog-tooth tuna (*Gymnosarda unicolor*) are the signature deep-jig species of the Andaman — powerful, broad-shouldered animals that hit slow-pitch jigs at 60–100 metres and run in unstoppable first surges. A 20 kg dog-tooth on a PE3 slow-pitch outfit is a serious physical event.
Afternoon. Reef section targeting coral grouper on jigs and mahi-mahi on light tackle along FAD flotsam lines. Mahi-mahi school under any floating debris in open water and hit surface lures and small jigs readily — they are one of the most visually spectacular catches in the Andaman, with electric-green and gold flanks that fade within minutes of landing.
Evening. Rest day prep. Transfer tomorrow to Phang Nga Bay for the brackish and estuary phase.
Stay. Same accommodation.
Day 11
Phuket — Koh Racha Reef: Mangrove Jack and Barracuda
Morning. Inshore session in the Chalong Bay approaches and Koh Racha Noi shallows. Mangrove jack (*Lutjanus argentimaculatus*) is a target species frequently encountered on the Andaman inshore reefs — a solid, red-flanked predator that fights deep and strong. Target on 40–80g jigs in reef gullies.
Afternoon. Barracuda (great and pickhandle species) are abundant around the inner reef structures throughout this region. They take surface pencil lures and jigs with kamikaze aggression and run long, fast, first-run bursts. Two more species added before the Phang Nga transfer.
Evening. Pack and transfer to Phang Nga Bay area accommodation. The Phang Nga estuary leg begins tomorrow.
Stay. Guesthouse in Phang Nga town or Koh Yao Noi island.
Day 12
Phang Nga Bay — Mangrove Estuary: Snapper, Mullet, Archerfish
Morning. Longtail boat session in the mangrove channels of Phang Nga Bay — a vast estuary system of drowned limestone karst, mangrove passages, and brackish creek networks that holds a completely different suite of species from either the Andaman offshore or the freshwater lakes. Early morning is productive for mangrove snapper (small, numerous, aggressive on small jigs and shrimp baits).
Afternoon. Archerfish (*Toxotes jaculatrix*) inhabit the shallow mangrove creek margins and can be targeted with floating lures cast tight to overhanging vegetation. This extraordinary species is a genuine species-list tick that few sport anglers specifically target. Mullet — multiple species — are present in the brackish zones and are challenging to catch on rod and line but rewarding when landed.
Evening. Night session in a mangrove channel for estuary catfish and moon estuary fish. The mangrove system at night is dramatically alive.
Stay. Same Phang Nga accommodation.
Day 13
Phang Nga Bay — Mudskipper Channels and Horseshoe Flathead
Morning. Specialist morning session targeting species in the extreme shallow mangrove margins: small flathead species (horseshoe flathead are present in the mudflat zones), spotted catfish in the creek mouths, and — for the committed — mudskipper, which can be caught on tiny hooks baited with worm in the mud channels and genuinely counts as a species on some hardcore lists.
Afternoon. Afternoon longcast session from the mangrove edge into the bay for queenfish and small GT — two final species for the saltwater tally. Queenfish (*Scomberoides commersonnianus*) travel in packs along the mangrove edge and smash surface lures in a very convincing GT impersonation.
Evening. Count the tally. Aim: 28+ species by end of Day 13. Dinner and celebration — one final session remains.
Stay. Same Phang Nga accommodation.
Day 14
Final Session — Phang Nga Estuary + Phuket Airport Departure
Morning. Dawn bonus session in the Phang Nga estuary or back at Koh Yao Noi for any missing species. Threadfin, small barramundi, and olive flathead are all realistic additions. A longcast at dawn from the mangrove shoreline has a way of producing surprises on the final morning of a trip.
Afternoon. Transfer to Phuket International Airport for departure. The species tally — realistically 28–32 depending on conditions, season, and angler skill — represents a genuinely comprehensive cross-section of Thai fishing ecosystems. No single venue and no single fishing style has dominated; this trip has demanded all of them.
Evening. Flight home. Start planning the return trip to fill the gaps.
Stay. N/A — departure day.
FAQ
Frequently asked questions
Is 30 species in 14 days a realistic target?+
Yes, for a motivated angler fishing with good guides, the right rigs, and no lost days to weather. The itinerary deliberately covers five distinct ecosystems — pay-lake, jungle reservoir, wild river, offshore Andaman, and mangrove estuary — each of which holds a different suite of species. Bangkok pay-lakes alone are stocked with 8–12 exotic and native species in a single venue. The main risk is weather impacting the offshore Phuket sessions.
What is the best time of year for this itinerary?+
November through April is optimal. The Andaman offshore sessions are only viable in calm Andaman conditions (the northeast monsoon period). The freshwater and estuary components work year-round, but the Mae Klong is best in the dry season when water clarity improves stingray visibility.
Do I need to hire guides for every leg?+
For the offshore Phuket sessions, yes — a licensed charter is both required and essential. For the Mae Klong stingray, a specialist guide is strongly recommended. For Bangkok pay-lakes and Khao Sok raft-house fishing, guides are optional but significantly increase species count efficiency. Budget for guides across all legs.
Which leg is most likely to produce new species I have never caught before?+
The Phang Nga estuary section consistently surprises even experienced anglers — archerfish, horseshoe flathead, multiple small snapper species, and the various mullet and threadfin that inhabit the mangrove margins are rarely specifically targeted on other Thai fishing itineraries. The Mae Klong stingray leg is the most dramatic single-species encounter available in Thailand.
