Catlocarpio siamensis
The giant barb — the largest carp in the world and a legendary target in Thailand's fishing parks and rivers. Siamese carp grow to enormous sizes, feed on plant matter and pellets, and give long, powerful, unforgettable fights. Most are caught at managed lakes on specialised carp gear.
Siamese carp are usually targeted at managed lakes and rivers with pellet and dough baits fished on the bottom over a baited swim. Build up feed to draw fish in, present a bait on strong carp tackle, and be ready for long, dogged runs from an enormous fish. This is patient, gear-intensive fishing with a giant payoff.

Giants of large rivers and, most accessibly, managed lakes across Thailand and neighbouring countries, feeding on plants and pellets over the bottom.
Siamese carp have a very large head and deep body with big scales; other carps are smaller and slimmer.
The giant barb's sheer size and deep, heavy body separate adults from all lookalikes.
Size limits, bag limits, seasons, and gear rules change every year and differ by country and province (and often by individual water). Always verify with the official source before keeping fish.
