The Pa Va is also known as the Labeo Dyocheilus, or the Lotus Fish, the Pla Bua, Boalla and Heel-Gorya.
In Laos, it reaches a maximum length of 45cm although accounts in Luang Prabang suggest this carp can grow even bigger. It's common in the Himilayas and is well-known in India, where it can grow up to a meter. The Pa Va spawns around July to August.
They provide good thick fillets, and good for a soup dish known as Keng Som Houa Pa Va Sai Het Sed, and a dish known as Sa Ton Pa Va, a fish salad that works best with a female fish and its roe.
