The aromatic flavour of river prawns and their creamy blob in the heads is unique. The converted prawns retain their long claws, firm flesh comparable to the original, yet the male prawns can produce eggs and are propagatable. In the past, river prawns were caught along the banks of the Chao Phraya River in Nonthaburi and Pathum Thani up to Ayutthaya. Another place you can find natural river prawns is the Trat River, Thailand's shortest river, which originates in Bantad Mountain in Cambodia. If we want to eat natural river prawns, we need to help maintain the environment, otherwise we will have no choice but to buy farmed prawns.
