Seen at the market, today, are these trey ros, snakehead fish, swimming in a metal tub. The ubiquitous snakehead fish come from the fresh waters of Cambodia, while others are possibly farmed, and are available in every market all over the country.
Snakehead fish is a favourite in Cambodia. They are salted and dried (trei ngeat) or made into mouth-watering fish sour soup (samlor ma’chou). But for me they are best eaten grilled with rice and green mango salad.
